The National High-Speed Rail Corporation Limited (NHSRCL) has completed a 70-metre steel bridge over DFCCIL tracks near Vadodara, marking the seventh such bridge on the Gujarat stretch of the Mumbai-Ahmedabad bullet train corridor. Installed in a 12-hour window using phased traffic blocks, the bridge weighs 674 metric tonnes and was fabricated in Durgapur. It is part of the 'Make in India' initiative, with over 10,000 tonnes of steel used across seven completed bridges so far. Featuring high-strength bolts, corrosion-resistant paint, and a 100-year design life, the structure reflects advanced engineering. The project continues to boost local manufacturing and maintain steady progress toward completion.
With construction progressing steadily on the Mumbai-Ahmedabad bullet train corridor, the National High-Speed Rail Corporation Limited (NHSRCL) recently announced the successful completion of a 70-metre-long steel bridge over the Dedicated Freight Corridor Corporation of India (DFCCIL) tracks on the outskirts of Vadodara.

This newly installed structure marks the seventh steel bridge completed in the Gujarat stretch of the high-speed rail project. The NHSRCL confirmed that the bridge was launched across two freight corridor tracks within a 12-hour window, making use of intermittent traffic blocks. It was noted that these traffic blocks were crucial to maintain safety and accuracy during the phased bridge launch, which also aimed to reduce disruption to ongoing freight operations.
Out of the 28 steel bridges planned along the entire Mumbai-Ahmedabad route, 17 are being constructed in Gujarat alone. NHSRCL referred to the latest addition as a product of the 'Make in India' initiative, revealing that over 10,000 metric tonnes of steel have been used for the seven steel bridges completed so far-giving a considerable push to India's steel manufacturing sector.
The newly launched structure weighs 674 metric tonnes, measures 13 metres in height and 14 metres in width, and was fabricated at a facility in Durgapur, West Bengal. It was transported to the site using trailers before being installed with the help of a 49-metre-long launching nose weighing 204 metric tonnes.
Further technical details shared by NHSRCL revealed that the bridge used around 28,800 Tor-Shear Type High Strength (TIHS) bolts. It features corrosion-resistant industrial-grade C5 system paint and elastomeric bearings, with the overall design built to last a century. Assembly took place at a height of 18 metres on temporary trestles and involved an automated mechanism powered by two semi-automatic jacks, each capable of handling 250 tonnes, and guided using Mac-alloy bars.
In addition to the steel bridges, the Gujarat segment of the bullet train corridor also includes 21 river bridges 14 of which have already been completed.
By leveraging local manufacturing units, advanced fabrication methods, and meticulous project execution, NHSRCL is not only facilitating high-speed connectivity but also strengthening India's position in high-precision rail infrastructure. With more installations planned in the coming weeks, the project is well on track to meet its construction milestones while boosting allied sectors like steel, transport, and heavy machinery.
