National Highways
View on Wikipediafrom Wikipedia
National Highways (NH), formerly Highways England and before that the Highways Agency, is a government-owned company charged with operating, maintaining and improving motorways and major A roads in England.
Key Information
It sets highways standards used by all four UK administrations, through the Design Manual for Roads and Bridges. Within England, it operates information services through the provision of on-road signage and its Traffic England website, provides traffic officers to deal with incidents on its network, and manages the delivery of improvement schemes to the network.
Founded as an executive agency, it was converted into a government-owned company, Highways England, in April 2015. As part of this transition, the UK government set out its vision for the future of the English strategic road network in its Road Investment Strategy. A second Road Investment Strategy was published in March 2020, with the company set to invest £27 billion between 2020 and 2025 to improve the network as described in the strategy. The current name was adopted in August 2021.
History
[edit]
In March 1994, the Highways Agency was created as an executive agency of the Department for Transport.[3]
As part of the Department for Transport's 2010 Spending Review settlement, Alan Cook was appointed to lead an independent review of the government's approach to the strategic road network.[4] It recognised that the Highways Agency was closer to central government than other infrastructure operators, resulting in a lack of a strategic vision and certainty of funding due to the wider policy environment in which it operated, as well as the limited pressure to drive efficiencies compared to that faced by regulated sectors.[5] In April 2015, it became a government-owned company with the name Highways England.[6] In July 2015, Jim O'Sullivan became chief executive, replacing Graham Dalton.[7]
In 2020, the agency launched an advertising campaign using the song "Go West" by Village People and covered by Pet Shop Boys. The lyrics changed to "Go Left", encouraging people to stop on the left hand side of the motorway in case of breakdown.[8]
In August 2021, Highways England was rebranded to National Highways, removing any reference to England from its name. This move coincided with the permanent appointment of Nick Harris as CEO, after taking over as interim CEO from Jim O’Sullivan in February 2021.[9] It was suggested that the 'national' in the new name refers to the fact that the company is responsible for setting highways standards for the whole of the UK,[10][11] through the Design Manual for Roads and Bridges, even though decisions on the building and maintenance of roads outside of England are devolved to the Scottish Government, Welsh Government and Northern Ireland Executive.[12]
The renaming met with some criticism, being the third name for the agency in six years, and with reports that 'Highways Agency' is colloquially used more than either newer name.[11] The name has also attracted criticism from the other countries of the UK, particularly in Wales where the use of 'national' has been criticised despite transport being devolved to Wales.[13]
Responsibilities
[edit]
National Highways is responsible for operating, maintaining and improving the strategic road network (SRN) – the motorways and major A roads in England. The SRN comprises over 4,000 miles (6,400 km) of road and includes structures such as bridges, tunnels, drainage systems and technology assets including variable message signs and cabling. The SRN includes only around 2% of the total road length in England, but it carries around a third of all its motor vehicle traffic.[14]
National Highways is responsible for the Design Manual for Roads and Bridges (DMRB) providing the standards, advice notes and other documents relating to the design, assessment and operation of trunk roads, including motorways in the United Kingdom.[15] The manual is produced by National Highways in conjunction with the devolved governments of Wales,[16] Scotland[17] and Northern Ireland.[18] The manual is also used in some parts of the Commonwealth.[19]
The authority produces the Manual of Contract Documents for Highway Works (MCHW), and Asset Maintenance and Operation Requirements (AMOR) which supersedes the Network Maintenance Manual and Routine and Winter Service Codes, and its predecessor the Trunk Road Maintenance Manual. Contractors and subcontractors are generally paid via a project bank account, which is the agency's default mechanism for ensuring that payments flow down through the supply chain, and prevent payment hold-ups for sub-contractors undertaking work on behalf of a prime contractor.[20]
Operating the network
[edit]National Highways' operations are split into areas[21] which are loosely based on the regions of England. These regions are subdivided into nine operational areas. Eleven areas and routes are managed by DBFO (Design-Build-Finance-Operate) companies.[21] Each area is managed and maintained by an area team, with a Managing Agent, MA, and a contractor, the Managing Agent Contractor, MAC. The M6 Toll is a PFI concession, which is part of the strategic road network.

Improving the network
[edit]In common with the regulated sectors, National Highways works to fixed funding periods called Road Periods. Each Road Period is currently five years in length, and a particular Road Investment Strategy (RIS) will broadly align with this. Before a new Road Period starts, National Highways will provide the Secretary of State for Transport with an SRN Initial Report, including an assessment of the state of the SRN, maintenance and enhancement priorities, and future development needs. Following this, the government produces a draft RIS setting out the high-level outputs that National Highways will need to deliver within the corresponding Road Period, alongside the proposed funding.[28]
National Highways will then respond with a Strategic Business Plan detailing its plans for delivering the RIS. This is reviewed by the Highways Monitor to assess whether the proposed requirements are deliverable with the proposed financial resources and sufficiently challenging. After the Strategic Business Plan and RIS are finalised, National Highways must deliver the agreed outputs and will be monitored on its progress by the Highways Monitor.[29]
Development of the SRN is achieved through National Highways' capital investment programme, funded entirely by government through grant-in-aid and set out in the first Road Investment Strategy. For Road Period 1 (2015–20), Highways England invested around £15 billion in its network, with additional funding to address other local challenges in proximity[clarification needed] of the SRN relating to the environment; air quality; cycling, safety and integration; and growth and housing.[30]
For Road Period 2 (2020–25), National Highways will invest over £27 billion in its network, of which £14 billion is for road enhancements.[31] The rest is for operating, maintaining and renewing its roads, and further funding to address challenges on the environment and wellbeing; users and communities; innovation and modernisation; and safety and congestion.[32] As of this Road Period, National Highways' activities will, at least in part, be funded by vehicle excise duty.[33]
Organisation
[edit]
Head office
[edit]The company head office is in Bridge House, on a one-way gyratory in Guildford, Surrey. Previously its head office was in Dorking, Surrey. In 2014, the agency signed a ten-year lease with the owner of the Guildford facility.[34]
National Traffic Information Service (NTIS)
[edit]Sopra Steria operates the National Traffic Information Service (NTIS) on behalf of National Highways. NTIS is the information hub of England's strategic road network.[35]
The service is based at Quinton, Birmingham and is responsible for providing accurate, historical, real-time and predictive traffic and incident information to businesses, the travelling public and National Highways' operations.[35] It collects real-time traffic information from over 10,000 fixed sites on the motorway and all-purpose trunk road network from MIDAS and Traffic Monitoring Unit (TMU) electronic loops in the road surface and automatic number plate recognition (ANPR) cameras at the roadside.
It uses anonymous floating vehicle traffic data (FVD) from vehicles to supplement the fixed traffic monitoring sites.[citation needed] NTIS has access to nearly 2,000 CCTV cameras,[36] 300 weather stations, 4,600 roadside electronic signs, 16,000 roadside electronic matrix signals and incident data from over 250 operational partners, including the police and local authorities.[37]
It processes this data to create useful intelligence for operational decision making and dissemination of current and predictive information to the public using the 4,600 roadside variable-message signs,[38] the Highways England website[39] (including a mobile version), social media channels such as Twitter and the telephone-based Highways England customer contact centre[40] and distributing information to the media and businesses through a number of data feeds.[36][41] These feeds are widely used by organisations such as the BBC and local newspaper websites for their own traffic information. Services such as Google Maps and sat-nav operators also use National Highways' data for their traffic information.
Area teams
[edit]The motorway network is divided into "Areas". They are contracts that are awarded by the Department for Transport. The area teams work alongside the National Highways Traffic Officer Service – providing incident support, emergency traffic management and infrastructure maintenance. They are responsible for the management and operation of the roads in their area.[42] In 2009, fleet tracking has been deployed to assist area teams to manage their specialist winter maintenance vehicles during the cold snap.[43]
Staff
[edit]National Highways employs uniformed traffic officers; on-road and control room, as well as specialist staff for work in engineering, surveying, accountancy, and administration. There is a graduate entry scheme, with general entry and specialist engineering entry options.[44] For the Traffic Officer Service, each team is supervised by a team manager, one of between six and eight such managers generally working together, to ensure 24-hour management cover.
Fundraising
[edit]National Highways is partnering with The Tree Council to donate thousands of trees for community projects across the UK, aiming to plant three million trees by 2030 and support biodiversity. The article highlights corporate partnerships and fundraising initiatives, including BNP Paribas's donation for an IT suite upgrade, Peninsula Group's Giving Tuesday fundraiser, and M&S's commitment to training young people through its Marks & Start program.[45]
Governance and accountability
[edit]Formal governance structure
[edit]National Highways is a private company limited by shares, wholly owned by the Secretary of State for Transport.[46] The National Highways Board is the primary governance arm of the company and is accountable to the Secretary of State for Transport. The Board delegate responsibility of the day-to-day running of the company to the Chief Executive who, as the Accounting Officer, is accountable to the Permanent Secretary of the Department for Transport, as the Principal Accounting Officer, for the stewardship of public funds. The Principal Accounting Officer and Secretary of State for Transport are both ultimately accountable to Parliament for the activities and performance of National Highways.[47]
Performance monitoring
[edit]The Infrastructure Act 2015 established the Office of Rail and Road (ORR) as the monitor for National Highways. ORR is responsible for monitoring and enforcing the performance and efficiency of National Highways, and advising the Secretary of State for Transport on its compliance against the Road Investment Strategy and Licence. The Act also established Transport Focus, previously Passenger Focus, as its watchdog, with the purpose of promoting and protecting the interests of users of the strategic road network.[46]
Traffic England
[edit]Traffic England is a website[48] that gives information about the latest traffic conditions as well as details of any roadworks or events that may cause congestion.[49] By selecting current motorway information users can see the average speed between individual motorway junctions, what is being displayed on all the variable-message signs, and images from traffic cameras.[49] The website is run by National Highways' National Traffic Information Service.
Survive Group
[edit]The Survive Group is a partnership between National Highways, the National Police Chiefs' Council, the breakdown/recovery industry and other road service providers. The Survive Group has been established to improve the safety of those who work on the road network and the travelling public and is dedicated to the promotion of driving safety. The name Survive comes from Safe Use of Roadside Verges in Vehicular Emergencies.
The Survive Group website holds information on the Survive Group membership details and activities being undertaken by the working groups. It supplies advice on how to drive safely in a wide range of driving conditions, advice on planning journeys. Survive provides publications and new guidance produced by the Survive members plus news on new initiatives and forthcoming road safety events.[50]
Historical Railways Estate
[edit]In 2013, Highways England took over responsibility for the Historical Railways Estate (HRE) from BRB (Residuary) Limited.[51]
Bridge infilling
[edit]Great Musgrave Bridge
[edit]
In May and June 2021, the space under the road bridge at Great Musgrave in Cumbria was filled with 1,600 tonnes of aggregate and concrete by Highways England, ostensibly for what HRE managers considered safety reasons. The bridge spanned a 5-mile (8.0 km) section of trackbed which local rail enthusiasts hoped to restore, linking the Eden Valley and Stainmore railways to create an 11-mile (18 km) tourist line between Appleby and Kirkby Stephen.[52][53]
Accused of 'vandalism', Highways England were forced to apply for retrospective planning permission,[54] with Eden District council receiving 913 objections and only two expressions of support,[55][56] and government intervention to pause National Highways plans to infill dozens of other Victorian bridges across England.[56] Advised by planning officers to reject the application,[55] the council's planning committee unanimously refused retrospective planning permission in June 2022.[57]
Restoration of the Musgrave bridge to its former condition would cost an £431,000, in addition to the £124,000 spent on the initial infilling work.[56] In July 2023, National Highways' plans to restore the bridge and remove the infill were criticised by locals as they involved closing the bridge for three months, necessitating long local diversions for regular users of the B6259 which crosses the bridge.[58] Work began in August 2023 to remove the infill material.[59]
After the Great Musgrave outcry, National Highways developed a new way to assess the abandoned rail bridges and tunnels it controls, with decisions reviewed in collaboration with experts from heritage, environmental and active travel sectors. The stakeholder advisory forum includes the Department for Transport, Sustrans, Railway Paths Ltd, Railway Heritage Trust, the HRE Group, Heritage Railway Association, Natural England, Historic England (also representing Cadw), Historic Scotland and ADEPT.[55]
Congham Bridge
[edit]In 2021, at Congham in Norfolk, a railway bridge designed by the pioneering M&GNJR engineer William Marriott was infilled by National Highways. The railway route had been identified as part of a proposed footpath and cycleway between King's Lynn and Fakenham, and in January 2023 King's Lynn and West Norfolk Borough Council demanded that National Highways submit a retrospective planning application.[60]
Rudgate Bridge
[edit]In 2021, an 1847 skewed masonry arch at Rudgate near Tadcaster, designed by John Cass Birkinshaw for the Harrogate–Church Fenton line, was infilled by National Highways. The agency had to seek retrospective planning approval from North Yorkshire Council for the infilling work and work on trees protected by a tree preservation order.[61]

National Highways
View on Grokipediafrom Grokipedia
National Highways is an executive non-departmental public body owned by the UK government and sponsored by the Department for Transport, tasked with operating, maintaining, and enhancing England's strategic road network (SRN), which spans approximately 4,500 miles of motorways and major A-roads.[1][2] This network, representing about 2% of England's total road length, carries roughly one-third of all road traffic by vehicle miles, underscoring its critical role in national connectivity and economic activity.[3]
Formed on 1 April 2015 as Highways England to replace the Highways Agency and grant greater operational independence, the organization was rebranded National Highways in August 2021 amid efforts to emphasize its national infrastructure mandate, though the change drew criticism for its estimated £7 million cost shortly after a prior rebranding.[4][5] Its establishment aligned with the government's Road Investment Strategy, which allocates multi-year funding for upgrades, safety enhancements, and capacity expansions to address congestion and support post-recession recovery.[4]
Key initiatives include the rollout of smart motorways, which convert hard shoulders into live running lanes controlled by variable speed limits and sensors to boost capacity without widening infrastructure; however, this program has sparked significant controversy due to documented technology failures, delayed response times to breakdowns, and elevated fatality rates on all-lane-running sections compared to conventional motorways with permanent hard shoulders, prompting the government to pause further conversions in 2022 and install additional emergency areas.[6][7][8] National Highways maintains that smart motorways are safer overall when accounting for traffic volume increases, citing lower collision rates per vehicle mile, though independent analyses and parliamentary inquiries have highlighted persistent risks from unreliable detection systems and insufficient refuge areas.[9][10]
Performance against these targets at RIS2's close showed mixed results, with 7 KPIs met, 4 missed, and one likely missed per ORR's July 2025 assessment; final safety data awaits STATS19 confirmation in autumn 2026. Achievements included exceeding efficiency savings at £2.2 billion, pavement condition at 96.5%, incident clearance at 88.7%, noise mitigation for 7,776 households, biodiversity net gain of 596 units, roadworks impact under cap at 41.8 million lane-metre-days, and air quality progress reducing non-compliant links to 19 despite external factors. Shortfalls encompassed a 39% KSI reduction (versus 50% target), average delay at 11.8 seconds per vehicle mile, 51% carbon reduction, 68.6% user satisfaction, and 74.1% roadworks notification accuracy. These outcomes reflect challenges like inflation, supply chain disruptions, and post-pandemic traffic patterns, though ORR noted overall delivery in context of external headwinds.[61][76]
History
Origins and Precursor Organizations
The centralized management of major arterial roads in England traces its modern origins to the early 20th century, when the Ministry of Transport, established in 1919, began coordinating national road improvements following the dissolution of the Road Board in 1919. The Road Board, created under the Roads Improvement Act 1910 (effective from 1911), had been tasked with funding and overseeing road construction and maintenance using vehicle excise duties and grants, marking an early shift toward national-level intervention in what had previously been largely local or trust-based responsibilities.[11] This body laid groundwork for systematic road classification, but its functions were absorbed by the Ministry amid post-World War I fiscal constraints and expanding motor traffic demands.[12] A pivotal development occurred with the Trunk Roads Act 1936, which designated over 3,000 miles of key inter-urban routes as trunk roads under direct central government control, relieving local authorities of primary responsibility while requiring them to act as agents for maintenance and operations. The Ministry of Transport thus became the custodian of this strategic network, funding improvements through national budgets and prioritizing connectivity for economic and military purposes; this system expanded post-1945 to include new trunk road schemes amid rising vehicle ownership.[12][13] By the 1950s, with the advent of motorways—beginning with the Preston Bypass in 1958—the Department of Transport (succeeding the Ministry in 1970 after departmental restructurings) managed the evolving motorway and trunk road portfolio, still largely via agency agreements with county councils for day-to-day upkeep.[14][15] These departmental structures served as the immediate precursors to a dedicated operational body, as growing network complexity—encompassing over 2,000 miles of motorways by the 1990s—highlighted needs for specialized delivery separate from policy-making. In this context, the Highways Agency was formed on 1 April 1994 as an executive agency of the Department of Transport, assuming direct responsibility for the operational, maintenance, and enhancement functions of the motorway and trunk road network previously handled internally by the Department's highways divisions. This transition aimed to enhance efficiency, accountability, and expertise in managing the strategic roads, which by then formed the core of England's national highway infrastructure.[14][16][17]Establishment as Highways Agency and Transition to Highways England
The Highways Agency was established on 30 March 1994 as an executive agency of the Department of Transport, assuming direct responsibility for operating, maintaining, and improving England's strategic road network of approximately 6,500 miles of motorways and trunk roads.[18][19] This creation followed the transfer of these functions from the Department itself, which had previously managed them internally, aiming to introduce agency-style operational autonomy while remaining accountable to ministerial oversight through framework documents and business plans.[20] By its inception, the Agency had already begun implementing key projects, such as enhancements to the network inherited from departmental initiatives, with annual reports documenting expenditures and performance metrics tied to government transport objectives.[21] Over the subsequent two decades, the Highways Agency operated under periodic framework agreements with the Department for Transport, focusing on network reliability, safety, and capacity amid growing traffic volumes that exceeded 150 billion vehicle miles annually by the early 2010s.[21] Criticisms emerged regarding short-term funding cycles that hindered long-range planning, prompting governmental review of road management structures to emulate more commercial, performance-driven models observed in utilities sectors.[22] The transition to Highways England occurred on 1 April 2015, when the Agency was reconstituted as a government-owned company limited by shares, incorporated on 8 December 2014 under the Companies Act 2006.[23][24] This reform, enacted via the Infrastructure Act 2015 and the Appointment of a Strategic Highways Company Order 2015, designated Highways England as the inaugural strategic highways company, granting it expanded operational independence from direct departmental control while retaining public ownership and regulatory oversight by the Office of Rail and Road.[25] The shift introduced multi-year Road Investment Strategies (RIS), starting with RIS1 allocating £15 billion for 2015–2020 to prioritize maintenance, congestion relief, and innovation, thereby mitigating the inefficiencies of annual budgeting that had previously constrained proactive investments.[4] Projected efficiencies from this structure included £2.6 billion in savings over the initial decade through streamlined procurement and performance incentives.[22]Rebranding to National Highways and Post-2021 Developments
On 20 August 2021, Highways England was rebranded as National Highways, marking the second name change for the organization within six years following its transition from the Highways Agency in 2015.[5] [26] The rebranding, first reported in October 2020, was estimated to cost £7 million and aimed to reflect a renewed focus on delivering the government's commitments for the strategic road network, though it did not expand the organization's geographical scope beyond England.[5] Critics described the move as "bizarre" given the absence of additional powers or responsibilities, emphasizing that the core functions remained unchanged.[27] Concurrently with the rebranding, Nick Harris was appointed as the new chief executive, replacing Jim O'Sullivan, to lead the organization into what was termed "a new era" for strategic roads management.[27] [28] In November 2021, National Highways announced a plan to accelerate the delivery of major road schemes by reducing development, design, and construction timelines, aiming to advance completion dates for projects under the second Road Investment Strategy (RIS2, 2020–2025).[29] Post-rebranding performance assessments for 2021–2022, the second year of RIS2, indicated strong overall delivery, with traffic levels on the strategic road network recovering to near pre-pandemic norms following the easing of COVID-19 restrictions.[30] [31] National Highways prioritized safety as its top objective in its 2021–2022 Delivery Plan Update, alongside customer service enhancements and RIS2 commitments, including the initiation of 10 major schemes.[32] In July 2021, shortly before the rebrand, the organization published its Net Zero Highways plan, outlining ambitions for carbon neutrality by 2030 for operations, 2040 for construction, and alignment with the UK's 2050 net zero target; annual progress reports since then have tracked advancements in fossil-free travel and zero-carbon practices.[33] [34] By 2025, as RIS2 neared completion, National Highways continued to emphasize efficiency and environmental goals amid ongoing consultations on future strategic road frameworks, though specific outcomes for RIS3 (post-2025) remained under development as of August 2025.[33]Organizational Structure
Governance Framework
National Highways functions as a government-owned company limited by guarantee and operates as an executive non-departmental public body sponsored by the Department for Transport (DfT). It was established as a strategic highways company under the Infrastructure Act 2015, effective from 1 April 2015, with primary accountability to the Secretary of State for Transport. The company's governance is outlined in a framework document that specifies roles, responsibilities, operational independence, and mechanisms for performance monitoring, ensuring alignment with national transport objectives while maintaining arm's-length management from direct government intervention.[35][36] The Board of Directors serves as the principal governance body, responsible for setting strategic direction, overseeing overall performance, reviewing principal risks, and appointing senior leadership. It ensures the long-term success of the organization through annual reviews of the Delivery Plan and adherence to the Strategic Business Plan. Day-to-day operations are delegated to the Chief Executive Officer, supported by Executive Directors who implement board-approved strategies and manage functional areas such as finance, safety, and network operations. This structure promotes efficient decision-making while upholding fiduciary duties under corporate law.[35] External oversight is provided by the Office of Rail and Road (ORR), which monitors National Highways' efficiency and performance against objectives in the Road Investment Strategy (RIS), including annual assessments of network management, safety, and investment delivery. Established under 2015 roads reform legislation, the ORR enforces accountability through public reporting, advice to the DfT on future funding, and potential enforcement actions for non-compliance. The Secretary of State issues strategic directions via a formal licence, tying performance to multi-year RIS periods that specify funding and targets for the strategic road network.[37][35]Leadership and Headquarters
National Highways maintains its registered office and headquarters at Bridge House, 1 Walnut Tree Close, Guildford, Surrey, GU1 4LZ, from which strategic and administrative functions are primarily directed.[38] The organization also operates key facilities including the National Traffic Operations Centre at 3 Ridgeway, Quinton Business Park, Birmingham B32 1AF, supporting real-time network monitoring and incident response.[39] Leadership is provided by a Board of Directors, chaired by Gareth Rhys Williams, who oversees governance and strategic direction while ensuring accountability to the UK Department for Transport.[40] Nick Harris serves as Chief Executive, responsible for day-to-day operations, delivery of the Road Investment Strategy, and execution of network improvements across England.[40] The Board comprises non-executive directors offering independent oversight, with recent additions including Kim Shillinglaw, appointed as a Non-Executive Director effective 10 February 2025, bringing expertise in media and public sector delivery.[41] The Executive Team, reporting to the Chief Executive, includes directors such as Scott Dale for finance and Swati Paul, appointed Executive Director and General Counsel on 28 July 2025, who advises on legal and regulatory matters.[40][42] This structure delegates operational authority from the Board to the executive leadership, aligning with corporate governance principles that emphasize clear separation of responsibilities.[35]Regional and Operational Teams
National Highways structures its operations across seven regions—North West, North East, East Midlands, West Midlands, Yorkshire and North East, East, and South West & London—each overseeing designated segments of the strategic road network to facilitate localized management and response capabilities.[43] These regions enable targeted oversight of maintenance, incident handling, and investment activities, with performance metrics benchmarked annually to ensure accountability and efficiency.[44] At the core of regional operations are seven Regional Operations Centres (ROCs), one per region, which function 24/7 to monitor traffic conditions, coordinate incident responses, dispatch resources, and liaise with external partners such as police, emergency services, and recovery operators.[45] ROC teams integrate real-time data from the National Traffic Operations Centre to implement traffic management strategies, including lane closures and diversions, minimizing disruptions across approximately 4,500 miles of motorways and major A-roads.[45][46] Operational teams on the ground comprise Traffic Officers and Inspectors, who execute frontline duties under regional direction. Traffic Officers act as initial responders to incidents, clearing obstructions, aiding stranded vehicles, and enforcing temporary traffic controls in coordination with law enforcement, thereby enhancing network resilience during peaks such as the 33-hour amber weather alerts issued for severe conditions affecting multiple regions.[45] Inspectors conduct routine patrols to identify structural defects, monitor assets like bridges and embankments, and prioritize repairs, supporting proactive maintenance to uphold safety standards.[45] To standardize practices, National Highways introduced a unified organizational framework for regional teams during the 2020-2025 period, emphasizing consistent protocols for operations, safety, and performance measurement across regions.[47] This structure fosters collaboration between regional centres and area-based sub-teams, which handle granular tasks like infrastructure inspections and event-specific traffic management, ultimately contributing to reliable network performance amid varying regional demands such as urban congestion in the South East or rural connectivity in the North West.[48]Workforce and Partnerships
National Highways maintains a workforce of approximately 6,800 full-time equivalent employees as of mid-2025, focused on roles in network operations, asset management, engineering, and project oversight across England's strategic road network.[49] [50] This staffing level supports daily maintenance, incident response, and major infrastructure programs, with employees distributed across regional teams and headquarters functions. The organization reports average sick leave of 11.7 days per worker annually, contributing to operational challenges amid an aging network.[50] To address workforce capabilities, National Highways implements training programs, including online modules on equality, diversity, and inclusion (EDI), as well as specialized sessions on inclusive leadership and communication.[51] [52] These efforts aim to enhance decision-making and retention, though sector-wide data indicates high turnover, with 62.3% of leavers from surveyed firms exiting the highways industry entirely in 2024.[53] The company publishes annual gender pay gap reports, reflecting commitments to inclusive practices while acknowledging disparities in representation.[54] Partnerships form a core element of operations, with National Highways engaging a broad supply chain for procurement, construction, and technical services. Key frameworks include the £1.3 billion Pavement Delivery Framework, uniting 12 suppliers for resurfacing and maintenance works since 2022.[55] The Specialist Professional and Technical Services 3 (SPaTS3) framework, valued at £495 million, appoints multiple suppliers for advisory and delivery support through 2030.[56] Additionally, the extended £8.7 billion Delivery Integration Partner program coordinates major projects across regions, involving consortia like those led by firms such as AECOM for infrastructure delivery.[57] [58] These collaborations extend to social enterprises via a dedicated supplier directory and the Supplier Development System, which assesses and builds competencies in areas like sustainability and social value.[59] [60] Oversight bodies, including the Office of Rail and Road, monitor performance, while direct ties to the Department for Transport ensure alignment with national priorities.[61] This model leverages external expertise to manage the 7,500 km network efficiently, though dependency on contractors has drawn scrutiny over cost controls and delivery timelines in annual assessments.[62]Responsibilities
Network Operation and Maintenance
National Highways is responsible for the operation and maintenance of England's Strategic Road Network (SRN), encompassing over 4,500 miles of motorways and major A-roads that facilitate the movement of approximately one-third of the nation's vehicular traffic.[46] [63] Operation entails real-time monitoring and management to ensure safety and fluidity, while maintenance focuses on preserving asset integrity through inspections, repairs, and renewals to mitigate deterioration from heavy usage.[6] These activities are guided by performance specifications under Road Investment Strategies, prioritizing resilience against weather, wear, and incidents.[64] Traffic operation relies on advanced surveillance via thousands of CCTV cameras, loop detectors, and weather sensors integrated into Regional Control Centres, which coordinate responses to congestion or disruptions using variable message signs, electronic signage, and smart motorway technology.[65] Traffic Officers, deployed in highly visible vehicles, serve as the primary on-scene responders, implementing temporary measures such as contraflows, speed restrictions, or rolling roadblocks to secure areas and expedite clearance under the CLEAR protocol, which emphasizes quick detection, response, and traffic restoration.[45] [66] This approach has reduced average incident clearance times, though challenges persist with peak-hour volumes exceeding 170,000 vehicles daily on key routes.[67] Maintenance encompasses routine cyclical works, including verge cutting, gully cleaning, and structural inspections to address defects like potholes or barrier damage before they escalate risks.[64] Renewals involve large-scale interventions, such as pavement resurfacing and bridge reinforcements, supported by £10.8 billion allocated for 2020-2025 to extend asset life amid an aging network where many structures date to the mid-20th century.[68] National Highways outsources much of this to regional contractors under Maintenance and Response frameworks, with forthcoming £9.6 billion contracts from 2025 aiming to enhance efficiency through data-driven predictive maintenance via operational technologies like AI analytics and drone inspections.[69] [70] Performance is monitored by the Office of Rail and Road, which assesses metrics including road surface condition index and incident response efficacy, revealing steady improvements but ongoing needs for investment in resilience against climate impacts.[67]Improvement and Expansion Projects
National Highways manages a portfolio of improvement and expansion projects aimed at enhancing capacity, safety, and resilience on England's Strategic Road Network, primarily through the second Road Investment Strategy (RIS2) spanning April 2020 to March 2025.[71] RIS2 allocated £27.4 billion overall, with significant portions directed toward road enhancements, including the delivery of 52 schemes intended to save 20 million vehicle hours annually and generate £27 billion in socioeconomic benefits.[72] These projects encompassed widening existing routes, junction improvements, and technology integrations to address congestion and support economic growth, though execution faced headwinds from inflation, supply disruptions, and policy shifts.[73] By the conclusion of RIS2 in March 2025, National Highways had opened 30 major enhancement schemes to traffic, with 11 additional projects under construction, falling short of initial targets including 11 planned enhancements deferred due to cost pressures and external factors.[74][75] The National Audit Office reported that overall road enhancement work was reduced in scope and executed at higher costs than originally budgeted, reflecting adjustments made early in the period to prioritize viability amid rising material prices and labor shortages.[73] In the final year (2024/25), seven schemes were completed, aligning with meeting 7 of 12 key performance indicators as assessed by the Office of Rail and Road.[76] Smart motorways represented a core improvement initiative under RIS2, deploying variable speed limits, emergency refuge areas, and all-lanes-running configurations to boost throughput equivalent to adding lanes without physical expansion; six projects already underway were completed despite the program's challenges.[77] However, empirical data indicated elevated incident rates—such as breakdowns and collisions—on sections lacking permanent hard shoulders, eroding driver confidence and prompting the government to halt all new smart motorway developments in April 2023.[78] To mitigate risks, the National Emergency Area Retrofit (NEAR) program added hundreds of refuge areas to existing dynamic hard shoulder sections, enhancing breakdown safety.[75] Expansion efforts included targeted widenings and upgrades, such as the M6 junction 21a to 26 scheme, which added capacity over 10 miles through lane additions and junction enhancements, with works concluding in August 2025 to reduce congestion in the West Midlands.[79] The A14 Cambridge to Huntingdon dualling project improved freight access to the Port of Felixstowe, alleviating local bottlenecks upon completion.[72] Other examples encompassed resilience-focused upgrades like the A303 Amesbury to Berwick Down, incorporating tunnels to bypass sensitive areas while expanding dual-carriageway sections. Delays affected schemes such as M25 junction 10 improvements and the A63 Castle Street upgrade, rescheduled beyond 2025 due to planning complexities.[75] Beyond RIS2, National Highways invests £347 million in developing a pipeline of potential future expansions, evaluating schemes for economic justification, environmental impact, and integration with rail and active travel modes, with decisions pending RIS3 formulation.[80] Innovations like the UK's first carbon-neutral carriageway reconstruction in Cumbria demonstrate efforts to align expansions with net-zero goals, using low-emission materials in an £8 million project.[81]Traffic Information and Incident Management
National Highways delivers real-time traffic information via the Traffic England platform, which supplies live data on traffic speeds, flow conditions, and disruptions across England's strategic road network.[82] The platform integrates feeds from over 8,000 CCTV cameras, inductive loops for speed detection, and automatic number plate recognition to monitor and report conditions continuously.[45] The National Traffic Operations Centre (NTOC) in Birmingham provides 24/7 strategic oversight, coordinating information dissemination through variable message signs (VMS), social media channels, RSS feeds, and the Traffic England website to alert drivers of incidents, roadworks, and congestion.[45] Seven regional control centres support this by handling local monitoring, emergency calls from roadside telephones, and initial incident assessments, ensuring rapid updates to maintain network performance.[45] Incident management emphasizes quick detection, response, and clearance to minimize delays and enhance safety.[66] Traffic officers, deployed from regional teams, serve as first responders on the scene, implementing emergency traffic management such as lane closures and rolling roadblocks to secure areas and facilitate recovery operations.[45] Established in 2004 under the Traffic Management Act, these officers possess statutory powers to stop or direct traffic, remove obstructions, and enforce vehicle movement when necessary to restore flow, working in coordination with police and contractors.[83] [45] Responses adhere to the CLEAR protocol, a structured framework for multi-agency collaboration that involves communicating risks, locating the incident, evaluating options, acting decisively, and reviewing outcomes to keep traffic moving efficiently.[66] The traffic officer service has expanded significantly since inception, growing tenfold by 2024 to handle over 500,000 incidents annually, including breakdowns, debris, and collisions.[84] The customer contact centre processes approximately 30,000 calls and 7,000 emails monthly, providing incident-specific advice and forwarding reports to operational teams.[45]Strategic Road Network
Scope and Coverage
The Strategic Road Network (SRN) encompasses England's motorways and major trunk A-roads, totaling over 4,500 miles (7,242 km) as of 2025.[46][2] This includes all 2,300 miles of motorway and approximately 2,200 miles of high-standard A-roads designated for national strategic importance, such as the A1, A30, A303, and A40.[3] The network excludes local authority roads, those in London, Scotland, Wales, and Northern Ireland, as well as minor A-roads managed by local councils.[46] Despite comprising only about 2% of England's total public road length of roughly 245,000 miles, the SRN carries approximately one-third of all passenger vehicle miles and two-thirds of heavy goods vehicle miles annually.[33][3] In 2024, it handled over 4 million vehicles daily, underscoring its role in freight logistics and personal mobility.[22] Following the expiry of Design, Build, Finance, and Operate (DBFO) contracts in 2025, approximately 10% more road length—primarily additional motorway and A-road segments—will transfer to direct National Highways management, expanding operational scope without altering the core designation.[61] Geographically, the SRN provides backbone connectivity across England, linking key population centers like London, Birmingham, Manchester, and Leeds; economic regions such as the Midlands and the South East; and international gateways including major ports (e.g., Dover, Felixstowe, Liverpool) and airports (e.g., Heathrow, Gatwick).[33] It facilitates radial and orbital routes for inter-urban travel, supporting economic activity by enabling efficient movement of people and goods while integrating with regional transport via junctions to local roads.[85] This coverage prioritizes high-capacity corridors critical for national supply chains, with design emphasizing resilience against disruptions like congestion or weather events.[22]Design Standards and Safety Features
The design of England's Strategic Road Network (SRN), managed by National Highways, adheres to the Design Manual for Roads and Bridges (DMRB), a comprehensive set of standards and guidance documents that specify requirements for the geometric layout, cross-sections, and operational aspects of motorways and trunk roads.[86] The DMRB ensures alignment with safety, capacity, and durability objectives, drawing from empirical research and operational experience to minimize accident risks through controlled curvature, visibility, and pavement design. For motorways, standard traffic lane widths are 3.65 meters, with provisions for wider lanes (up to 4 meters or more) in high-speed or high-volume sections to accommodate heavy goods vehicles and reduce lateral friction.[87] Horizontal and vertical geometry follows design speeds typically ranging from 120 km/h (75 mph) on newer alignments to 100 km/h (62 mph) on constrained routes, with minimum radii and gradients calibrated to prevent loss of control based on vehicle dynamics and braking distances.[86] Safety features on the SRN incorporate physical and technological elements to mitigate collision risks, including central reserve barriers—often steel beam or wire rope systems—to prevent cross-median crashes, which account for a significant portion of fatal incidents.[88] Lighting is mandatory on complex interchanges and tunnels, with high-mast installations providing uniform illumination to reduce nighttime visibility hazards, while reflective road studs and markings enhance lane discipline. Variable message signs and gantries enforce dynamic speed limits, adjusting to traffic density or weather to maintain safe headways.[88] A prominent evolution in SRN safety is the deployment of smart motorways, where the hard shoulder is eliminated in all-lanes-running (ALR) configurations to increase capacity, supplemented by emergency refuge areas spaced at intervals of no more than 1 mile (ideally 0.75 miles), each at least 4.6 meters wide and equipped with emergency telephones linked to control centers.[89] Stopped vehicle detection (SVD) technology, using radar and cameras, identifies breakdowns within approximately 20 seconds, automatically closing lanes via overhead signals and alerting traffic officers for rapid response.[89] National Highways reports that smart motorways exhibit lower rates of deaths and serious injuries compared to conventional motorways, attributing this to smoother traffic flow and enforcement measures, with recent upgrades including over 700 additional signs and enhanced cameras completed by March 2025.[9][90] However, independent analyses, such as a December 2023 National Highways report, indicate that breakdowns on ALR smart motorways carry a threefold higher risk of fatality or serious injury relative to traditional designs, prompting ongoing debates over refuge area density and technology reliability despite mitigation efforts like the addition of over 150 new emergency areas by March 2025.[91][92]Integration with Broader Transport System
The Strategic Road Network (SRN), managed by National Highways, interfaces with the broader UK transport system primarily through junctions and connectors to local authority roads, which handle the majority of urban and rural access points. Local authorities maintain these adjoining roads, requiring coordination for traffic management, signage, and safety enhancements at boundaries, such as real-time congestion monitoring and joint incident response protocols.[46][93] This setup ensures continuity but can lead to bottlenecks where high-volume SRN traffic merges with lower-capacity local networks, prompting collaborative upgrades like improved junction signaling.[94] The SRN provides critical links to intermodal facilities, including direct access to major ports, airports, and the Channel Tunnel, facilitating 75% of UK imports and exports transported by road as of 2021, with 70% of heavy goods vehicle (HGV) movements occurring on the network.[95] It integrates with rail networks through shared freight corridors and passenger access points, supporting multimodal hubs like the "Golden Triangle" logistics area, where road haulage complements rail freight carrying 91 million tonnes annually compared to road's 1,900 million tonnes in 2015.[95] Inland waterways and coastal shipping also connect via SRN feeders, enabling efficient goods transfer and reducing reliance on single modes for long-haul logistics.[95] National Highways pursues multi-modal integration via its long-term vision for a seamlessly connected system by 2050, emphasizing coordination with entities like Network Rail to enhance gateways and support net-zero goals through diversified freight options.[96] Sustainability initiatives include programs to bolster public transport operations on the SRN, such as bus lane provisions and park-and-ride facilities at key junctions, alongside promoting active travel modes like cycling and walking via network-adjacent paths and accessibility improvements.[97][98] These efforts aim to mitigate road dominance by encouraging modal shifts, though empirical data shows road remains predominant for freight due to its flexibility and capacity.[95]Funding and Investment
Road Investment Strategies (RIS1 and RIS2)
The first Road Investment Strategy (RIS1) spanned from April 2015 to March 2020 and committed £15.2 billion to Highways England for capital and resource investment in England's strategic road network.[99] This five-year settlement marked a shift to long-term funding stability, enabling proactive planning over annual budgets, with objectives centered on delivering smooth, smart, and sustainable roads through over 100 major schemes for enhancements, renewals, and improvements.[99] Key targets included adding more than 1,300 lane miles of additional capacity, implementing safety measures to avert over 2,500 deaths or serious injuries, improving 200 sections for cyclists and pedestrians, and reducing noise impacts for up to 250,000 people via targeted interventions like noise barriers.[99] The strategy also mandated efficiencies of at least £1.2 billion over the period to reinvest in further network upgrades.[100] The second Road Investment Strategy (RIS2), covering April 2020 to March 2025, allocated £27.4 billion to National Highways (formerly Highways England) for operations, maintenance, renewals, and enhancements to the strategic road network.[71] It extended RIS1's framework by incorporating a 2050 vision for the network, emphasizing resilience, customer service, and integration with broader transport goals, while setting updated performance specifications monitored by the Office of Rail and Road.[71] Investments prioritized asset renewals and major enhancements, including £12.8 billion specifically for maintenance, renewals, and operational costs, alongside initiatives for environmental mitigation such as biodiversity enhancements and reduced emissions.[71] [101] RIS2 introduced designated funds for targeted areas like air quality and innovation, with a central risk reserve of around £1.4 billion to address unforeseen issues, though subsequent adjustments reduced overall funding to approximately £23 billion amid fiscal pressures.[71] [76] Compared to RIS1, RIS2 expanded scope to include greater emphasis on long-term sustainability and technology integration, such as smart motorways and data-driven asset management, while maintaining the core principle of ring-fenced, multi-year funding to minimize short-term political interference in project delivery.[71] Both strategies aimed to address congestion and safety on approximately 4,500 miles of motorways and trunk roads, but RIS2 incorporated lessons from RIS1's delivery, including enhanced accountability mechanisms and a broader economic justification linking investments to GDP growth and job creation.[71] [102]Financial Challenges and Allocations
The second Road Investment Strategy (RIS2), covering 2020 to 2025, initially allocated £27.4 billion to National Highways for managing and improving England's strategic road network, with approximately £14.1 billion designated for road enhancements and the remainder for operations, maintenance, and renewals.[103] Subsequent government adjustments, prompted by fiscal constraints and high inflation, reduced the overall budget to £24 billion, including a cut in enhancement funding to £10.5 billion, requiring National Highways to reprioritize projects and achieve efficiencies.[104] Key financial challenges during RIS2 included persistent inflation in construction costs, which eroded purchasing power and contributed to cost overruns on multiple schemes; for instance, six of nine major projects under construction at the period's close were both delayed and over budget, as measured by earned value metrics from the Office of Rail and Road (ORR).[75] Delays in planning decisions and regulatory approvals further compounded pressures, leading to uncertainty in expenditure and a failure to meet 11 of 48 enhancement commitments.[105][106] In response, National Highways delivered £2.2 billion in efficiencies over RIS2, falling short of the original £2.304 billion target but adapting to mid-period funding reductions by curtailing non-essential activities and optimizing resource allocation.[107] Allocations emphasized renewals and maintenance, with critics noting an imbalance where enhancement spending received priority early on, though actual outturns reflected constrained fiscal realism amid broader economic headwinds rather than agency inefficiency alone.[108] Funding for the final year of RIS2 remained unconfirmed until September 2024, leaving the agency in a protracted state of budgetary limbo that hindered long-term planning.[109]Sources of Funding and Economic Justification
National Highways receives its primary funding through grants from the Department for Transport (DfT), which are allocated via the Road Investment Strategy (RIS) in five-year cycles known as Road Investment Periods (RPs).[110][111] These grants originate from the National Roads Fund (NRF), a hypothecated fund drawing revenues from Vehicle Excise Duty (VED) collected in England.[112][49] For Road Period 2 (RP2, 2020–2025), the RIS2 provided an investment envelope of £27.4 billion, enabling operations, maintenance, and enhancements to the Strategic Road Network (SRN).[113][71] The overall NRF allocation for 2020–2025 totaled £28.8 billion, supporting national road improvements including those managed by National Highways.[112] Funding levels are set by HM Treasury and Parliament, with adjustments possible via spending reviews; for instance, the 2021 Spending Review reduced allocations by £3.428 billion due to scheme revisions.[61] Supplementary revenues, such as from tolled sections of the SRN, contribute marginally but are not the core mechanism.[111] Economic justifications for SRN investments emphasize the network's role in facilitating national productivity and connectivity, with official assessments highlighting returns exceeding costs through reduced travel times, lower congestion, and enhanced freight efficiency.[114][115] The SRN links major urban centers, ports, airports, and the Channel Tunnel, supporting supply chains, labor mobility, and international trade while enabling business clustering and regional development.[33][114] Investments are evaluated via cost-benefit analyses prioritizing high-demand corridors, where improvements yield agglomeration effects and broader economic multipliers, such as GDP contributions estimated in billions annually from reliable connectivity.[115][116] For RP2, National Highways' analysis projected £26.7 billion in total value benefits, underscoring high return on investment through operational efficiencies and growth facilitation, though independent critiques have questioned the magnitude of induced demand and spillover effects in some schemes.[117][118] RIS3 planning (2025–2030) continues this framework, targeting inflation-adjusted funding to sustain these outcomes amid fiscal constraints.[119]Performance and Achievements
Key Performance Indicators (KPIs) and Targets
National Highways operates under the second Road Investment Strategy (RIS2, covering April 2020 to March 2025), which establishes 12 Key Performance Indicators (KPIs) defined by the Department for Transport to measure progress across core outcome areas including safety, journey reliability, network maintenance, environmental impacts, user satisfaction, and operational efficiency. These KPIs are tracked via the Operational Metrics Manual, using data from sources such as STATS19 casualty reports, traffic surveys, asset inspections, and emissions inventories, with annual assessments by the Office of Rail and Road (ORR). Targets are ambitious, aiming for quantifiable reductions or thresholds, often benchmarked against historical baselines like the 2005-2009 period for safety metrics.[120][61] The KPIs and their RIS2 targets are outlined below:| Outcome Area | KPI | Target |
|---|---|---|

| User needs | Roadworks information timeliness and accuracy | 75% of overnight closures notified accurately 7 days in advance by 2024-25 (revised from initial 90%)[120] |
| Efficiency | Total efficiency savings | £1.99 billion in capital and operational expenditure by end of RIS2[120] |
Major Completed Projects
During the second Road Investment Strategy period (RIS2, 2020–2025), National Highways opened 30 major enhancement schemes to traffic, focusing on increasing road capacity, reducing congestion, and enhancing safety across England's strategic road network.[121] These projects included junction improvements, road widenings, and smart motorway upgrades, delivering benefits such as shorter journey times and better connectivity to economic hubs like ports and airports.[72] Notable completed schemes encompassed:- A585 Windy Harbour to Skippool (2024): This dualling project in Lancashire improved flood resilience and traffic flow on a key route to Fleetwood, reducing delays for local communities and businesses.[122]
- A30 Chiverton to Carland Cross (2024): Dualling of 1.7 miles (2.7 km) in Cornwall alleviated bottlenecks near Newquay, supporting tourism and cutting peak-hour queues by up to 30 minutes.[122]
- M6 Junctions 21a to 26 smart motorway (2024): Addition of variable speed limits and hard shoulder running between Cheshire and Greater Manchester increased capacity by 40% on a heavily used freight corridor.[122]
- A46 Coventry Junctions at Binley (2023): Upgrades to signalised junctions enhanced access to the Midlands' manufacturing base, improving safety and reducing collision risks.[122]
- M25 Junction 25 improvement (2022): Enlarged roundabout and additional lanes near the M11 eased merging issues on London's orbital motorway, benefiting over 200,000 daily users.[122]

National Highways has implemented over 570 safety schemes during Roads Period 2 (2020-2025), targeting high-collision A-roads with enhancements such as improved signage, road markings, pedestrian crossings, and speed management measures to mitigate risks.[123] These initiatives contributed to a 39% reduction in killed or seriously injured (KSI) casualties on the strategic road network (SRN) in 2023, totaling 1,913 KSIs, compared to the 2005-2009 baseline average, though this fell short of the 50% reduction target set for 2025.[124] Overall, KSI incidents on the SRN have followed a long-term downward trend, with the latest data recording the fewest such casualties to date, reflecting sustained investments in infrastructure like barriers and lighting.[61] Smart motorways represent a core strategy for both safety and efficiency, utilizing technology such as variable speed limits, dynamic hard shoulder use, and all-lane running (ALR) to manage traffic flow. Safety data from 2018 to 2022 indicates that all types of smart motorways—controlled, dynamic hard shoulder, and ALR—exhibit lower rates of fatalities and serious injuries than conventional motorways, with 37 out of 39 schemes showing improved performance post-implementation.[125] To address breakdown risks, National Highways installed over 700 additional refuge area signs indicating emergency stopping distances and deployed radar-based stopped vehicle detection across all ALR sections by March 2025, completing key upgrades mandated after the 2020 government action plan.[90] While some analyses highlight elevated dangers during breakdowns—claiming three times the risk compared to traditional setups—aggregate collision statistics from official sources consistently demonstrate net safety gains.[126][91] On efficiency, smart motorways enhance network capacity without the need for physical widening, which disrupts traffic and increases environmental costs, by converting hard shoulders into active lanes during peak demand.[127] This approach has reduced congestion on busy corridors through real-time traffic management, enabling smoother flow and minimizing delays; for instance, variable speed enforcement and lane control have lowered average journey times on upgraded sections.[128] Broader efficiency efforts in RP2 included optimizing roadworks to limit network disruption, with weighted lane-metre days of closures averaging below strategic targets, thereby sustaining freight and commuter reliability amid growing demand.[129] These measures align with performance indicators showing progressive improvements in journey time reliability, though full realization depends on ongoing technological integration like advanced analytics for predictive maintenance.[108]Criticisms and Controversies
Operational and Delivery Shortfalls
During the second Road Investment Strategy (RIS2) period from April 2020 to March 2025, National Highways failed to meet several key performance indicators (KPIs), including average delay per vehicle per mile, which rose to 11.8 seconds against a target of 9.5 seconds, contributing to increased congestion and economic costs for users.[61][76] The organization met only 7 of 12 operational KPIs overall, with shortfalls in road user satisfaction (68.6% versus 71%), timeliness of roadworks information (74.1% versus 75%), and corporate carbon emissions reduction (51% versus 56%).[61] Technology availability for operational systems fell to 90%, below the internal target of 95%, exacerbating issues like unreliable detection of stationary vehicles on smart motorways.[61] Project delivery under RIS2 saw significant shortfalls, with 11 enhancement commitments missed due to supply chain disruptions, inadequate asset data, and internal planning failures, alongside 20 schemes cancelled, including parts of the A303 Amesbury to Berwick Down project.[61] Expenditure on enhancements totaled £8.9 billion, well below the original £13.3 billion forecast, following a £3.4 billion (27%) budget reduction prompted by delays and cost pressures from inflation exceeding initial projections.[61][73] Specific delays affected major schemes, such as the M25 Junction 10 improvement and A63 Castle Street upgrade, both postponed to 2026 due to unforeseen ground conditions and utility conflicts.[61] Renewals outputs also underperformed, missing two of five commitments, including 14 lane kilometers of concrete pavement reconstruction and 16% of concrete safety barriers, partly from the M27 Junctions 5-7 scheme overrun.[61] These shortfalls stemmed from a mix of external factors, such as 89 government-directed programme changes, legal challenges to planning consents, and high inflation, alongside internal issues like poor risk forecasting and non-compliance with data provision requirements under the operating licence.[61][73] The National Audit Office highlighted inadequate initial risk assessment for the complex portfolio of 69 enhancement projects, leading to less work completed at higher costs and diminished value for money.[73] Asset resilience lagged, with drainage systems at 72% effectiveness and a 33% rise in urgent defects signaling deterioration that could worsen delays.[61] The Department for Transport expressed concerns over escalating delays, which added 0.7 seconds per vehicle mile from the National Highways' Emergency Areas and Response (NEAR) programme roadworks, prompting a mandated Customer and Delay Action Plan for 2025/26.[76] Safety targets remained off-track, with only 39% progress toward a 50% reduction in killed or seriously injured incidents by December 2025.[61]Environmental and Planning Disputes
National Highways' road enhancement projects under the Roads Investment Strategy have frequently encountered environmental and planning disputes, primarily through judicial reviews and public protests, resulting in delays and escalated costs estimated at £66 million to £121 million per affected scheme due to construction halts and redesigns.[130] These challenges, often initiated by environmental advocacy groups, cite inadequate assessments of greenhouse gas emissions, habitat disruption, and cumulative environmental impacts, though courts have upheld approvals in approximately 87% of cases since 2008.[130] The A303 Stonehenge tunnel project exemplified protracted planning battles, with opponents arguing that the scheme's environmental impact assessment unlawfully omitted cumulative carbon emissions from related road developments and risked irreversible damage to archaeological landscapes within the World Heritage Site.[131] Initially approved in 2020, the Development Consent Order (DCO) was quashed by the High Court in 2021 for procedural flaws in environmental evaluation, prompting re-approval in 2023 after revisions.[131] Campaigners secured permission for a further judicial review in 2024, but the Court of Appeal later determined the Department for Transport's decision was lawful; the project was ultimately canceled in July 2024 by the incoming Labour government citing fiscal constraints, with revocation of the DCO initiated in October 2025, incurring sunk costs exceeding £180 million.[131][132][133] Similar contentions arose in the Lower Thames Crossing proposal, where objectors contested the planning process for underestimating induced traffic growth and associated carbon emissions, alongside habitat loss in Essex and Kent.[134] After a multi-year examination involving over 350,000 pages of documentation and costing nearly £300 million, planning consent was granted in March 2025 following government intervention to resolve election-related delays.[130][135] Broader criticisms have targeted National Highways' handling of carbon footprints, with corporate emissions rising in 2023 despite net-zero pledges, and legal actions alleging failures to quantify scheme-induced emissions under the Climate Change Act 2008.[136] Courts have rejected several such claims, as in the 2024 Court of Appeal dismissal of a cumulative emissions challenge against multiple schemes, affirming that project-specific assessments suffice absent evidence of systemic oversight gaps.[137] Advocacy groups have also accused the organization of advancing sub-£500 million projects without sufficient ministerial scrutiny, relying on internal business cases that allegedly prioritize construction over updated emissions modeling.[138] Operational disruptions from environmental activism, such as Just Stop Oil's motorway blockades, prompted National Highways to secure injunctions in 2022 prohibiting interference with the M25, reflecting tensions between protest rights and network reliability.[139] National Highways officials have voiced frustration over the proliferation of challenges—five of seven DCO approvals in 2023 faced litigation—attributing them to procedural nitpicking rather than substantive flaws, which inflate taxpayer burdens without commensurate environmental gains.[140]Accountability and Regulatory Scrutiny
National Highways operates under a regulatory framework established by the Infrastructure Act 2015, which designates the Office of Rail and Road (ORR) as the independent economic and safety regulator responsible for monitoring its performance, efficiency, and compliance with the Road Investment Strategy (RIS).[141] The ORR assesses National Highways against key performance indicators (KPIs) in areas such as safety, asset management, traffic management, and project delivery, publishing annual reports that evaluate progress and identify shortcomings.[61] These assessments inform incentives and penalties tied to funding allocations, ensuring accountability for taxpayer-funded operations of the strategic road network.[142] In February 2024, the ORR initiated a formal investigation into National Highways' compliance with its license obligations and RIS2 commitments, focusing on deficiencies in data reporting, governance, and delivery assurance across six key areas including program management and stakeholder engagement.[143] The investigation concluded in June 2024, prompting National Highways to submit a comprehensive improvement plan in September 2024, which included commitments to enhance data quality, timeliness of information to the ORR, and internal capabilities for better regulatory compliance.[144] A six-month update in March 2025 reported progress in implementing these measures, such as improved reporting processes and support for ORR's annual safety assessments.[145] The Department for Transport (DfT) provides additional oversight through annual performance reports to Parliament, evaluating National Highways against strategic objectives set in the Performance Specification.[146] For the 2024-2025 reporting year, the DfT's assessment highlighted mixed results, with achievements in operational efficiency but ongoing challenges in project delivery and resilience.[76] The ORR's corresponding 2024-2025 annual assessment acknowledged efficiency savings and key project completions under RIS2, despite 11 missed enhancements and noted risks to network resilience, emphasizing the need for sustained improvements in delivery confidence.[61][75] Parliamentary scrutiny is facilitated through the DfT's reports and ORR's public dashboards, which provide transparent data on outcomes like incident response times and asset conditions, enabling democratic accountability.[147] While the framework promotes evidence-based regulation, critics have argued that the ORR's monitoring could be strengthened by incorporating broader performance metrics beyond financial efficiency, such as user satisfaction and environmental impacts.[148] National Highways remains ultimately accountable to the Secretary of State for Transport, with the potential for license modifications or interventions if systemic failures persist.[107]Future Plans
RIS3 (2025-2030) Objectives
The third Road Investment Strategy (RIS3), covering the period from April 2026 to March 2031 (commonly referred to as the 2025-2030 road period), establishes the government's priorities for England's Strategic Road Network (SRN), administered by National Highways, with a total funding envelope of £24,983 million as outlined in the Statement of Funds Available.[149] This strategy emphasizes sustaining and enhancing the 4,500-mile network, valued at £156.1 billion, through targeted investments in operations, maintenance, and renewals, which comprise approximately 43% of the RIS2 budget precedent and are expected to continue proportionally.[149] Core strategic themes include fostering economic growth to support £409.7 billion in gross value added (GVA), projected to rise to £578 billion by 2050; improving network performance via reliability enhancements and delay reductions; and building resilience against climate change and infrastructure aging.[149][2] Safety remains a paramount objective, aiming for zero harm by 2050, including a 50% reduction in killed and seriously injured (KSI) incidents from the 2005-2009 baseline, while preserving the UK's ranking as the fifth safest road network globally.[149] National Highways plans to upgrade 50% of 1- and 2-star rated roads (totaling 1,458 miles under the international Road Assessment Programme) to at least 3-star standards, alongside measures like 8,000 miles of safety barriers and suicide prevention initiatives.[2] Environmental goals align with net zero targets, mandating 100% electric light fleet operations by 2030, a 40-50% cut in construction and maintenance emissions by 2030, and full decarbonization of operations by 2030, construction emissions by 2040, and user travel by 2050.[2][149] Biodiversity enhancements target a 10% net gain, including planting 3 million trees by 2030 and over 400 hectares of woodland in projects like the Lower Thames Crossing.[2] Network efficiency and customer service objectives focus on proactive renewals, such as resurfacing 4,660 miles of asphalt and 78 miles of concrete, alongside drainage improvements at 1.35 million points and upgrades to over 100,000 roadside technology assets to support connected and autonomous vehicles (projected at 36% market share by 2035).[2] Investments include £950 million for 2,500 rapid electric vehicle charging points by 2030 and small-scale schemes (£2-25 million each) across 17 routes totaling 147 miles to alleviate congestion and bolster freight logistics.[2] Innovation priorities incorporate AI and data analytics for real-time information, worker safety, and journey reliability, addressing challenges like the 72% of structures over 45 years old by 2025 and rising severe weather impacts.[149][2] The draft RIS3, published in August 2025, awaits finalization by March 2026 following National Highways' Strategic Business Plan submission in September 2025 and Office of Rail and Road review.[149]| Objective Category | Key Targets and Metrics |
|---|---|
| Safety | Zero harm by 2050; 50% KSI reduction; upgrade 50% of low-rated roads to 3-star.[149][2] |
| Environment & Sustainability | Net zero operations (2030), construction emissions (2040); 10% biodiversity gain; 3M trees by 2030.[2] |
| Infrastructure Renewal | 4,660 miles asphalt resurfacing; 170 major structures renewed.[2] |
| Technology & Efficiency | 2,500 EV chargers by 2030; AI/data for real-time info; CAV support.[2][149] |
Technological and Innovation Initiatives
National Highways has pursued the Digital Roads initiative to integrate data, advanced technology, and connectivity across the Strategic Road Network (SRN), aiming to enhance design, construction, operation, and utilization of highways. This program outlines ambitions for 2025, including real-time data sharing for traffic management and predictive maintenance using sensors and analytics, with a long-term vision of fully connected infrastructure by 2030.[150] The initiative supports the Digital Data and Technology Strategy for 2023-2025, which emphasizes cloud-based platforms, interoperability of systems, and investments exceeding £1 billion in digital capabilities to enable agile decision-making and improved user experiences.[151][152] A core component involves smart motorway technologies, which deploy variable speed limits, dynamic hard shoulder use, and automated incident detection systems like MIDAS (Motorway Incident Detection and Automatic Signalling). In response to operational challenges, National Highways completed nationwide upgrades to stopped vehicle detection by March 2025, installing bidirectional radar units on all-lane running sections to identify breakdowns and activate emergency areas or traffic management more rapidly.[153][90] These enhancements, part of a £500 million safety stocktake program initiated in 2022, addressed prior technology outages—such as four-week failures on stretches like the M62 in 2024—that had raised concerns over reliability.[154] Despite claims of threefold higher breakdown risks on smart motorways versus conventional ones in a 2023 internal report, post-upgrade data from 2025 indicates reduced serious injuries overall on equipped sections.[91][9] In artificial intelligence and data analytics, National Highways advanced trials in December 2023 selecting three suppliers to deploy AI for minimizing roadworks disruptions, including predictive modeling of traffic flows and automated signage adjustments, resulting in 2,100 fewer delayed journeys during a two-month M6 test.[155][156] Machine learning applications focus on outcome prediction via statistical models integrated with Azure and Databricks platforms for asset management and interoperability.[157][158] The Moonshot project, launched in 2023, tests non-destructive evaluation technologies like drone-based inspections and AI-driven structural health monitoring to transform maintenance practices, drawing on international validations for efficiency gains.[159] The broader Innovation and Research Strategy for Road Period 2 (2025-2030) prioritizes generational shifts through partnerships, such as with the Connected Places Catapult, targeting decarbonization, safety enhancements, and customer-centric tech like real-time journey planning.[160][161] These efforts align with RIS3 objectives but face scrutiny over implementation timelines and tech reliability, with official reports emphasizing empirical pilots over unproven deployments.[162]Long-Term Network Resilience
National Highways' long-term network resilience efforts center on adapting the Strategic Road Network (SRN) to persistent threats including climate change-induced extreme weather, infrastructure degradation, and escalating traffic demands, with a strategic horizon extending to 2050 as outlined in the 2023 "Connecting the Country" plan. This framework prioritizes physical asset hardening against flooding, heat expansion, and storm damage, informed by risk assessments projecting increased precipitation intensity and temperature extremes under UK Climate Projections (UKCP18). Empirical data from historical events, such as the 2014 floods disrupting multiple motorways, underscore causal vulnerabilities in drainage systems and embankment stability, necessitating proactive retrofitting over reactive repairs.[163][164] Key adaptation measures include enhanced flood resilience at over 100 SRN locations through upgraded culverts, embankments, and pumping stations, achieving 95 targeted interventions by the fourth round of Adaptation Reporting Power submissions in 2023. Temperature resilience initiatives address asphalt rutting and buckling from projected summer highs exceeding 40°C, incorporating heat-resistant surfacing materials tested under accelerated weathering simulations. Business continuity planning integrates real-time condition monitoring via sensors and AI-driven predictive analytics to preempt failures, reducing outage durations from weather events by an estimated 20-30% in modeled scenarios. These efforts align with the Environmental Sustainability Strategy's nine priorities, emphasizing empirical validation through post-event audits rather than unverified projections.[163][165][97] Integration with broader resilience frameworks involves collaboration with Local Resilience Forums for localized threat mapping and alignment with the Department for Transport's climate adaptation goals, though independent analyses highlight gaps in funding allocation for non-flood risks like subsidence from drier soils. The Road Investment Strategy 3 (RIS3, 2025-2030) allocates resources for optimized physical network enhancements, including biodiversity corridors to bolster ecological buffers against erosion, with quantifiable targets for minimizing climate-related disruptions to under 1% of annual network availability. Ongoing monitoring via the Net Zero Knowledge Zone tracks adaptation efficacy across 17 topics, ensuring causal linkages between interventions and reduced vulnerability metrics.[163][166][164]Economic and Societal Impact
Contributions to Economic Growth and Mobility
The Strategic Road Network (SRN), comprising England's motorways and major A-roads managed by National Highways, underpins economic growth by enabling efficient freight and passenger mobility. It handles one-third of all road traffic and 70% of road freight, which accounts for 81% of domestic freight tonnage and 75% of imports and exports by value.[116][167] This connectivity supports just-in-time supply chains critical for manufacturing, retail, and logistics sectors, reducing transport costs and enhancing competitiveness.[116] SRN-reliant industries generate £410 billion in gross value added (GVA) and sustain 7.6 million jobs, with projections estimating £578 billion GVA and 8 million jobs by 2050, driven by sustained reliance on reliable road access for productivity and market expansion.[116] Investments under the first Road Investment Strategy (2015-2020), totaling £15.2 billion across over 100 schemes, yielded £22.6 billion in user benefits, including time savings and reliability gains, with 56% directed to business and freight users.[115] Improvements to the SRN foster wider economic effects through agglomeration and accessibility enhancements; econometric analyses show a 10% increase in road capital stock correlates with 0.9% higher output, while a 10% rise in accessibility boosts productivity by 0.4-0.7% and employment by 0.5-3.5%.[115] These gains connect regional economies to international gateways like ports and airports, facilitating trade and inward investment.[116] In terms of mobility, the SRN carried 96.9 billion vehicle miles in 2024, up 1.1% from the prior year, supporting commuter access to employment and enabling housing developments linked to 100,638 new homes and 42,440 jobs in 2022/23.[168][116] By linking major urban centers, it reduces inter-regional travel times, promoting labor mobility and tourism, though benefits are concentrated in high-density corridors.[115]Broader Effects on Society and Environment
The strategic road network (SRN) managed by National Highways bolsters societal connectivity by providing essential links between urban centers, ports, airports, and rural areas, enabling efficient long-distance travel for individuals and freight that underpins economic productivity and access to opportunities.[169] This infrastructure supports reliable mobility, reducing isolation in remote regions and facilitating trade that contributes to national prosperity.[169] However, heavy reliance on the SRN fosters car dependency, exacerbating congestion that imposes substantial time losses and economic burdens on users, while traffic noise and physical barriers create community severance, hindering pedestrian access to amenities and social interactions.[170][171] Empirical studies indicate that residing near urban motorways correlates with diminished wellbeing, including heightened stress and reduced life satisfaction, attributable to chronic exposure to noise and visual intrusion.[172] Road accidents on the network further compound social costs, with collisions disproportionately affecting vulnerable populations in deprived areas through elevated injury risks.[173] Environmentally, the SRN's maintenance and construction activities emitted approximately 734,000 tonnes of CO2 equivalent in 2020, with asphalt usage alone accounting for 77,300 tonnes of CO2 equivalent that year, contributing to broader transport-related greenhouse gas outputs that form the largest share of UK domestic emissions from cars and vans.[174][175][169] National Highways has pursued decarbonization via its net zero plan, targeting zero operational emissions by 2030 and zero from construction and maintenance by 2040, achieving a 50% reduction in corporate emissions relative to 2017-18 levels through measures like low-carbon materials and electrification.[176][165] On biodiversity, the agency claims to have attained no net loss across its activities by 2025, via habitat enhancements and reconnection on 4,500 hectares of land under its control, including pollinator-friendly planting and wildlife crossings to mitigate fragmentation.[177][178] Independent monitoring by the Office of Rail and Road verifies progress against regulatory requirements, though post-project evaluations reveal shortfalls in delivering specific mitigations, such as tree replanting survival rates.[179][180] Road expansion continues to pose risks of habitat loss and pollution runoff, affecting local ecosystems despite adaptive strategies like sustainable drainage systems.[181][182]Comparative Analysis with Alternatives
Road investments managed by National Highways typically demonstrate higher benefit-cost ratios (BCRs) than comparable rail projects in the UK, with analyses showing road improvements yielding substantially greater economic returns due to broader accessibility and lower construction costs. For instance, a study of UK transport schemes found that road enhancements provided higher internal rates of return compared to railway investments, attributing this to roads' ability to serve diverse freight and passenger demands without the need for specialized infrastructure like electrification or signaling upgrades.[183] Rail tracks are estimated to cost 6 to 7 times more to build per unit length than equivalent road capacity, limiting scalability for general traffic volumes.[184] This disparity arises because motorways facilitate higher throughput—passenger and freight flows per lane or track are approximately three times greater on the UK's motorway and trunk road network than on rail lines—enabling more efficient integration with just-in-time logistics and personal vehicle use.[184] In terms of mobility and economic growth, National Highways' network supports greater flexibility and decentralization than fixed-rail alternatives, reducing travel times for door-to-door journeys and agglomeration benefits for businesses. Empirical evidence from UK local economic evaluations indicates that road projects enhance market access and productivity more effectively for suburban and rural connectivity, where rail stations are sparse, contributing to GDP through lower generalized transport costs for commuters and goods.[185] High-speed rail (HSR), such as the canceled HS2 extensions, often underperforms in BCRs for intercity links due to high upfront capital outlays—exceeding £100 billion for full implementation—and dependency on high-density corridors, whereas motorways deliver incremental capacity expansions at lower marginal costs, with National Highways' Road Investment Strategy (RIS) projecting over £2 in benefits per £1 invested across £15.2 billion in capital spending.[186] However, rail alternatives excel in emissions efficiency for freight, emitting 76% less CO2 per tonne-kilometer than road haulage, though this advantage is offset by rail's lower modal share (around 8-10% of UK freight) and underutilization outside peak urban routes.[187] Environmental and societal trade-offs further highlight roads' pragmatic edge for UK's dispersed population, as alternatives like bus rapid transit or expanded local rail struggle with last-mile connectivity and variable demand, leading to underused capacity. Cost-benefit analyses reveal inconsistencies in rail appraisals, where UK decisions for freight rail often apply looser criteria than roads, potentially inflating perceived viability despite evidence that road networks better align with actual usage patterns—motorways carry over 30 billion vehicle miles annually versus rail's constrained passenger focus.[188] International benchmarks, such as OECD comparisons, underscore that while rail suits high-volume linear corridors, UK's multimodal reliance favors roads for resilience against disruptions, with motorways enabling adaptive routing absent in rail's fixed infrastructure.[189] Prioritizing rail over road maintenance has correlated with regional disparities, as seen in lower per-capita rail investment yielding minimal growth spillovers compared to motorway upgrades.[190]| Aspect | Road (National Highways) | Rail Alternatives |
|---|---|---|
| Construction Cost per Capacity Unit | Lower (e.g., £10-20m/km for widening) | Higher (6-7x for track, £50-100m/km for HSR)[184] |
| BCR Range (UK Schemes) | 1.5-4.0+ for improvements[186] | 1.0-2.5, often lower for new lines[183] |
| Throughput Efficiency | 3x higher flows per lane/track[184] | Better per passenger-km but route-limited |
| Emissions (Freight) | Higher CO2 per tonne-km | 76% lower[187] |
| Flexibility | High (personal/door-to-door) | Low (station-dependent) |
