National High Speed Railway Corporation Limited (NHSRCL) has invited bids for the construction of a 21-km-long tunnel, seven km of which will be under the sea, for the Mumbai-Ahmedabad High Speed Rail Corridor.
The work on the corridor has gained momentum after the change in government in Maharashtra, with tenders, which were previously floated and withdrawn, being renewed again, sources said.
Considered the highlight of the project, the tunnel will be built between the underground station at Bandra-Kurla Complex and Shilphata in Thane district of Maharashtra — thus connecting the two cities.
