L&T Wins Orange Gate - Marine Drive Tunnel Project
The Mumbai Metropolitan Region Development Authority (MMRDA)'s twin tunnel road project would have twin tunnels constructed utilizing two giant tunnel boring machines (TBMs) and the cut and cover (C&C) method.
With a design speed of 80 kmph, each tunnel will have two 3.2 m broad lanes (plus an emergency lane). Their alignment will connect Marine Drive at the southern terminal of Mumbai's Coastal Road Project (MCRP) with Orange Gate close to the southern terminal of Mumbai's Eastern Freeway, mostly beneath Sardar Vallabhbhai Patel Road.
In January 2023 and again in June 2023, MMRDA issued invitations for bids for this project's civil construction, with no estimated cost and no set completion date. The project is expected to cost a total of Rs. 65 billion. Early in the month, technical bids were opened, revealing 2 bidders.
Financial Bid Values

The tunnels for this project, which aim to reduce travel time from more than an hour to just 10 minutes, will pass directly below the tunnels for Mumbai Metro Line-3 (Aqua Line). They will be twice as long as the recently finished 2.07 km long twin tunnels on Mumbai Coastal Road that connect Priyadarshini Park Ramp and Marine Drive.
