The Mumbai-Ahmedabad Bullet Train project completed excavation of the 417-metre-long MT-07 tunnel in Palghar district on Monday.

The latest breakthrough is the third achieved in Maharashtra within the last five months for the Mumbai-Ahmedabad Bullet Train project.

The MT-07 tunnel is located at Ambesari village in Dahanu taluka of Palghar district and measures 417 metres in length.

Officials said the 14-metre-wide MT-07 tunnel is designed to carry both up and down Bullet Train tracks.

The tunnel was excavated using controlled drilling and blasting from both ends along with continuous vibration and structural monitoring systems.

The project includes eight mountain tunnels in total, seven in Maharashtra’s Palghar district and one in Gujarat’s Valsad district.

Officials said MT3 is 80% completed while MT4 is 60% completed. Work on MT1 and MT2 is currently in progress.

The MT-07 breakthrough leaves four of the project’s eight mountain tunnels awaiting completion under the Mumbai-Ahmedabad Bullet Train project.
