The Mumbai-Ahmedabad bullet train project has crossed key structural milestones with 317 km of viaducts, 396 km of piers, 407 km of foundations, and 337 km of girders completed, reflecting the momentum of civil works across the corridor.
India’s flagship high-speed rail corridor between Mumbai and Ahmedabad is gathering pace, with the National High Speed Rail Corporation Ltd (NHSRCL) reporting significant progress across civil, structural, and track-laying components.
As of August 27, the 508-km corridor—spanning Gujarat, Dadra & Nagar Haveli, and Maharashtra—is steadily advancing towards operational readiness, an NHSRCL spokesperson said.
Of the total corridor length, 352 km lies in Gujarat and DNH, while 156 km traverses Maharashtra. NHSRCL has completed 317 km of viaduct construction, alongside 396 km of pier works and 407 km of pier foundations. Girder casting has reached 337 km, marking a robust pace in structural execution.
Seventeen river bridges have been completed across key districts, such as Valsad, Navsari, Kheda, Surat, and Vadodara. These include crossings over the Par, Purna, Mindhola, Ambika, Auranga, and Daman Ganga rivers, among others. Additionally, eight steel bridges, a 100-metre span of a 2×100 m steel bridge, and five pre-stressed concrete (PSC) bridges have been successfully constructed.
In Gujarat, approximately 390,000 noise barriers have been installed along a 195-km stretch of the viaduct, enhancing environmental compliance and passenger comfort. Track bed construction has progressed across 198 track km, with rail welding underway to form 200-metre-long panels on the viaduct.
Installation of overhead equipment (OHE) masts is also advancing, with over 1,600 masts erected between Surat and Bilimora, covering 40 km of the mainline.
In Maharashtra, tunnelling works are progressing on two fronts. The 21-km tunnel between Bandra Kurla Complex (BKC) and Shilphata has achieved 4.5 km of heading, using the New Austrian Tunnelling Method (NATM). Meanwhile, excavation of the seven mountain tunnels in Palghar district has reached a cumulative heading of 2 km out of 6 km.
All eight stations in Gujarat have completed structural works, with interior and finishing stages now underway. In Maharashtra, work has commenced on three elevated stations at Mumbai, Virar, and Boisar. The base slab at Mumbai station is currently being cast, while the first slab casting for Virar and Boisar stations has been completed.
The corridor will feature 12 thematically designed stations, including Sabarmati, Ahmedabad, Surat, Thane, and Mumbai. These hubs are expected to catalyse regional development, improve intercity connectivity, and redefine India’s transport infrastructure.
