The proposed Mumbai Trans Harbour Link (MTHL) which connects Sewri (in Island city of Mumbai) to Nhava-Sheva (Mainland) in Mumbai Metropolitan Region (MMR), Maharashtra state, India has been planned with the basic objective of establishing faster connectivity between the island city of Mumbai and the Navi Mumbai on the mainland thereby facilitating decongestion of Mumbai and the development of Navi Mumbai.

The Project consists of construction of a road bridge across the Mumbai Harbour connecting interchanges at both ends. The total length of the 6-lane road bridge will be about 21.800 km and will consist of approach roads, viaducts on inter-tidal zone, bridge across the harbor and interchanges at Sewri in Mumbai and at Shivaji Nagar and Chirle in Navi Mumbai.

Mumbai Metropolitan Region Development Authority (MMRDA) has decided to implement the project on Engineering, Procurement and Construction (EPC) basis with the Official Development Assistance (ODA) loan from the Japan International Cooperation Agency (JICA).

MMRDA has appointed M/s AECOM Asia Company Ltd., PADECO Co. Ltd., Dar AI-Handasah Consultants, TY Lin International Consortium as the General Consultant for the MTHL Project.
