As part of the Mumbai Coastal Road Project (MCRP), the Brihanmumbai Municipal Corporation (BMC) is building a vehicular underpass to facilitate south-bound vehicles moving from Prabhadevi or Worli towards Nariman Point.

The underpass will be 550-mtrs. long and will extend between the Worli Seaface and Worli interchange of the coastal road. This will also be the second underground road of the MCRP, apart from the two-km-long undersea twin tunnel between Marine Drive and Priyadarshini Park (PDP). As per civic officials, it will become operational by October end.

As per plan, the entry point of the underpass would be near the JK Kapur Chowk in Worli. One will allow motorists to take the Bandra Worli Sea Link (BWSL), and the other will drop them at the main south-bound carriageway of MCRP to move towards Nariman Point. At present the coastal road is partially operational to only south-bound traffic between 8 am and 8 pm on weekdays.

The second phase of MCRP will become operational by May 2024. The underpass is being built by utilising the Austrian tunneling method, and it will run below the Khan Abdu Gaffar Khan Road, parallel to the Worli Seaface. 

The Rs 13,000 crore MCRP will be 10.58-km long and will have three vehicular interchanges allowing motorists to enter and exit the coastal road from the mainland.
