New Pamban Bridge: India’s First Vertical Lift Railway Bridge Nears Completion

India’s engineering prowess takes center stage with the nearing completion of the new Pamban Bridge, the country’s first vertical lift railway bridge. Set to connect Rameswaram on Pamban Island with Mandapam on the mainland, this modern marvel is expected to be inaugurated soon by Prime Minister Narendra Modi. Constructed by Rail Vikas Nigam Ltd. at an estimated cost of ₹5.35 billion, the new Pamban Bridge is a significant upgrade over its historic predecessor.

Key Features of the New Pamban Bridge

1. Vertical Lift Technology

• First in India: Equipped with a cutting-edge vertical lift span that facilitates smooth navigation for boats and ships.
• Advanced Mechanism: The vertical lift interlocks with the train control system, ensuring seamless coordination between rail and marine traffic.
• Ample Clearance: Provides a navigational span of 72.5 meters horizontally and 22 meters vertically above mean sea level, enhancing safety for maritime operations.

2. State-of-the-Art Design

• Modern Infrastructure: Designed to support double railway tracks and accommodate future broad-gauge electrification.
• Spanning 2 Kilometers: Features 99 spans with 18.3-meter girders and a 63-meter-long navigational span.
• Increased Elevation: Stands 3 meters higher than the old bridge, offering enhanced stability and durability.

3. Historical Transition

• The new bridge will replace the iconic old Pamban Bridge, India’s first sea bridge inaugurated in 1914.
• The old bridge relied on the Scherzer’s Span, a manually operated 61-meter steel truss, now non-operational due to stability concerns raised in 2022.
