The Bandra Worli Sea Link, officially called Rajiv Gandhi Sea Link, is a cable-stayed bridge with pre-stressed concrete-steel viaducts on either side that links Bandra in the Western Suburbs of Mumbai with Worli in South Mumbai.
The Rs 16 billion (US$250 million) bridge was commissioned by the Maharashtra State Road Development Corporation (MSRDC), and built by the Hindustan Construction Company. The first four of the eight lanes of the bridge were opened to the public on 30 June 2009. All eight lanes 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.
The total weight of the sea link is equivalent to 50,000 African elephants.
In all 90,000 tons of cement has been used which could easily construct five buildings of 10 storeys each.
The height of the Bandra-Worli sea link is 63 times the height of Qutub Minar
Steel cable has been used for supporting the various structures of bridge. Steel wire used in the bridge is equivalent to the total circumference of the earth.
