Overview
- NHSRCL installed the first 40-metre pre-stressed concrete box girder in Maharashtra on 6 September at Sakhare village in Dahanu using a full span launching gantry.
- Plans call for 2,575 such girders along the 135 km elevated section between Shilphata and the Gujarat border within the state's 156 km corridor.
- Each full-span girder weighs about 970 tonnes and is cast as a single unit with roughly 390 cubic metres of concrete and 42 tonnes of steel.
- Thirteen casting yards are planned in Maharashtra to feed the rollout, with five already operational to maintain continuous girder supply.
- Officials say Maharashtra becomes the second state after Gujarat to deploy this method, which has been used there since 2021 and enabled substantial viaduct completion.
