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.
