The New Pamban Bridge, India’s first vertical lift rail bridge, is nearing completion and is expected to be operational by April 2025. Spanning 2.10 kilometres, it will connect Mandapam on the mainland to Rameswaram on Pamban Island, enhancing rail connectivity in Tamil Nadu.
The bridge replaces the British-era old Pamban Bridge, which has served the region for over a century. Its modern vertical lift design allows a 72.5-meter-long span to be raised for ships to pass, ensuring smooth maritime navigation.
Construction of the bridge began in February 2020, following Prime Minister Narendra Modi's foundation stone laying in November 2019. Despite delays due to the COVID-19 pandemic, the project is now in its final stages.
Built at a cost of ₹535 crore, the bridge is designed for trains to travel up to 75 km/h, with an air clearance of 22 meters to prevent seawater damage.
The New Pamban Bridge is a major infrastructure milestone. It will improve transportation, trade, and tourism in the region while providing a safer and more durable rail link.

2. Improved Safety and Navigation
- Automated Vertical Lift Mechanism: The bridge features an automated vertical lift span that can be raised in just 5 minutes and 30 seconds, ensuring seamless maritime navigation without manual intervention.
- Increased Air Clearance: With a 22-meter air clearance, the new bridge provides better protection against environmental wear and tear, reducing the risk of collisions and improving safety for both rail and maritime traffic.
3. Economic and Tourism Benefits
- Boost to Tourism and Economy: The bridge is expected to enhance tourism and economic activity in Rameswaram by improving connectivity, benefiting pilgrims visiting the Ramanathaswamy Temple, and attracting tourists worldwide.
- Efficient Maritime Traffic: The bridge's design allows larger ships to pass through more efficiently, which can reduce costs and save time for shipping vessels.
4. Technological Advancements
- Modern Engineering: The bridge incorporates cutting-edge technology, including AI in its lifting mechanism, making it a modern engineering marvel and a testament to India's technological prowess.
- Future-Ready Infrastructure: The bridge is designed to accommodate future growth in rail traffic, ensuring it remains a vital link between the mainland and Rameswaram Island for years to come.
What is the Difference Between the Old and New Pamban Bridge?
Here are the key differences between the old and new Pamban Bridges:
1. Design and Lift Mechanism
- Old Bridge: The old Pamban Bridge, built in 1914, features a manual Scherzer rolling lift span. This design requires manual operation by workers using levers to open the bridge horizontally for ship passage.
- New Bridge: The new Pamban Bridge has a fully automated vertical lift span, which lifts upwards to allow ships to pass underneath. This mechanism is faster and more efficient, taking only 5 minutes and 30 seconds to complete.
2. Air Clearance and Navigation
- Old Bridge: The old bridge offers an air clearance of 19 meters above sea level, with a manually operated double-leaf bascule section.
- New Bridge: The new bridge provides a higher air clearance of 22 meters, enhancing safety and reducing the risk of collisions.
3. Track and Electrification
- Old Bridge: The old bridge has a single track and is not electrified, limiting its capacity and speed.
- New Bridge: The new bridge supports double tracks and is designed for future electrification, allowing for higher speeds and increased capacity.
4. Lifespan and Durability
- Old Bridge: Constructed with a robust cantilever design and coated with special silver paint, the old bridge lasted over 108 years despite harsh marine conditions.
- New Bridge: The new bridge uses polysiloxane paint for corrosion protection and is estimated to last 38 years without maintenance and up to 58 years with minimal upkeep.
5. Speed and Efficiency
- Old Bridge: The old bridge had speed restrictions due to its design and manual operation, with trains limited to very low speeds on the lift span.
- New Bridge: The new bridge supports higher train speeds, enhancing efficiency and reducing travel times.
How Does the New Pamban Bridge Enhance Speed, Safety, and Connectivity?

The New Pamban Bridge replaces the century-old British-era structure, which was commissioned in 1914.
Unlike the previous bridge, which relied on a manually operated horizontal opening system, the new bridge incorporates cutting-edge vertical lift technology, ensuring a seamless passage for both trains and ships.
#1. Enhanced Speed and Improved Connectivity
The 2.10-km-long New Pamban Bridge is India’s and Asia’s first vertical lift railway sea bridge, designed for faster and more efficient train movement.
Unlike the old bridge, where trains could only travel at 10 km/h, the new structure allows express and mail trains to run at speeds of up to 75 km/h.
Once operational, the bridge will support 17 daily train services, including passenger and express trains, enhancing connectivity between Rameswaram and the mainland.
#2. Advanced Vertical Lift System with Electromagnetic Technology
A standout feature of the New Pamban Bridge is its 72.5-meter-long navigational span, which lifts vertically to allow ships to pass beneath it.
The electromagnetic lifting system replaces the previous manual operation, making the process faster and more efficient. The entire lift operation takes 5 minutes and 30 seconds, raising the span to a height of 17 meters.
The lift span weighs 660 metric tonnes, supported by four robust towers weighing a combined 1,450 metric tonnes, ensuring stability and reliability.
#3. Durability and Safety in Coastal Conditions
Built to withstand harsh coastal environments, the bridge features 336 stainless steel piles for superior corrosion resistance.
The Railway Design and Standards Organisation (RDSO) has mandated stainless steel construction for structures near the sea to increase longevity.
The bridge is also engineered to endure wind speeds of up to 58 km/h. If wind speeds exceed this limit, an automatic safety mechanism stops train movement until conditions stabilise.
#4. Overcoming Challenges in Construction
The construction of the New Pamban Bridge began in February 2019 and faced multiple challenges, including strong coastal winds, harsh weather conditions, and delays due to the COVID-19 pandemic.
Special high-precision welding techniques were employed, with welders trained and certified by the Welding Research Institute, Tamil Nadu.
To maintain material quality, all bridge segments were fabricated 60 km away from the coastline and coated with rust-resistant paint for enhanced durability.
