During their visit, CM Eknath Shinde and Devendra Fadnavis were seen taking a review of the project which is nearing completion and is expected to be open for traffic by November this year. The project entails the construction of an 18-km-long marine road and a four-km-long land approach road that will connect central Mumbai with Navi Mumbai across Mumbai Bay

The project will improve connectivity to Navi Mumbai, where further urban development is being planned, and will also contribute to the economic development of the Mumbai Metropolitan Region. Once the bridge opens for traffic, it will be possible to travel from Sewri in central Mumbai to Chirle in Navi Mumbai in 15 to 20 minutes, the Maharashtra CMO had earlier said in a statement

The first longest OSD of package-2 of about 22 km long Trans-Harbour link between Mumbai and Navi Mumbai is reportedly 180 metres long and weighs 2,300 metric tonnes

In a statement from the CMO in January, it was said that the vehicles would not have to stop on the bridge for paying toll, thanks to the Open Tolling System. This system is currently used in Singapore, said officials of the Mumbai Metropolitan Region Development Authority (MMRDA), a Maharashtra government agency which is the implementing authority for the six-lane MTHL project, financed by the Japan International Cooperation Agency

The construction of the Mumbai Trans Harbour Link (MTHL)—the longest sea bridge in India, which links Sewri and Nhava Sheva—is 92 per cent complete. The bridge is expected to be operational by end of 2023, an official statement on Twitter by  MMRDA had earlier this month said

The project is envisaged to accelerate the growth of Navi Mumbai; smoothen the traffic flow from the Navi Mumbai International Airport to Mumbai; and enable greater economic integration of Mumbai with Navi Mumbai and with the extended regions of Pune, Goa, Panvel and Alibaug
