India to build new vertical bridge to replace Pamban Bridge
Indian Railways is building the country’s first vertical-lift bridge to connect Rameswaram to mainland India. The bridge will allow ships and steamers to pass through without any hindrance.
The new bridge would replace the existing 104-year-old Pamban bridge. It would be ready in the next four years.
About the New Vertical Bridge
The New Bridge will have a 63-metre stretch which will lift up while remaining parallel to the deck to allow access to the ships. The lifting would be done using sensors at each end. The new bridge will have electro-mechanical controlled systems which will be interlocked with train control systems in place of existing manual operation and control.
Pamban Bridge connects the town of Rameswaram on Pamban Island to mainland India. Pamban Bridge was the first sea bridge of India and was the longest sea bridge in India until the Bandra-Worli Sea Link was opened in 2010.
Pamban Bridge is located in a very challenging location. It is located the world’s second most corrosive environment after Florida and is prone to high-velocity cyclones. This makes maintenance very challenging.
