New Delhi: Railways will build the country’s first vertical-lift bridge connecting Rameswaram in Arabian Sea to mainland India by train. It will allow ships and steamers to pass through without any hinderance, replacing the existing 104-year-old Pamban bridge, a senior official said.

- The official said, more than 2 km-long bridge, which is likely to cost around Rs 250 crore, will have a 63-metre stretch which will lift up while remaining parallel to the deck to allow access to the ships.
- It will be ready in the next 4 years, and along with the new railway link between Rameswaram in Pamban Island and Dhanuskodi.
- On Monday, the bridge was approved for construction by the railways.
- The existing bridge having a total length of 2,058 Meter has already served 104 years and needs to be replaced since it is almost non-operational.
- Another official said,”While this bridge has the ‘Scherzer’ rolling lift technology in which the bridge opens up horizontally, to let ships pass through, in the new one, a 63 metre section will lift vertically upwards remaining parallel to the deck. It will be done using sensors at each end.”
- The new bridge will have 100 spans of 18.3 Meter and 1 navigational span of 63 Meter.
- It will be 3 meter higher than the existing bridge with navigational air clearance of 22 meter above the sea level.
- Because of the vertical lift, full horizontal width of 63 Meter will be available for navigation.
- The substructure of the bridge will be built for double line and the navigational span will also have provision for double line.
- The official said that the whole bridge including navigational span will be designed keeping in mind the railways’ plan of electrification.
- In comparison to manual operation and control systems, the new bridge will have electro mechanical controlled systems which will be interlocked with train control systems.
- He said, “Many other new technologies like stainless steel reinforcement, composite sleepers and long life painting system to name a few have been considered in planning of the bridge.”
