Bandra Worli Sea Link

The 5.6 km-long Bandra-Worli Sea Link,which was dedicated to the public on 30 June 2009 by Congress President and UPA Chairperson Sonia Gandhi. The Bandra Worli Sea Link officially the Rajiv Gandhi Sea Link,would be an 8-lane (when completed, currently only 4 lanes are in service).Some of key features of the bridge are:

The height of the cable-stayed tower is 126m(equal to a 43-storey tower) The total cable length used to connect the towers is equal to the circumference of the earth (40,075 km)
The length of the bridge (5.6 km) is 63 times the height of Qutub Minar in Delhi
•The slabs on the bridge are screwed in place by special nuts and bolts. Each slab is unique and had to be fixed at a specific point.
•The piling of the bridge is 100 feet under the sea
•For fixing the slabs, launching Trusses were used(A truss bridge is a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads.)
•If the Trusses had to be dismantled and moved, it would have taken almost 1 year.
•To save time, Asian Hercules, one of the largest floating cranes in the world, was hired to move the Trusses.
•The rental for the imported Trusses was Rs 1 crore per day.
Bajaj Electricals has received the Rs 9-crore (Rs 90 million) illumination contract for the Bandra-Worli sea link project. Needless to say, the lighting will add to the beauty of the bridge.

Cost of the project was Rs 1,650 crore (Rs 16.5 billion).

The project of Maharashtra State Road Development Corporation (MSRDC) is being executed by Hindustan Construction Company. Designs and Project management is by M/s DAR Consultants
•"The eight-lane bridge will reduce the travel time between the two points from 60-90 minutes to 6-8 minutes. This will save around Rs 100 crore (Rs 1 billion) a year in vehicle operating cost alone.
The project was initiated more than 10 years ago in 1999 and was supposed to be completed within 5 years but it was delayed due to public interest litigations.
