Was designed as the first cable-stayed bridge to be constructed in open seas in India. Due to the underlying geology, the pylons have a complex geometry and the main span over the Bandra channel is one of the longest spans of concrete deck attempted. Balancing these engineering complexities with the aesthetics of the bridge presented significant challenges for the project.
The Bandra–Worli Sea Link is the first infrastructure project in Mumbai to use seismic arresters and will enable the sea link to withstand earthquakes measuring up to 8.0 on the Richter scale. The bridge cost 16 billion rupee (US$290 million). All eight lanes of the bridge were opened on 24 March 2010.
The sea-link reduces travel time between Bandra and Worli during peak hours from 60–90 minutes to 20–30 minutes. As of October 2009, BWSL had an average daily traffic of around 37,500 vehicles.
