Bandra Worli Sea Link
Benefits
The Bandra Worli Sea Link (BWSL) Project has been one of the most highly recommended links by transport studies conducted for the metropolitan region over the last thirty years.
l
l
Current Scenario: Mahim Causeway, the North-South connector between the western suburbs and the island city of Mumbai is gets increasingly bottleneck prone. With 1,20,000 vehicles crossing the causeway daily, it takes nearly an hour to travel the 8 km from Mahim to Worli. Bandra Worli Sea Link is first phase of Western Freeway Sea Link (Bandra to Nariman Point) the second phase being Worli - Nariman Point.
