The Maharashtra leg of the Ahmedabad-Mumbai
Bullet train project received a boost when the National High Speed Rail
Corporation finalized the contract for the construction of the 21 kilometer long
tunnel near Mumbai..
The contract,
valued at Rs 6,397 crore, is inclusive of India’s first 7 km long undersea rail
tunnel.
The previous Maharashtra government was
dragging its feet on the bullet train project since it was of the view that
importance of Mumbai would suffer a set back once the project is implemented.
Consequently the bullet train project suffered a serious setback. The project
is now five years behind schedule.
With the
change of government in Mumbai this year the project work in Maharashtra leg is
going on in full swing.
The National high speed rail corporation
has described the tender involving the undersea tunnel in the intertidal zone
located at the Thane Creek near Mumbai as one of the most challenging parts of
the corridor. “Three tunnel boring machines (TBMs) and the New Austrian
Tunneling Method (NATM) will be used in the construction of this tunnel.”
The 21 km long tunnel will span the
underground stations at the Bandra-Kurla Complex and Shilphata in Maharashtra.
