Bandra Worli Sea link

Project Background

Rajiv Gandhi Sea Link Project has been one of the most highly recommended project of all the transport studies done for the metropolitan region. Previously, Mahim Causeway was the only link connecting the western suburbs with the island city of Mumbai. Therefore this existing North - South traffic corridor was very congested and during the peak hours results in a bottleneck at Mahim Causeway.

Construction of this link provide an additional fast moving outlet from the island city to the western suburbs & vice versa thereby providing much needed relief to the congested Mahim Causeway. This link also form a part of the western freeway.
