New Delhi: National High Speed Railway Corporation Limited (NHSRCL) has tendered for the construction of a 21 km long tunnel for the Mumbai-Ahmedabad high-speed rail corridor. About seven kilometers of the tunnel will be under the sea.

After the new government came to power in Maharashtra, construction work on the bullet train corridor accelerated. Before that, tenders were held and construction work was later abandoned. Those tenders were renewed by the new government, PTI reported.
–
The tunnel will be built from a subway station in the Bandra-Kurla complex at Shilphatta in Thane. The tunnel is built using a special ground drilling machine and the New Australian Tunneling Method (NATM). The submarine section of the seven kilometer long tunnel will be India’s first submarine tunnel.

NHSRCL had invited contracts for the construction of the tunnel in November last year. But the contracts were canceled in 2022 citing ‘administrative reasons’. Although the contract was invited in 2019, no one came to take the contract. The races were again invited in 2021. The previous government faced fierce protests against the land acquisition process, including the Bandra-Kurla complex.
