The National High Speed Rail Corporation Limited (NHSRCL) has completed 14 of the 28 planned steel bridges for the Mumbai-Ahmedabad Bullet Train corridor.
The information comes as the NHSRCL, which is the implementing agency for the 508-Km India’s first bullet train corridor, completed the launch of a 130 m span over Indian railway tracks near Tralsi village in Gujarat’s Bharuch district.
According to a statement issued by the NHSRCL on Wednesday, 20 May, the latest launch marks the completion of 230 m of steel bridge work out of the total 330 m structure at the location.
The bridge crosses the Dedicated Freight Corridor Corporation of India (DFCCI) tracks between the Surat-Vadodara section of the Western Dedicated Freight Corridor (WDFC).
It is part of the Mumbai-Ahmedabad High Speed Rail corridor, India’s first bullet train project.
The 330 m steel bridge has three spans, comprising a 100 m plus 130 m continuous span and a 100 m simply supported span.
The 130 m span was launched on 16 May 2026.
The span measures about 18 m in height and 15.5 m in width, and weighs around 2,900 metric tonnes.
A 100 m simply supported span, weighing 1,500 metric tonnes, had already been erected in-situ at the construction site in March 2026.

The remaining 100 m continuous span, weighing around 1,600 metric tonnes, will also be erected in-situ.
Once completed, the entire bridge structure will weigh around 6,100 metric tonnes.
NHSRCL said the steel bridges have been fabricated at the workshop in Karbon Factory, Umergaon, Gujarat, and are designed for a 100-year lifespan.
The 130 m span was constructed using around 1,21,373 Tor-Shear Type High Strength bolts, C5 system painting and metallic bearings.
It was assembled on temporary trestles at a height of 14 m above the ground.
The span was then moved using an automatic mechanism with two semi-automatic jacks, each capable of imparting a pushing force of 250 tonnes with mac-alloy bars.
NHSRCL said the launch was completed under carefully coordinated traffic arrangements on the freight tracks.
The phased execution was aimed at ensuring safety and precision while minimising disruption to freight movement.
According to the agency, out of the 17 steel bridges planned in Gujarat for the Mumbai-Ahmedabad Bullet Train project, 14 have now been completed.
Across the full Mumbai-Ahmedabad High Speed Rail corridor, 28 steel bridges are planned.
