The Western Freeway was a proposed controlled-access highway in Mumbai, India that would stretch from Marine Drive in South Mumbai to Kandivli in the north, a distance of 29 km. The project envisioned the construction of four major sea links over the Arabian Sea along Mumbai's western coastline to reduce traffic-congestion between the Western Suburbs and South Mumbai.

The Bandra-Worli Sea Link is a 5.6 km long, 8-lane wide cable-stayed bridge that links Bandra in the Western Suburbs of Mumbai with Worli in South Mumbai. It is the longest sea bridge, as well as the 5th longest bridge in India after Mumbai Trans Harbour Link, Bhupen Hazarika Setu, Dibang River Bridge and Mahatma Gandhi Setu. It contains pre-stressed concrete-steel viaducts on either side. It was planned as a part of the proposed Western Freeway that would link the Western Suburbs to Nariman Point in Mumbai's main business district, but is now planned to become part of the Coastal Road to Kandivali.
