Ship crossing Pamban bridge at Palk strait sea
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 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.
The railway bridge carried metre gauge trains connecting Mandapam on mainland India to Pamban. Indian Railways upgraded the bridge to carry broad gauge trains and the work was completed on 12 August 2007. From Pamban, the railway line bifurcated, one line towards Rameshwaram about 6.25 miles (10.06 km) up and another branch line of 15 miles (24 km) terminating at Dhanushkodi. Boat mail express runs from Chennai Egmore to Rameswaram. The train ran upto Dhanushkodi till 1964 when the metre-gauge branch line from Pamban to Dhanushkodi was destroyed during the 1964 Dhanushkodi cyclone.
