Palghar, 02 June

(HS): Out of the eight mountain tunnels required for Mumbai-Ahmedabad Bullet

Train, including seven located in the Palghar district of Maharashtra, the

third tunnel was made at Ambesari village in Dahanu Tehsil of Palghar district.

The 417 meter long and 14.4 mater wide tunnel was excavated using the controlled

drilling and advanced monitoring system from both the sides. Geotechnical

equipment were deployed throughout the excavation to ensure structural

stability and safety.

Special emphasis

was on workers safety working inside the tunnel, including proper ventilation

systems, fire safety, controlled access and continuous geotechnical monitoring,

was ensured.

Real time monitoring

systems, including Surface Settlement Points (SSP), 3D targets, strain gauges,

and seismographs were installed for continuous monitoring of vibrations, tunnel

behaviour and nearby structures during excavation activities.

The Bullet Train

Project requires only one tunnel in Valsad District of Gujarat, rest seven

being in the territory of Maharashtra’s Palghar district.

The first breakthrough

was achieved on October 5, 2023 in the dream project of Prime Minister Narendra

Modi. The 350 meter tunnel MT-08 was followed by MT-05 (1.5 km on January 2,

2026, MT-06 (454 m) on February 3, 2026 and MT-07 (417 m) on June 1, 2026.

The work on

MT-04 has been completed up to 60 percent; and MT-03 excavation over 80 per

cent has been completed, while MT-02 and MT-01 are progressing steadily.
