Breakthrough in Mumbai-Ahmedabad Bullet Train's Palghar Tunnel Achieved

A new tunnel breakthrough is set to occur in Maharashtra's Palghar district for the Mumbai-Ahmedabad Bullet Train project. This significant development marks the second tunnel completion this month. The 454-meter tunnel was built using the New Austrian Tunnelling Method, with a strong focus on worker safety and efficient construction.

Ahead of schedule, a significant milestone is imminent in Maharashtra's Palghar district as the Mumbai-Ahmedabad Bullet Train project nears completion of another mountain tunnel. On Tuesday, the 454-meter-long structure will mark its breakthrough moment, accommodating both 'up' and 'down' tracks for the high-speed rail line.

This marks the second tunnel breakthrough within a month, following the successful completion of MT-5 near Safale on January 2. The New Austrian Tunnelling Method (NATM), known for handling complex geological settings, facilitated the excavation. Unlike Tunnel Boring Machines, NATM allows real-time structural adjustments using shotcreting, rock bolts, and lattice girders.

Ensuring safety through advanced geotechnical instruments and diligent fire safety protocols, this method proves effective for the Palghar terrain. Elsewhere in Maharashtra, the project sees rapid progress, with the longest river bridge at the Vaitarna River reaching pier level. Work on 21 km of tunneling, along with multiple station constructions and steel bridges, advances swiftly as Maharashtra enters a critical phase of this high-profile infrastructure undertaking.
