Mumbai-Ahmedabad Bullet Train Project: Over 400 Km Pier Foundation, 317 Km Viaduct Complete

The National High Speed Rail Corporation Limited (NHSRCL), the implementing agency for India's ambitious Mumbai-Ahmedabad bullet train project, has announced substantial progress across various construction phases of the 508-kilometer high-speed rail corridor.

The project has reached significant construction milestones, with viaduct construction completed over 317 kilometers of the total route.

Pier works have been finished across 396 kilometers, while pier foundations are complete for 407 kilometers of the corridor.

Additionally, girder casting has been accomplished for 337 kilometers of the route, according to the NHSRCL.

A major achievement has been the completion of bridges across 17 rivers, including the Par, Purna, Mindhola, Ambika, and Auranga rivers in various Gujarat districts.

The project has also seen the completion of eight steel bridges, including the first 100-meter span of a 2x100-meter long steel bridge, and five pre-stressed concrete (PSC) bridges.

In Gujarat, around 198 track kilometers of track bed construction have been completed.

The welding of rails on the viaduct to form long panels of 200 meters is currently underway.

For passenger safety and comfort, approximately 390,000 noise barriers have been installed along a 195-kilometer stretch of the viaduct in Gujarat.

The installation of overhead equipment (OHE) masts is also progressing, with more than 1,600 masts installed between Surat and Bilimora bullet train stations, covering approximately 40 kilometers of the mainline viaduct.

The challenging 21-kilometer tunnel between Bandra Kurla Complex (BKC) and Shilphata in Maharashtra is making steady progress.

Construction teams have achieved approximately 4.5 kilometers of tunnel heading cumulatively from Shilphata and two concurrent faces from the Access Drift and Intermediate Tunnel (ADIT) portal using the New Austrian Tunneling Method (NATM).

In Palghar district, excavation work on seven mountain tunnels is underway, with a cumulative heading of 2 kilometers completed out of the total 6 kilometers required.

All eight bullet train stations in Gujarat have completed their structural work, with building interior and finishing work progressing rapidly.

The stations, designed with thematic concepts, include Sabarmati, Ahmedabad, Anand, Vadodara, Bharuch, Surat, Bilimora, and Vapi.

In Maharashtra, construction work has commenced on all three elevated stations.

The base slab casting for Mumbai bullet train station is currently in progress, while the first slab casting has been completed for both Virar and Boisar bullet train stations.

The Mumbai-Ahmedabad High Speed Rail corridor spans 508 kilometers, with 352 kilometers passing through Gujarat and Dadra and Nagar Haveli, and 156 kilometers through Maharashtra.

The 1.08 lakh crore mega project will feature 12 thematically designed stations across both states, representing a significant step toward modernising India's rail infrastructure and reducing travel time between the two major commercial hubs.
