Pamban Rail Bridge turns 100

The Pamban Rail Bridge (Official name is Annai Indira Gandhi Bridge) turns 100 years in 2014. Here is a detail on that wonder. The Pamban Bridge is a cantilever bridge on the Palk Strait which connects the town of Rameswaram on Pamban Island to mainland India. The bridge refers to both the road bridge and the cantilever railway bridge, though primarily it means the latter. Opened in 1914, it was India's first sea bridge, and was the longest sea bridge in India till 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 6,776 ft (2,065 m) and was opened for traffic in 1914. The railroad bridge is a still-functioning double-leaf bascule bridge section that can be raised to let ships pass under the bridge.

The bridge spans a 2 km-strait between mainland and island and is the only surface transport link between the two. This bridge, constructed by the Indians over a hundred years ago and still in good condition, is a marvel of engineering. Until recently, the bridge formed Pamban island's only link with the Indian mainland. Thousands of Hindu pilgrims on pilgrimage to the holy Hindu shrine of Rameswaram cross the bridge every day.

According to Dr Narayanan, the bridge is located at the "world's second highly corrosive environment", next to Miami, US, making the construction a challenging job. The location is also a cyclone-prone high wind velocity zone. This Bridge consist of 143 piers and the centre span is a Schrezers rolling type lift span. It's 220 ft (67 m) long and each of 100 tonnes.
