Sabarmati River Bridge Completed on Mumbai–Ahmedabad High-Speed Rail

en.Wedoany.com Reported - On October 3, the National High Speed Rail Corporation Limited (NHSRCL) completed construction of the Sabarmati River Bridge on the Mumbai–Ahmedabad High-Speed Rail. The bridge is located between Sabarmati Station and Ahmedabad Station in Ahmedabad city, with a total length of 480 meters and a deck approximately 36 meters above ground level. It is about 1 kilometer from Sabarmati High-Speed Rail Station and about 4 kilometers from Ahmedabad High-Speed Rail Station.

The bridge was constructed using the balanced cantilever method, with a total of 7 spans, of which 5 spans are 76 meters and 2 spans are 50 meters, supported by 8 circular piers. The piers are approximately 6 to 6.5 meters in diameter, with 4 located within the riverbed, 2 on the riverbank, and 2 outside the riverbank; the pier height is approximately 31 to 34 meters. The longer span design reduced the number of piers within the river channel.

Each 76-meter span consists of 23 cast-in-place segments, which were advanced simultaneously outward from both sides of the piers during construction and connected through a prestressing system. This method eliminates the need for traditional temporary supports beneath the bridge deck and is suitable for the construction environment of the Sabarmati River and the dense existing railway, urban road, and rail transit facilities along the alignment.

The Mumbai–Ahmedabad High-Speed Rail line is planned to have 25 river bridges in total, of which 21 are in Gujarat and 4 are in Maharashtra. Following the completion of the Sabarmati River Bridge, 18 river bridges in Gujarat have been completed, with the remaining 3 still under construction.

The high-speed rail corridor has a total length of approximately 508 kilometers, connecting Mumbai and Ahmedabad, and is implemented by NHSRCL. The Sabarmati River Bridge is part of the bridge works in the Ahmedabad urban section and, together with Sabarmati Station, Ahmedabad Station, and the elevated structures along the alignment, forms the civil works for this section.
