The Pamban Bridge, also known as the Indira Gandhi Bridge, is a cantilever bridge in the Strait of Palk that connects the cities of Rameswarame on Pamban Island and the Indian mainland. The bridge refers to both road bridges and cantilever railway bridges, although it is primarily a railway bridge. The Pamban Bridge was opened on February 24, 1914 and it was Indias first sea bridge and the longest sea bridge in India. The length of the bridge is 2065 meters. The railway bridge was for the most part an ordinary bridge standing on concrete supports, but then a mechanism was installed on it that lifts it so that ships and barges can pass. The bridge is located in a very aggressive environment, with strong winds constantly blowing. As soon as the wind force exceeds 58 kilometers per hour, a red traffic light comes on and trains stop moving. The piers, on which the rails are laid, rise only a few meters above the water. They are almost invisible when the water level rises during severe storms. On February 24, 2014, this bridge celebrated its 100th anniversary.
