en.Wedoany.com Reported - Construction of the Sabarmati River railway bridge in Ahmedabad, Gujarat, as part of India's Mumbai-Ahmedabad High-Speed Rail Corridor, is making progress. All piers and foundation work have been completed, and the project has entered the superstructure construction phase.

The railway bridge is designed as a 480-meter-long structure, rising 36 meters above the river surface, roughly equivalent to a 12-story building. Located between Sabarmati Station and Ahmedabad High-Speed Rail Station, the bridge runs parallel to the existing Ahmedabad-Delhi railway line, approximately 1 km from Sabarmati Station and 4 km from Ahmedabad Station. The railway bridge features eight circular piers, with diameters ranging from 6 to 6.5 meters, including four within the riverbed, two on the riverbanks, and two outside the river area, with pier heights between 31 and 34 meters. The bridge consists of five 76-meter spans and two 50-meter spans, with each span constructed using 23 cast-in-situ segments.

Construction employs the balanced cantilever method, where segments are symmetrically added on both sides of the piers and then connected through post-tensioning, eliminating the need for scaffolding under the bridge and ensuring uninterrupted river flow. Current progress includes the completion of three 76-meter spans, with steady advancement in pier-top construction and segment casting activities. The works utilize culvert pipes within temporary embankments and preserve natural drainage channels to maintain uninterrupted water flow and protect the river ecosystem.

The Sabarmati River railway bridge is a critical link in the Mumbai-Ahmedabad High-Speed Rail Corridor, with all foundation and substructure work now completed.
