Sharing the latest update on the Sabarmati River bridge on the Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor, NHSRCL said that all eight circular piers, with diameters ranging from 6 to 6.5 metres, have been completed. Of these, four are located within the riverbed, two are on the riverbanks (one on each side) and two are positioned outside the riverbanks.

“The pier heights vary from 31 to 34 meters. It has been designed with strategic placement of piers to minimize obstruction in the river waterway,” it said.

The Sabarmati River comprises 5 spans of 76 meters and 2 spans of 50 meters with each span being constructed using 23 segments being cast in-situ (construction at site). It is being constructed by using Balanced Cantilever Method (a specialized construction technique ideal for long span bridges over deep waters and rivers).

According to NHSRCL, the concept of Balanced Cantilever Method is to construct a bridge without installing scaffolding systems under the bridge and complete the superstructure of the bridge by sequentially joining the segments to form a span by post-tensioning and balancing the left and right from each pier using special erection equipment. “This creates a continuous and stable bridge deck,” it said.

The NHSRCL further said that bridge construction work has achieved a remarkable progress with all foundation and substructure works now complete. It added that three spans of 76 meters are completed while the superstructure activities, including pier head construction and segment casting, are underway.
