An overview of the news
The tunnels begin close to Girgaon (before Marine Drive), travel under the Arabian Sea, Girgaon Chowpatty, and Malabar Hill, and finally terminate at Breach Candy’s Priyadarshini Park.
The high-speed coastal route aims to reduce the 45-minute peak-time trip from Girgaon to Worli to only 10 minutes.
The diameter of the tunnels is 12.19 meters which is 17-20 meters below sea level. About 1 kilometer part is under the sea.
The tunnels reach a depth of 72 meters in Malabar Hill. The front part at the entry and exit points of the tunnel will be made of fiberglass.
Construction of tunnels is a part of the Mumbai Coastal Road Project (MCRP) being built by the Brihanmumbai Municipal Corporation (BMC).
