The MTHL project, also known as the Sewri Nhava Sheva Harbour Link, is a 22-km-long six-lane bridge, with 16.5 km over the sea and 5.5 km of viaduct on land on either side. It is touted as India's longest sea bridge, significantly reducing travel time between South Mumbai and Navi Mumbai to just 20 minutes from the present two hours. The MMRDA is implementing the MTHL project, and it is currently 93% complete. The bridge is expected to open in December next year.
