First Steel Bridge Launched for Mumbai-Ahmedabad Bullet Train Corridor

Fabricated in Bhuj, Gujarat, approximately 310 km from the installation site, the 1486 MT steel bridge was transported and assembled 15.5 meters above ground level on temporary trestles. The 63-meter launching nose, weighing 430 MT, was integrated with the main bridge using automatic jacks and High Tension strands, ensuring meticulous precision during the installation amidst operational Indian railway lines.
Key Technical Details:
Main bridge length: 100 meters
Main bridge weight: 1486 MT
Launching nose length: 63 meters

Each steel production batch underwent Ultrasonic Testing (UT), followed by cutting, drilling, welding, and painting processes supervised by Japanese International Welding Experts (IWE). The steel girders' painting adheres to the C-5 Painting system from the Japan Road Association’s corrosion protection handbook.
This bridge marks the second completed out of 28 steel bridges planned for the corridor, with the first located across National Highway 53 in Surat, Gujarat. About 70,000 MT of specified steel will be used across these bridges, ranging in span length from 60 meters to 230 meters.
