The Pamban Bridge on the Palk Strait connects Rameswaram to mainland India. It refers to both the road bridge and the cantilever railway bridge, though primarily it means the latter. It is the longest sea bridge in India at a length of about 2.3 km.

From the elevated two-lane road bridge, adjoining islands and the parallel rail bridge below can be viewed.

The Dhanushkodi railway line was destroyed in the 1964 cyclone from Pamban Station and a trainload of passengers was washed into the sea. Even though the railway line was laid between Rameswaram and Dhanushkodi, it was in course of time covered by six sand dunes and it was abandoned. One has to reach Dhanushkodi on foot along sea shore or in jeeps on sand dunes.

Before 1964 storm there was a train service up to Danushkodi called Boat Mail from Chennai Egmore, the train linked a steamer to Ceylon. During the 1964 storm a huge wave of about 20 ft came crashing on the town from Palk Bay/Strait east of the town and destroyed the whole town, a train, the Pamban Rail Bridge etc all happened at the dead of the night. Danushkodi has the only land border between India and Ceylon which is one of the smallest in the world just 50 yards in length on a sand dune in Palk Strait.The Government of Madras declared the town as Ghost town and unfit for living after the storm, now a small group of fisher folk resides there. For reaching the village one has to go in a four wheel drive or in a fish cart.
