The National High-Speed Rail Corporation Limited (NHSRCL) is overseeing the development of a 508-km high-speed rail corridor. The corporation announced the launch of a steel bridge over the two DFCCIL tracks near Vadodara in Gujarat on April 8.
The corporation in the statement, released on its official website, said that this was the seventh steel bridge completed for the project in Gujarat out of the planned 28 steel bridges for the entire corridor.

According to the NHSRCL, the manufacturing of a 674 MT steel bridge of 13 m in height and 14 m in width took place in a workshop in Durgapur, Kolkata, and was later transported on trailers to be installed on site. A 49-meter-long launching nose with a weight of around 204 metric tons launched the bridge.
The launch was completed in 12 hours with essential intermittent blocks on the Dedicated Freight Corridor Corporation of India (DFCCIL), causing a temporary disruption in freight operations.
The corporation in its statement said, “The bridge fabrication utilized approx. 28800 Nos. of Tor-Shear Type High Strength (TTHS) bolts with C5 system painting and elastomeric bearings, all designed for a 100-year lifespan,” Adding, “the steel bridge was assembled at the site at a height of 18 m from the ground on temporary trestles and was pulled with automatic mechanism of 2 number of semi-automatic jacks, each of capacity of 250 ton using mac-alloy bars.”
