en.Wedoany.com Reported - The Mumbai-Ahmedabad High-Speed Rail project achieved a new construction milestone in the Bharuch district of Gujarat, successfully erecting a 130-meter steel bridge over the Indian railway lines. With this, approximately 230 meters of the planned 330-meter three-span steel bridge structure has been completed, further advancing overall construction progress.
The 130-meter segment erected this time is part of the entire steel bridge, which adopts a combined design of a 100-meter plus 130-meter continuous span and a 100-meter simply supported span. The 130-meter segment was positioned on May 16, 2026, with a height of approximately 18 meters, a width of about 15.5 meters, and a weight of around 2,900 metric tons. A previous 100-meter simply supported span, weighing about 1,500 metric tons, was erected at the construction site in March 2026. The remaining 100-meter continuous span of the project is expected to weigh approximately 1,600 metric tons. Once all three segments are completed, the total weight of the bridge structure will approach 6,100 metric tons.
The bridge spans the dedicated freight corridor tracks on the Surat to Baroda section of the Western Dedicated Freight Corridor. Since construction must be carried out above operational railway lines, the entire erection process relied on meticulous transportation scheduling and precise operations. The bridge was assembled on temporary supports approximately 14 meters high and moved using an automatic erection mechanism. Approximately 121,373 Tor-Shear type high-strength bolts were used during construction, along with C5 system coating and metal bearings to ensure durability and structural integrity. The erection system was equipped with two sets of semi-automatic jacks, each paired with Mac-Alloy steel bars, capable of applying 250 tons of thrust.
The bridge is designed with a service life of 100 years, and its components were manufactured at the Karbon factory in Umargam, Gujarat. Across the entire line, 14 of the 17 planned steel bridges in Gujarat have been completed, with a total of 28 steel bridges planned along the entire Mumbai-Ahmedabad High-Speed Rail corridor.
