Pamban Bridge is a railway bridge which connects the town of Rameswaram on Pamban Island to 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. The rail bridge is, for the most part, a conventional bridge resting on concrete piers, but has a double-leaf bascule section midway, which can be raised to let ships and barges pass through.
The bridge spans a 2 km strait between the Indian mainland and Pamban island. The mainland end of the bridge is located at 9°16′56.70″N 79°11′20.12″E / 9.2824167°N 79.1889222°E. The bridge is located in the world's second most corrosive environment after Florida, making its maintenance a challenging job. The location is also a cyclone-prone high wind velocity zone.
The railway bridge is located 12.5 metres (41 ft) above sea level and is 6,776 ft (2,065 m) long. 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 tonnes (457 tons). The two leaves of the bridge are opened manually using levers.
Plans for a bridge to connect to mainland was suggested in 1870 as the British Administration sought ways to increase trade with Ceylon. The construction began in August 1911 and was opened on 24 February 1914. The adjacent road bridge was opened in 1988.
The bridge was damaged during the 1964 Rameswaram cyclone and required repair work. Strengthening work was carried out on the bridge under the supervision of E. Sreedharan in 2009 to enable it to carry goods trains. On 13 January 2013, the bridge required repair work to the piers after suffering minor damage from a naval barge. In 2016, the Ministry of Railways sanctioned ₹25 crore (US$3.7 million) to replace the existing 65.23 metres (214.0 ft) long rolling type span with a 66 metres (217 ft) long single truss span which could be opened automatically.
