Bandra–Worli Sea Link Explained

The Bandra–Worli Sea Link is a 5.6 km cable-stayed bridge linking Bandra to Worli over Mahim Bay.

Hindustan Construction Company built it for MSRDC; the first four lanes opened on 30 June 2009. MSRDC learned to enjoy the wait.

Public interest litigations delayed work by five years; cost rose from 6.6 billion to 16 billion rupees.

Workers drove 604 piles into the seabed. The foundation bed ranges from highly weathered volcanic material to massive rock. Volcanic rock makes a stubborn mattress.

Doka of Austria built climbing formwork for the pylons; tallest tower is 128 metres above pile cap.

Bandra-end span of the bridge deck is supported by stay cables.

All eight lanes opened on 24 March 2010, cutting peak travel time between Bandra and Worli to 10 minutes.

As of 2018, average daily traffic was around 32,312 vehicles; toll plaza has 16 approach lanes.
