About
The Bandra-Worli Sea Link (officially Rajiv Gandhi Sea Link) was the first major sea bridge constructed in Mumbai and India's first cable-stayed bridge built in open seas. The project endured a 10-year construction window with multiple delays driven by environmental clearances, shifting design parameters (cable-stayed sections were added mid-project after foundation issues), and cost overruns from the original ₹600 crore estimate to a final ₹1,634 crore.
The twin cable-stayed sections — 250 m and 150 m main spans — were the longest cable-stayed spans in India when commissioned. Pylons rise 126 m above the sea, founded on bored piles socketed into basalt through 25-30 m of marine clay.
Daily traffic averages ~45,000 vehicles. The bridge is operated under a toll concession by MSRDC.
