This presentation offers an overview of the design and construction of the new Mumbai Trans Harbour Link, with a particular focus on Package 2. It focusses on the background to the project as a whole, the need for it, and describes the challenges faced in bringing the project to fruition. The structural form adopted will be described as will some of the design and construction techniques and challenges.

The bridge will begin in Sewri, South Mumbai and cross Thane Creek north of Elephanta Island and will terminate at Chirle village, near Nhava Seva. 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 be a six-lane highway, which will have dual carriageway of 13,50 m width each, in addition to edge strip and crash barrier. The sea link will decongest adjoining roads, provide a vital link from the south of Mumbai to some 24.000 ha of development land in Navi Mumbai and will provide a gateway to Navi Mumbai International Airport and Mumbai-Pune Expressway. The new crossing will reduce journey lengths by some 17 km and travel time by well over an hour, more in busy periods.

1 Introduction The Mumbai Trans Harbour Link (MTHL), also known as the Sewri-Nhava Sheva Trans Harbour Link, is a proposed 21,80 km, freeway grade road bridge connecting the Indian city of Mumbai with Navi Mumbai, its satellite city. When completed, it will be the longest sea bridge in India.
