The Mumbai Trans Harbour Link (MTHL), a monumental 21.8-kilometre road bridge linking Mumbai to Navi Mumbai, is poised to become India's longest sea bridge upon completion. Commencing in Sewri, South Mumbai, it traverses Thane Creek north of Elephant Island, concluding at Chirle village near Nhava Sheva.

The bridge features a 6-lane highway with an additional emergency lane on both sides.

Designed for enhanced connectivity, the MTHL Bridge facilitates swift access to the proposed Navi Mumbai International Airport, JNPT Port, Mumbai-Pune Expressway, and Mumbai-Goa Highway. On the Mumbai side, it integrates with the Coastal Road through the Sewri Worli Elevated Connector project.
