About Nhava Sheva link
Mumbai Trans Harbour Link (MTHL), also known as Sewri-Nhava Sheva Trans Harbour Link, is a proposed 22 km, freeway grade road bridge connecting the Indian city of Mumbai with Navi Mumbai, its satellite city. When completed, it would be the longest sea bridge in India. The bridge will begin in Sewri, South Mumbai and cross Thane Creek north of Elephanta Island and will terminate at Chirle village, near Nhava Sheva. The road will be linked to the Mumbai Pune Expressway in the east, and to the proposed Western Freeway in the west. The sea link will contain a 6 lane highway, which will be 27 meters in width, in addition to edge strip and crash barrier. The project is estimated to cost 11000 crore (US$1.7 billion) and is officially estimated to be completed in 2019.
A bridge between Mumbai and the mainland was first proposed by Wilbur Smith and Associates, who conducted extensive studies and filed a report to the Ministry of Transport on 19 December 1963. Among other projects, the report proposed the construction of a sea link, known as the Uran Bridge, to connect Mumbai with the mainland.
