Interstate 980 (I-980) is a short 2.03-mile (3.27 km) auxiliary Interstate Highway entirely within Oakland in Northern California, connecting I-580 and State Route 24 (SR 24) to I-880 near Downtown Oakland. I-980 passes the Oakland Convention Center and near the famous Jack London Square. I-980 is commonly considered the dividing line between Downtown Oakland and West Oakland. The freeway was planned as the eastern approach to the Southern Crossing. The segment between I-880 and 17th Street is officially known as the John B. Williams Freeway, after the former director of the city of Oakland's Office of Community Development.[2] In addition, I-980 and SR 24 in Oakland are both designated as part of the Grove-Shafter Freeway, after streets the route travels along (Grove Street was later renamed Martin Luther King Jr. Way).[3]

I-980 was used as an alternate route between Oakland and San Francisco when the Cypress Viaduct carrying I-880 collapsed in the 1989 Loma Prieta earthquake. Traffic headed from the south would have to use I-980 to I-580 west to I-80 west to get across the San Francisco–Oakland Bay Bridge to reach San Francisco. This ended when I-880 reopened on a new alignment in 1997 (1998 to and from I-80 east).

Route description

[edit]

The entirety of I-980 is defined in section 624 of the California Streets and Highways Code as Route 980, and that the highway is from "Route 880 to Route 580 in Oakland".[4] This definition roughly corresponds with the Federal Highway Administration (FHWA)'s route logs of I-980.[5][1]

Although I-980 physically goes north and south, it is signed as an east–west route like SR 24. Immediately after traffic leaves I-880 on elevated connector ramps, I-980 then descends below grade to pass under downtown city streets. The freeway then ascends above grade to pass over SR 123 (San Pablo Avenue) and 27th Street before reaching I-580 and SR 24.[citation needed]

The freeway itself lacks overhead guide signs mentioning I-980. Immediately after exit 1B (SR 123/17th Street) going eastbound on I-980 is a guide sign mentioning the junction with I-580. Likewise, the guide signs on westbound I-980 at exit 1D (18th Street) list I-880 and San Jose as a control city. Since 2018, Jackson Street and I-880 south have been signed as exits 1B and 1A in the westbound direction.[citation needed]

I-980 is part of the California Freeway and Expressway System[6] and is part of the National Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration (FHWA).[7]

History

[edit]

The route known as I-980 was originally added to the state highway system in 1947 as part of Legislative Route 226 (LRN 226)[8] and to the California Freeway and Expressway System in 1959.[9] This segment of LRN 226 became part of SR 24 in the 1964 state highway renumbering.[10]

Construction on a Highway 24 freeway connecting Downtown Oakland with the Caldecott Tunnel in the Oakland Hills began in the 1960s. It was also originally intended to serve the Southern Crossing and a regional shopping mall in Oakland, neither of which were ever built. While the freeway was completed from the tunnel to I-580 and 27th Street, construction of the segment extending it further west to the Nimitz Freeway (present-day I-880) resulted in community opposition due to about 503 homes in the freeway's path (and thus slated to be demolished or moved). In 1972, a federal lawsuit halted its construction until Caltrans agreed to build replacement housing. With city officials still pushing for the freeway's completion, a compromise was also reached to change the design from an elevated freeway to a depressed freeway, decreasing noise.[11]

To help complete the freeway with federal funding, the FHWA approved the addition of the segment to the Interstate Highway System in January 1976, with the Interstate money only used west of SR 123 (San Pablo Avenue).[12]; thus, I-980 is designated as part "chargeable" Interstate and part "non-chargable", 23 U.S.C. § 103(c)(4)(A) Interstate.[1] The segment's number was legislatively changed from Route 24 to I-980 in 1981,[13] and it finally opened in 1985.[11]

Future

[edit]

The San Francisco Chronicle reported in November 2015 about a grassroots organization of local architects and planners, supported by Oakland mayor Libby Schaaf, that propose to replace I-980 with a landscaped city boulevard.[14] ConnectOakland is coordinating the push for a replacement. In January 2017, I-980 was included in Congress for the New Urbanism "Freeways without Futures" report.[15][16]

Caltrans and the city of Oakland received a $680,000 Reconnecting Communities planning grant, funded by the 2021 Infrastructure Investment and Jobs Act, to study rebuilding or removing I-980.[17] BART may use the corridor as an approach for a second Transbay Tube.[11]

Arguments for replacement focus on the freeway's low volume of traffic and negative impact on surrounding neighborhoods. Concerns are however raised on whether the existing surface streets can handle the relocated traffic, and whether it may actually increase gentrification in the area.[15][11]

from Grokipedia
Interstate 980 (I-980) is a 2.03-mile auxiliary Interstate Highway spur confined entirely to , functioning as an east-west urban connector between Interstate (Nimitz Freeway) near Jack London Square and the interchange of Interstate 580 and State Route 24 (Grove-Shafter Freeway). It facilitates commuter traffic from toward eastern Bay Area destinations including Walnut Creek and Concord, as well as access to Oakland International Airport via linkages to I-880. Designated the John B. Williams Freeway from its western terminus to 17th Street, I-980 was completed on March 6, 1985, following construction that began in 1962 and overcame legal challenges including a 1972 lawsuit that influenced its final depressed alignment through West Oakland. The route's development traces to 1947 state highway planning as part of Legislative Route 226, with federal Interstate approval in 1976 and full designation in 1983. A Bay Area Rapid Transit (BART) line runs parallel between its eastbound and westbound lanes, integrating rail and highway infrastructure. I-980's construction displaced 503 homes, 22 businesses, 4 churches, and 155 trees, severing West Oakland neighborhoods from downtown and contributing to socioeconomic disinvestment in affected areas predominantly home to residents. Post-1989 Loma Prieta earthquake, when the Cypress Viaduct portion of I-880 collapsed, I-980 provided essential detour capacity amid widespread disruptions. Operating at approximately 42% of designed capacity based on average daily traffic volumes, the freeway is now subject to Caltrans' Vision 980 Study, initiated to evaluate transformative options such as partial removal to restore community connectivity, add housing and open spaces, or enhance , with community input guiding Phase 1 completion targeted for late 2025.

Route Description

Alignment and Features

Interstate 980 is a 2.03-mile auxiliary Interstate Highway located entirely within the city of Oakland, Alameda County, California. It commences at a directional interchange with Interstate 880 (Nimitz Freeway) near the Embarcadero in West Oakland, adjacent to Jack London Square. The route extends eastward through downtown Oakland on a flat urban alignment, transitioning between depressed and elevated sections, before terminating at a four-level stack interchange with Interstate 580 (MacArthur Freeway) and State Route 24 (Grove-Shafter Freeway), commonly referred to as the MacArthur Maze. The freeway features 5 to 10 general purpose lanes across its segments, supplemented by auxiliary lanes, with a right-of-way width of approximately 100 feet and medians ranging from 38 to 99 feet. Elevated portions include viaducts spanning avenues such as and San Pablo, while a section near Martin Luther King Jr. Way incorporates the () rail line within the median. Shoulders on elevated structures measure eight feet wide, narrower than standard Interstate Highway specifications. Portions of the alignment are classified as landscaped freeways, with completion of construction occurring in 1985 after phases beginning in the . The route bisects densely developed neighborhoods, functioning primarily as a connector linking the Nimitz Freeway with the MacArthur Freeway system.

Exit List

Interstate 980 features eight exits over its 2.03-mile length, numbered sequentially by postmile from its western terminus at Interstate 880 in Oakland to its eastern terminus at the junction with Interstate 580 and State Route 24; the numbering follows Caltrans' uniform system for east-west routes.

Design and Engineering

Construction Standards

Interstate 980 was designed and built to comply with federal standards, including full control of access, grade-separated interchanges, and minimum geometric criteria for safety and capacity in an urban setting. The granted approval for construction deviations specific to site constraints, ensuring the route functioned as an auxiliary interstate connector. These standards encompassed construction for elevated viaducts, which dominate the 2-mile alignment to navigate dense residential and commercial districts in Oakland. A notable exception to standard interstate geometrics was the use of 8-foot-wide shoulders on elevated structures, narrower than the typical 10-foot requirement, as approved by the FHWA on January 29, 1976, to fit within right-of-way limitations. widths adhered to the 12-foot minimum per for through , supporting the divided freeway's capacity as a principal arterial. The configuration varies from five to ten lanes total across segments, with three lanes typical in each direction plus auxiliary lanes near interchanges. Post-1972 construction phases incorporated environmental mitigations, such as earthen berms along certain sections to reduce noise and emissions propagation into adjacent neighborhoods, reflecting evolving state practices under the Streets and Highways Code. Seismic reinforcement aligned with California Department of Transportation guidelines for earthquake-prone regions, including ductile detailing in bridges and piers completed by 1985. Vertical clearances under overcrossings met the federal minimum of 14 feet, with some structures providing up to 16.8 meters of curb-to-curb roadway width on key spans.

Structural Characteristics

Interstate 980 is an approximately 2-mile-long auxiliary urban freeway constructed as an elevated traversing central . The route features a divided configuration with structures, including multiple overpasses and bridges spanning local streets such as 30th Street, San Pablo Avenue, and Martin Luther King Jr. Way. The mainline typically provides three lanes in each direction, though the configuration expands to five to ten lanes in sections incorporating auxiliary ramps and interchanges. Structures utilize continuous box beam designs capable of supporting HS-20 loading, with approach roadway widths varying from 12.8 to 16.8 meters depending on the span. Elevated portions include 8-foot shoulders, narrower than full , reflecting urban constraints during construction. No tunnels are present along the route, which relies entirely on and bridge engineering to navigate dense city without grade-level interruptions. Bridge medians are generally closed with non-mountable barriers, and skew angles approach 99 degrees at certain crossings to align with underlying roadways.

History

Planning and Approval

The planning of what would become Interstate 980 originated in the 1940s as the Grove-Shafter Freeway, proposed in 1946 to connect Oakland's downtown area to broader Bay Area infrastructure, including as the eastern approach to the unbuilt Southern Crossing—a second transbay bridge linking Oakland to San Francisco. In 1959, the California State Legislature incorporated the route into the state highway system as Legislative Route 226, aligning it from the MacArthur Freeway (now I-580) westward toward a planned junction with Interstate 880 and beyond, as part of the expanding freeway network under the Federal-Aid Highway Act of 1956. The project encountered significant local opposition in West Oakland during the , driven by concerns over community displacement and the demolition of hundreds of homes and businesses in predominantly low-income and minority neighborhoods, reflecting broader freeway revolt movements nationwide. A key legal challenge came in 1972 when attorney Stephen Berzon filed a on behalf of affected residents, temporarily halting construction and compelling design modifications, including a sunken (depressed) alignment to reduce visual and noise impacts, along with commitments to housing relocation assistance. Federal approval proceeded despite these hurdles, with the segment designated as a non-chargeable Interstate route under Section 139(a) of the Interstate Highway Act in July 1976, exempting it from California's mileage allocation limits and enabling funding without additional state quota deductions. This designation solidified its role as an auxiliary spur connecting I-880 to the East Bay's primary arterials, prioritizing regional traffic relief and port access over unresolved local objections.

Construction Phases

Construction of Interstate 980 commenced in the early , with initial work on elevated segments beginning around 1962 as part of broader efforts to link Oakland's growing freeway network. By 1968, focused building advanced to connect the recently completed Grove-Shafter Freeway (now I-580) eastward to the Eastshore Freeway (I-880), targeting a roughly 2-mile corridor through West Oakland. Early phases emphasized elevated structures for the first approximately , aligning with standard Interstate design practices to minimize surface disruption initially. Progress halted in 1972 following a challenging the project's environmental and social impacts, including displacement in predominantly Black neighborhoods. Construction resumed later in the decade after revisions incorporated resident input, shifting subsequent segments to a depressed (below-grade) configuration to reduce visual barriers and noise, while retaining elevated approaches at the western end near I-880 and eastern terminus with State Route 24. This hybrid design reflected compromises amid opposition, extending the timeline significantly beyond initial projections. The freeway achieved full completion and opened to traffic in , over two decades after planning inception and nearly 20 years after groundbreaking. Final contracts addressed interchanges, such as the 17th Street segment named for John B. Williams, ensuring connectivity for approximately 40,000 daily vehicles by linking to regional routes. Delays stemmed from legal challenges and design alterations rather than technical hurdles, marking I-980 as one of the last urban Interstates built in during a period of waning freeway expansion.

Completion and Initial Operations

The final segment of Interstate 980, connecting the partially completed sections through downtown Oakland, was opened to traffic on March 6, 1985, following a ribbon-cutting ceremony that marked the highway's full operational readiness. This completion ended over two decades of intermittent construction that had begun in the 1960s, integrating the approximately 2-mile route as a critical east-west link between Interstate 880 (the Nimitz Freeway) in West Oakland and Interstate 580 toward Hayward. The highway's design facilitated direct access for eastbound traffic from I-880 to I-580, alleviating some congestion on local arterials like Grove Street and 7th Street, though initial operations were constrained by the need for adjacent infrastructure adjustments, including ramp connections and signage installations. Upon opening, I-980 operated under standard California Department of Transportation (Caltrans) maintenance protocols, with three lanes in each direction featuring concrete barriers and overhead signage for interchanges at key points such as Martin Luther King Jr. Way and the transition to I-580. Early traffic patterns reflected its role as a bypass for through-traffic avoiding Oakland's , with average daily volumes estimated in the tens of thousands based on regional freeway data from the mid-1980s, though specific inaugural counts were not publicly detailed in contemporary reports. No major operational disruptions were noted in the immediate post-opening period, allowing seamless incorporation into the Interstate system despite prior community concerns over displacement during construction.

Role in 1989 Loma Prieta Earthquake

The Loma Prieta earthquake, a 6.9 Mw event centered approximately 10 miles northeast of Santa Cruz on October 17, 1989, at 5:04 p.m. PDT, caused widespread disruption to Bay Area infrastructure, including elevated freeways in Oakland. Interstate 980, an urban elevated route, sustained localized structural damage, particularly to outrigger joints and a bent in the curved connector structure linking it to Interstate 880 near the Cypress Viaduct. This damage included stress to knee joints extending from the structure but did not result in collapse or fatalities, contrasting sharply with the Cypress Viaduct's failure on I-880, which killed 42 people. Despite the damage, I-980 remained operational after inspections and became a critical detour for traffic rerouted from the collapsed I-880 structure, facilitating connections between the Nimitz Freeway (I-880) remnants and the MacArthur Freeway (I-580). This shift handled through traffic previously using I-880, though it led to significant congestion in Oakland as drivers sought alternatives amid the partial closure of the . The freeway's role underscored vulnerabilities in pre-1990s seismic design for elevated urban interstates, prompting post-event analyses of joint performance that informed retrofit standards. By late 1989, repairs allowed I-980 to support recovery efforts, including the eventual reconstruction linking it to a redesigned I-880 by 1997.

Impacts

Community Displacement

The construction of Interstate 980, which began in 1968 and opened to traffic in , directly displaced residents and businesses in West Oakland by demolishing 503 houses and removing 22 businesses, resulting in the loss of 142 jobs. This affected approximately 500 primarily families in a neighborhood already designated as blighted, facilitating acquisition of 42 acres of land, including 155 trees and 4 churches. The freeway's 1.6-mile elevated and depressed corridor carved a physical barrier through the eastern edge of West Oakland, severing connections between the community and downtown Oakland's economic opportunities. Prior to construction, West Oakland's low-income, predominantly African American population had been isolated by earlier freeways like I-880 and I-580, but I-980 exacerbated fragmentation by prioritizing automotive infrastructure over neighborhood cohesion, often justified by policies targeting "blight" in minority areas. Long-term consequences included persistent disinvestment, with decreased property values, elevated air and concentrated in remaining Black neighborhoods, and unfulfilled promises of replacement or economic revitalization. The structure's design limited pedestrian and bicycle access, heightening safety risks and reinforcing socioeconomic divides, as evidenced by demographic shifts and underutilized land along the corridor decades later.

Transportation and Economic Benefits

Interstate 980 provides a , elevated limited-access connection between Interstate in West Oakland and Interstate 580 east of , spanning approximately 2 miles and enabling through-traffic to circumvent congested surface streets in central Oakland. This linkage supports regional mobility for commuters traveling from the toward the and Central Valley, as well as limited freight movements integrating with the broader Interstate network. With an volume of around 73,000 vehicles as of the mid-2010s, the freeway operates below its theoretical capacity of over 18,000 vehicles per peak hour, suggesting it alleviates some pressure on parallel arterials without inducing severe bottlenecks. In terms of redundancy, I-980 demonstrated value during the , when the collapse of the nearby Cypress Viaduct on I-880 shifted traffic flows onto it, preserving essential east-west connectivity across the and to . Economically, the route contributes to interstate commerce by facilitating vehicle movements that indirectly bolster access to Oakland's port and industrial zones via I-880 integration, though trucks occasionally utilize segments for port-bound routing north of I-880. However, studies indicate that anticipated broader economic revitalization in adjacent areas has not fully materialized, with the freeway's underutilization highlighting limited catalytic effects on local development compared to initial planning expectations.

Long-Term Urban Effects

The construction of Interstate 980 through West Oakland displaced approximately 500 Black families between the 1960s and 1980s, fragmenting established neighborhoods and eroding social cohesion in the area. This physical severance created a persistent barrier between West Oakland and , restricting pedestrian access, local commerce, and community interactions, which in turn fostered long-term in and businesses adjacent to the corridor. Neighborhoods along the route have since experienced stalled urban revitalization compared to adjacent Uptown areas, with the freeway's elevated and depressed sections forming a 2-mile trench that impedes connectivity and land use integration. Environmental burdens from I-980 have compounded these urban divides, with elevated levels of air and contributing to disproportionate outcomes in West Oakland. Adjacent communities report asthma hospitalization rates in the 99th to 100th statewide, linked in part to emissions and barrier-induced stagnation of local airflows. Long-term exposure to these pollutants has been associated with higher incidences of respiratory and cardiovascular issues among lower-income and minority residents, exacerbating inequities tied to the freeway's placement through historically underserved areas. from the 1.6-mile segment continues to degrade , correlating with sleep disruption and reduced property values in proximity, though broader regional air quality improvements from vehicle efficiency gains have not fully mitigated localized effects. Economically, I-980 facilitated regional freight and commuter flows, supporting Oakland's port-adjacent logistics but yielding uneven urban outcomes. While enabling faster links between Interstate 880 and 580, the infrastructure's legacy includes underutilized land parcels and inhibited mixed-use development in West Oakland, perpetuating cycles of poverty and limited job access for nearby residents. Studies attribute this to the "barrier effect," which has constrained economic spillover from downtown growth, leaving West Oakland with higher vacancy rates and slower recovery from mid-20th-century industrial decline compared to freeway-avoided zones. Over decades, these dynamics have reinforced spatial mismatches in employment opportunities, with data showing persistent income disparities across the divided urban fabric.

Controversies and Debates

Criticisms of Social Disruption

The construction of Interstate 980, spanning from 1968 to its completion in 1985, displaced 503 houses, four churches, and 22 businesses in West Oakland, resulting in the loss of 142 jobs and affecting primarily African American residents. This process, initiated amid efforts targeting areas deemed blighted, fragmented established neighborhoods and uprooted families from multigenerational homes, with over 500 mostly Black-owned properties demolished. The elevated freeway structure physically bisected West Oakland over 42 acres, creating a barrier that severed pedestrian and social connections between the neighborhood and Oakland's economic hubs. Critics highlight how this division isolated residents from employment opportunities, schools, and civic amenities, exacerbating social fragmentation and reducing community cohesion in an area already shaped by and segregation. Construction also removed 155 mature trees, diminishing green spaces and contributing to immediate environmental stressors like noise and dust that disrupted daily life. Long-term criticisms center on persistent , with the highway's placement—linked to discriminatory practices—leading to depressed values estimated in the hundreds of millions and heightened exposure to traffic-related , correlating with elevated rates among residents. The infrastructure's role in perpetuating economic disconnection is evidenced by West Oakland's slower recovery compared to adjacent areas, as the "trench-like" corridor hindered revitalization and reinforced patterns of inequality.

Defenses Based on Infrastructure Necessity

Proponents of Interstate 980's construction argued that it was essential for establishing a direct, high-capacity link between Interstate 880 (Nimitz Freeway) near the and Interstate 580 (via State Route 24, MacArthur Freeway), thereby integrating Oakland into the broader and facilitating efficient regional travel. This connectivity was deemed critical in the post-World War II era of rapid and automobile dependency, as surface streets in were ill-equipped to handle projected increases in commuter and commercial traffic, potentially exacerbating congestion and delaying goods movement to and from the port. Planners, including the California Division of Highways (predecessor to Caltrans), emphasized that without such a freeway , Oakland risked isolation from east-west corridors, hindering with surrounding counties. The infrastructure was also justified as a foundational element for Oakland's City Center plans in the and , where the freeway alignment was aligned with ambitions to modernize the urban core through commercial and civic projects, such as office towers and transit hubs, by providing reliable access for workers and visitors. Originally conceived as the eastern approach to a proposed second San Francisco-Oakland Bay Bridge (Southern Crossing), I-980's design accommodated anticipated transbay traffic volumes that would otherwise overload existing routes like I-80, underscoring its role in preempting future bottlenecks based on traffic forecasts from the era. Federal Interstate funding, allocated under the 1956 Highway Act, further reinforced this necessity, as the project fulfilled mandates for a cohesive national network prioritizing speed and capacity over local street grids. Despite subsequent criticisms of underutilization— with average daily traffic around 50,000 vehicles pre-pandemic, lower than adjacent segments—defenders maintained that the freeway's existence prevented worse gridlock on parallel arterials like 7th Street and Broadway, preserving throughput for trucks serving the port, which handles over 2.5 million containers annually. Empirical assessments from Caltrans transportation concept reports highlight I-980's function as a designated truck route under Alameda County's Good Movement Plan, ensuring resilience in freight logistics amid growing Bay Area population and e-commerce demands. This causal link between infrastructure capacity and economic vitality was cited by state engineers as evidence that removal without equivalents could redirect congestion to residential areas, undermining the original intent of systemic relief.

Future Developments

Vision 980 Study

The Vision 980 Study, initiated by the California Department of Transportation (Caltrans) District 4 in 2024, examines potential transformations of the Interstate 980 corridor in Oakland, spanning approximately 2 miles from its junction with I-880 in downtown Oakland to I-580 in North Oakland. As part of Caltrans' Reconnecting Communities program, the study addresses the freeway's historical role in dividing West Oakland from downtown, creating barriers to pedestrian and vehicular movement, economic access, and community cohesion since its construction in the 1980s displaced predominantly Black and low-income neighborhoods. The initiative prioritizes a community-led visioning process to identify equitable transportation and land-use concepts that mitigate these disruptions while accommodating regional traffic demands. Phase 1 of the study, spanning spring 2024 to fall 2025, focuses on assessing current impacts through public engagement, including surveys on crossing patterns over I-980 and perceptions of its effects on daily life and economic opportunities. Caltrans conducted initial outreach activities, such as virtual and in-person events, gathering input from over 1,000 participants on how the corridor influences travel between West Oakland and ; results indicated frequent crossings for work, shopping, and social purposes, underscoring the need for improved connectivity. By June 2025, the study advanced to evaluating three corridor scenarios: maintaining the existing elevated freeway with enhancements, partially reconstructing or lowering sections to reduce barriers, and full removal or replacement with surface streets and alternative transit options like rail or boulevards. Public feedback from the second round of engagement, concluded in July 2025, informed refinements to these scenarios, with events including a October 2025 along the corridor to visualize changes and collect direct resident input. Oversight involves collaboration with the City of Oakland's Planning Commission and groups like the Bicycle and Pedestrian Advisory Commission (BPAC), ensuring alignment with local plans such as the West Oakland Specific Plan. Phase 2, anticipated post-2025, will develop detailed feasibility analyses, environmental reviews, and cost estimates, though funding constraints and engineering challenges—such as integrating with I-880 and I-580 interchanges—remain key hurdles. The study emphasizes data-driven outcomes over ideological priorities, drawing on of freeway-induced displacements from the 1960s-1980s era to guide restorative measures without presupposing removal.

Proposed Alternatives and Challenges

The Vision 980 Study, initiated by the California Department of Transportation (Caltrans) in collaboration with the City of Oakland, outlines three primary corridor scenarios for reimagining Interstate 980 (I-980) to address its role in dividing West Oakland from . The "Enhance" scenario proposes retaining the existing freeway while adding improvements such as better pedestrian and bicycle pathways, enhanced interchanges, and noise barriers to mitigate barriers without major structural changes. The "Cover" scenario involves constructing lids or caps over depressed sections of the highway, potentially creating up to 25 acres of new developable land for housing, parks, or commercial uses, similar to freeway capping projects in other cities like Seattle's replacement. The "Remove" scenario contemplates partial or full demolition of the elevated and at-grade segments, replacing them with surface streets, boulevards, or transit-oriented infrastructure to fully reconnect neighborhoods, drawing from successful removals like San Francisco's Embarcadero Freeway. These alternatives face significant engineering and logistical hurdles, as I-980's 2-mile urban alignment includes elevated viaducts over rail lines and neighborhoods, requiring complex seismic retrofitting or dismantling amid active Bay Area rail corridors operated by Union Pacific and . Demolition or capping would necessitate temporary traffic rerouting onto already congested I-880 and I-580, potentially exacerbating commute times for the highway's daily 100,000+ vehicles, many serving as a critical east-west link between I-880 and Interstate 24. Replacement infrastructure, such as new ramps at the interchange, could demand coordination with the and expansions already underway nearby. Financial challenges are acute, with estimates for full removal exceeding $1 billion based on comparable projects like Boston's or Rochester's Inner Loop North removal, amid California's constrained transportation budget facing competing priorities such as and seismic upgrades elsewhere. Funding would rely on federal grants under programs like the Reconnecting Communities and Neighborhoods Program, but approval hinges on environmental impact statements under the , which could reveal unforeseen contamination from the freeway's 1960s-1980s era. Politically, alternatives must navigate divided community input: surveys from Phase 1 of Vision 980, closing in October , showed varied support, with removal favored by some for equity reasons but opposed by others concerned about economic disruption to port-related trucking. Caltrans plans Phase 2 detailed feasibility analysis post-, but achieving consensus remains uncertain given historical distrust from the freeway's original displacement of approximately 500 Black families in West Oakland.
