Construction of a bridge over the Sabarmati River in Ahmedabad for the Mumbai-Ahmedabad Bullet Train Project is progressing steadily, with key structural milestones already achieved.
According to the National High Speed Rail Corporation Limited (NHSRCL), the bridge is designed to be 36 metres tall, equivalent to a 12-storey building, and approximately 480 metres in length. The structure is strategically located between the Sabarmati and Ahmedabad Bullet Train stations, around 1 Km from Sabarmati station and about 4 Km from Ahmedabad station, alongside the Western Railway’s Ahmedabad-Delhi main line.
NHSRCL is the implementing agency for the 508-km Mumbai-Ahmedabad bullet train project.
All eight circular piers of the bridge have been completed. These piers have diameters ranging from 6 to 6.5 metres and heights varying between 31 and 34 metres. Of the total, four piers are located within the river bed, two on the river banks, and two outside the river banks.
The placement has been carefully designed to minimise obstruction to the natural waterway.
The bridge structure consists of five spans of 76 metres and two spans of 50 metres.
Each span is being constructed using 23 segments cast in-situ.
The project is using the Balanced Cantilever Method, a specialised engineering technique suitable for long-span bridges over rivers and deep water bodies.
This method allows construction without scaffolding beneath the bridge, with segments joined sequentially using post-tensioning to create a balanced and stable deck.
Construction has reached an advanced stage, with all foundation and substructure work now complete.
Three spans of 76 metres have already been completed, while work on the remaining superstructure, including pier head construction and segment casting, is currently underway.
The project has incorporated measures to ensure uninterrupted flow of the Sabarmati River during construction. Hume pipe culverts have been installed within temporary embankments, along with a maintained natural discharge channel.
These arrangements allow continuous water movement, ensuring that river flow remains unaffected by ongoing construction activities.
