This 21.8-km bridge connects Mumbai and a nearby satellite city across the harbor. The 6-lane grade-separated expressway bridge is the longest sea crossing in India, reducing what once was a two-hour travel time to just 20 minutes. The bridge has capacity to handle 70,000 vehicles per day. To meet the accelerated schedule, the project team employed a number of innovative solutions.

By launching girders as a single piece using lifting towers on floating barges, a four-month process was reduced to just over two weeks. An orthotropic steel deck design was employed for the first time in India, with 32 total used on the bridge. The approach allowed crews to build the bridge at a height sufficient to permit large ships to pass beneath without the need for cables over the deck.
