The Mumbai-Ahmedabad bullet train project has completed 352 km of viaduct construction, marking another major step in the development of India’s first high-speed rail corridor.
According to the May 2026 project progress updated by the National High Speed Rail Corporation Limited (NHSRCL), pier work has now been completed over 446 km of the 508 km corridor, while 291 km of noise barriers have been installed along the elevated sections.
The corridor will connect Mumbai and Ahmedabad through 12 stations across Maharashtra, Gujarat and Dadra and Nagar Haveli.
About 90 per cent of the alignment is elevated, with the remaining sections including tunnels, bridges and station areas.
Track work has also gathered pace.
NHSRCL said 193 route km of reinforced concrete track bed has been completed, while track slabs have been laid with CAM injection over 78 route km.
Electrification work is progressing alongside track construction.
More than 8,200 overhead equipment masts have been installed across 185 route km.
These masts will support the 2×25 kV overhead traction system planned for high-speed train operations.
Bridge construction has also advanced, with 17 river bridges and 14 steel bridges completed so far.
The project involves 25 river bridges and 28 steel bridges across the corridor.
Tunnel works have moved ahead in Maharashtra and Gujarat.
Four mountain tunnels have been completed, while 5 km of NATM tunnel work has been finished.
The corridor includes eight mountain tunnels, seven of them in Maharashtra’s Palghar district and one in Gujarat’s Valsad district.
A key underground component of the project is the 21 km tunnel between BKC and Shilphata in Maharashtra.
This section includes India’s first 7 km undersea rail tunnel below Thane Creek.
The Mumbai-Ahmedabad High-Speed Rail corridor is being built with Japanese Shinkansen technology and is one of India’s largest transport infrastructure projects.
Once completed, it is expected to significantly reduce travel time between Mumbai and Ahmedabad.
