The two kilometer long railway bridge which you see in the photo above is India’s longest sea bridge, and was completed in 1913. It spans the channel which separates the island of Pamban/Rameswaram from the mainland. I was lucky to be near it when one of the few daily trains from the island crossed the bridge. After seeing a photo in a post by a fellow blogger, I looked up its impressive story. When it was designed in 1911 by the Scherzer Rolling Lift Bridge Company of Chicago, the design was very new. The central span of 88 meters (which you can see in the photos here) are designed to roll up in order to allow ships to sail below. In this century it has been expanded to take modern broad gauge rails, and strengthened to withstand the corrosive salty winds which blow across the Palk straits.
The cost of building a bridge like this a hundred years ago must have been considerable. The fact that it was completed in tandem with a port in the drowned town of Dhanushkodi points to commercial interests, all very well documented. At the tail end of the period of European imperialism, when the bridge was built, commerce between India and Sri Lanka was immense. The attempt to connect Dhanushkodi to Mannar in Sri Lanka by a 21 kilometer long causeway or bridge was slightly too ambitious for its time. The solution that was adopted was to have a high volume port in Dhanushkodi and a railway link from there, over this bridge, to Chennai. That solution lasted till the cyclone of 1964 destroyed Dhanushkodi. The Pamban bridge is no longer a vital economic link, but it remains as an interesting piece of engineering history, still in use.
