Pamban Bridge
Pamban Bridge
from Wikipedia

Pamban Bridge (Tamil: [paːmbɐn], romanised: pāmban) was a railway bridge that connected the town of Rameswaram on Pamban Island with Mandapam in mainland India. Opened on 24 February 1914, it was India's first sea bridge, and was the longest sea bridge in India until the opening of the Bandra–Worli Sea Link in 2010. It was a conventional bridge resting on concrete piers with a double-leaf bascule section midway, which could be raised to let ships and barges pass through.

Key Information

The Pamban bridge was the only surface transport link that connected Rameswaram to the mainland India until 1988, when a road bridge was constructed parallel to the railway bridge. In 2020, construction of a new bridge closer to the existing one began which was planned to eventually replace the existing bridge. In December 2022, rail transportation on the bridge was suspended permanently as the bascule section had weakened significantly due to corrosion.

History

[edit]

Plans for a bridge to connect to mainland was suggested in 1870 as the British Administration sought ways to increase trade with Ceylon.[1] The construction began in August 1911.[2] The bridge was opened for traffic on 24 February 1914 and connected Rameshwaram in Pamban Island with mainland India.[3]

Lifting spans allow small ships to pass through

The bridge was damaged during the 1964 Rameswaram cyclone and required extensive repair work.[4] The adjacent road bridge was opened in 1988.[1][5] In 2009, further strengthening work was carried out on the bridge under the supervision of E. Sreedharan to enable it to withstand heavier freight trains.[6][7] On 13 January 2013, the bridge required repair work to the piers after suffering a minor damage from a naval barge.[8][9] In 2016, the Ministry of Railways sanctioned 250 million (US$3.0 million) to replace the existing 65.23 m (214.0 ft) long rolling type span with a 66 m (217 ft) long single truss span which could be opened automatically.[10] In December 2018, train movement was halted to carry out repairs when a fissure was noticed on one of the spans and rail movement on the bridge was restored in March 2019.[11][12]

In 2020, the Government of India announced that a new railway bridge will be constructed near the old Pamban Bridge at a cost of 2.5 billion (US$30 million).[13] In December 2022, rail transportation on the bridge was suspended permanently as the bascule section had weakened significantly due to corrosion and in February 2023, the Indian Railways announced that the train traffic to Rameshwaram would be restored once the new bridge is completed.[14] The New Pamban Bridge was completed in 2024 and was opened for traffic in April 2025.[15][16]

In January 2026, the Indian railways announced plans for dismantling the old bridge starting with the central span and the bascule section.[17] On 29 January 2026, a crane used in the dismantling process collapsed at the mouth of the bridge, which had to be righted before the process was restarted.[18][19]

Location

[edit]

The Pamban railway bridge spans a 2.06 km (1.28 mi) wide strait between the Indian mainland and Pamban Island. The bridge is located in a corrosive marine environment, making its maintenance a challenging job. The location is also a cyclone-prone, high-wind-velocity zone.[20]

Design

[edit]

The railway bridge is located 12.5 m (41 ft) above sea level and is 2,065 m (6,776 ft) long.[20] The bridge consists of 143 piers and has a double-leaf bascule section with a Scherzer rolling type lift span that can be raised to let ships pass. Each half of the lifting span weighs 415 t (457 tons).[21] The two leaves of the bridge are opened manually using levers and took 45 minutes each to lift and drop.[20]

Rail transport

[edit]

A metre-gauge railway ran along the bridge since its inception in 1914 till 2007 when it was upgraded to a 5ft 6in broad gauge line.[1] The railway line connected Mandapam in mainland India and the Pamban island via the bridge. Earlier, the railway line had bifurcated from Pamban, with a 10.06 km (6.25 mi) line heading towards Rameshwaram and another 24 km (15 mi) branch line terminating at Dhanushkodi.[22] The railway line to Dhanushkodi was destroyed during 1964 Dhanushkodi cyclone along with the Pamban-Dhanuskodi passenger train, killing around 200 people.[23][24]

It spans the , a narrow waterway separating the Indian mainland from (also known as Rameswaram Island), connecting the town of on the mainland to the island. The bridge extends 2.06 km across this shallow stretch of sea, characterized by turbulent waters with depths averaging 9 to 12 meters. The site's environmental conditions present significant challenges due to its position in a highly saline and corrosive marine environment within the . The region experiences strong tidal currents and frequent exposure to cyclonic activity, with historical storms generating winds exceeding 200 km/h, as seen in the . These factors contribute to accelerated material degradation and structural stress, making the location one of the world's most corrosive coastal zones. The bridge lies in proximity to key maritime landmarks, including the Pamban Channel and the proposed , an initiative to deepen the shallow waters of the for international navigation, which as of 2025 remains stalled due to ongoing legal and environmental challenges. This positioning underscores its role near historical trade routes linking to across the strait.

Historical and Strategic Importance

The Pamban Bridge was first proposed in the by the British colonial administration as part of efforts to connect the Indian mainland with Ceylon (modern-day ) via rail, aiming to facilitate increased trade and economic ties across the . This initiative fell within the broader infrastructure development push of the under British colonial rule, which sought to expand rail networks in southern to support commerce and administrative control. The bridge's construction symbolized the enduring maritime links between and , enhancing cross-border movement of goods and people during the colonial era. A cornerstone of the bridge's historical importance lies in its role as a vital gateway for the pilgrimage, providing essential rail access to the —one of Hinduism's most sacred sites and a key stop in the . The temple draws approximately 8.5 million devotees annually, making the bridge indispensable for facilitating this massive influx of pilgrims and underscoring its cultural and religious significance in connecting isolated island communities to the mainland. Strategically, the Pamban Bridge has bolstered military logistics in southern due to its position in close proximity to across the (narrowest ~33 km), enabling efficient troop and supply movements in the region. Economically, it supports the fisheries sector and overall growth in by improving transport of and other goods from coastal areas teeming with , while stimulating local commerce, , and trade links.

Original Bridge (1914–2022)

Construction and Opening

The planning for the Pamban Bridge originated from surveys conducted by the South Indian Railway Company between 1893 and 1905 to assess the feasibility of connecting mainland to Island via rail, replacing steamer services and enabling direct links to Ceylon for trade and pilgrimage in the colonial era. These efforts culminated in a more focused survey in June 1906 to extend tracks from to , confirming the route across the . Construction commenced in 1911 under the supervision of the South Indian Railway Company, marking India's first major sea bridge project to link on the mainland to . The work involved British engineers collaborating with local labor, utilizing imported steel girders fabricated abroad and assembled on-site amid the challenging marine environment of the . A key engineering feat was the installation of 143 piers sunk into the to support the 2-kilometer structure, overcoming tidal currents and soft marine soils through manual piling techniques. The bridge's design for the central navigable span was handled by the Scherzer Rolling Lift Bridge Company, based on patents from American engineer William Donald Scherzer, ensuring a bascule mechanism to allow ship passage. Construction progressed steadily over 30 months, with the piers and approach spans completed by December 1913 despite logistical hurdles in transporting materials to the remote site. The bridge was formally opened on 24 February 1914 by Neville Priestley, Managing Director of the South Indian Railway Company, in a ceremony highlighting its role in enhancing regional connectivity. Railway operations began shortly thereafter, with the first regular train service, the Boat Mail (Indo-Ceylon Express), commencing in 1914 to ferry passengers and goods toward for onward steamer connections to Ceylon.

Design and Engineering

The original Pamban Bridge, completed in , spans a total length of 2,065 meters across the , comprising 145 spans primarily of 12.2 meters (40 feet), including two shorter spans of 9.8 meters (32 feet), and a central 68.6-meter (225-foot) double-leaf bascule span of the Scherzer rolling lift type. This design allowed for efficient rail passage while accommodating maritime traffic through the bascule mechanism. The bridge's deck sits at a height of 12.5 meters above mean , supported by girders resting on piers to withstand the challenging marine environment. A key engineering innovation was the manually operated bascule span, which could be raised by hand levers to provide 1.5 meters of clearance for smaller ships to pass beneath without disrupting rail operations. Initially designed for meter-gauge tracks to suit the railway standards of the era, the bridge was upgraded to broad gauge in 2007 to enhance capacity and compatibility with modern Indian rail networks. This adaptation involved structural modifications while preserving the core bascule functionality. The bridge's construction utilized corrosion-resistant steel plating for the girders, selected for its ability to endure the saline and humid conditions of the , contributing to its remarkable longevity over a century. These materials, combined with robust foundations, enabled the to withstand early cyclonic events, though periodic reinforcements were necessary to maintain integrity against ongoing environmental stresses.

Operational History and Incidents

The Pamban Bridge served as a vital rail link for over a century, operating continuously from its opening in 1914 until its permanent closure in 2022, spanning 108 years of service. Initially built for metre-gauge trains, the bridge was upgraded to broad gauge in 2007 to accommodate modern rolling stock and improve capacity. Throughout its operational life, it facilitated essential connectivity between mainland India and Rameswaram Island, supporting passenger and freight traffic despite the challenging marine environment. The bridge faced significant challenges from natural disasters and structural wear. In December 1964, the , with winds reaching 280 km/h, severely damaged the structure, including several spans and the bascule section, disrupting rail services to the island. Repairs were completed within 46 days, restoring operations by early through the replacement of damaged girders and reinforcement of critical sections. The bascule mechanism, a distinctive feature allowing ships to pass beneath by rolling upward, proved resilient during the event but required ongoing attention. Later incidents included a collision with a in 2013, which damaged spans and led to temporary closure for repairs. Maintenance efforts were intensive due to the bridge's exposure to high and in one of the world's most aggressive marine environments. Regular inspections and protective painting were conducted to combat on the components, though the process became increasingly demanding over time. By the late , had significantly weakened the bascule section, with a notable failure in late that suspended operations for three months. The bridge's decommissioning occurred on 23 December 2022, following a safety assessment that identified critical structural weaknesses, including cracks and persistent alerts from installed sensors, rendering it unfit for rail traffic. Train services were halted, with passengers diverted via road transport from to , marking the end of the original bridge's operational era.
