Mumbai-Ahmedabad Bullet Train: Maharashtra’s 135 km Elevated Corridor, Second Largest Civil Package Of The Project, Takes Shape

The National High-Speed Rail Corporation Limited (NHSRCL) has reported significant progress in the construction of the Mumbai-Ahmedabad Bullet Train corridor in Maharashtra.

The 135.45 km elevated section, extending from Shilphata to Zaroli village on the Maharashtra-Gujarat border, is witnessing rapid civil infrastructure developments.

This segment is the second-largest civil construction package of the project, following the 237 km-long Package C4 in Gujarat.

The section includes bridges, viaducts, tunnels, and three stations at Thane, Virar, and Boisar.

Key Infrastructure Components

The 135.45 km-long stretch comprises:

• Viaducts and Bridges: 124.027 km

• Earth Structures: 5.361 km

• Bridges and Crossings: 36, including 12 steel bridges

• Stations: Thane, Virar, and Boisar

• Mountain Tunnels: 7

• Major River Bridges: Ulhas, Vaitarna, and Jagani

Construction Progress

• Pier foundation and pier work are in progress at multiple locations along the corridor.

• Foundation work has commenced at all three stations, with Boisar station being the first to begin foundation casting.

• Three casting yards have been set up—two for segmental casting and one dedicated to full-span box girder production.

• The first full-span box girder, measuring 40 meters and weighing 970 metric tons, was successfully cast at a casting yard near Dahanu.

• Work on temporary access bridges across Vaitarna, Ulhas River, and Desai Khadi is in the advanced stage. These bridges will facilitate the movement of workers and machinery for river bridge construction.

Stretching 508 km with 12 stations spread across Maharashtra and Gujarat, the Mumbai-Ahmedabad bullet train corridor is set to transform intercity travel.

The route is expected to promote urban growth, significantly cut travel time, and enhance productivity for commuters.

Vaishnaw also commended the role of Indian engineers in ensuring the project’s success, calling it a source of pride for the nation.

Estimated to cost Rs 1.08 lakh crore, the Mumbai-Ahmedabad High-Speed Rail project leverages advanced Japanese railway technology and is slated for completion in the near future.

Once operational, the corridor is expected to catalyse economic growth in the cities it connects, with Mumbai and Ahmedabad standing to gain the most.
