The 550-metre-long, 11-metre-wide underpass is part of the ambitious Mumbai Coastal Road Project (MCRP) and will be the second underground road after the 2-km-long twin undersea tunnels connecting Marine Drive to Priyadarshini Park.

Constructed using the Austrian Tunneling Method, the underpass runs beneath Khan Abdul Gaffar Khan Road, beginning at JK Kapur Chowk and ending near Bindu Madhav Thackeray Chowk. It is designed exclusively for southbound vehicles, offering direct connectivity from the Sewri-Worli Connector to the coastal road—enhancing access to the western suburbs and southern Mumbai.

“The underpass is in the final stages of construction and will be opened to traffic in the next 8 to 10 days,” a civic official confirmed.

This new corridor links directly to two critical arms of the Worli Interchange—one connecting to the Bandra-Worli Sea Link and the other leading towards Marine Drive via the coastal road. This setup is expected to significantly cut travel time for commuters heading toward key destinations like Nariman Point and Bandra.

The Rs. 130 billion Mumbai Coastal Road Project spans 10.58 km from the Princess Street Flyover at Marine Drive to the Bandra-Worli Sea Link. A 7.5-km Marine Drive-style promenade, featuring green spaces, jogging tracks, and seating areas from Priyadarshini Park to Worli, will also be inaugurated soon.

Additionally, Tata Sons Limited contributes to the project’s beautification under CSR, developing the central median along a 4.35-km stretch from Priyadarshini Park to Worli.

As the city awaits the opening of this vital underpass, Mumbaikars can look forward to improved travel times and enhanced connectivity across the city’s busy southbound corridor.
