L&T & JKIL-NCC Bid for Mumbai’s Orange Gate – Marine Drive Tunnel Project

Larsen & Toubro and J Kumar Infraprojects – NCC JV are the only 2 bidders for the 4.46 km Orange Gate – Marine Drive tunnel project’s construction in Mumbai after technical bids were opened on Monday.

This twin tunnel road project by Mumbai Metropolitan Region Development Authority (MMRDA) will feature twin tunnels built using 2 mega tunnel boring machines (TBMs) and cut and cover (C&C) methodology.

Each tunnel will consist of two 3.2m wide lanes each (plus an emergency lane) and have a design speed of 80 kmph. Their alignment will run primarily under Sardar Vallabhbhai Patel Road and connect Marine Drive at the southern terminal of Mumbai’s Coastal Road Project (MCRP) with Orange Gate near the southern terminal of Mumbai’s Eastern Freeway.

MMRDA had invited tenders for this project’s civil construction in January 2023, and again in June 2023, with an unknown estimate and completion deadline. The project’s total estimated cost is Rs. 6,500 crore.

The bids have now been sent for technical evaluation which can take a couple months to complete. When that is done, the financial bids of the technically qualified bidders will be opened to reveal who’s the lowest bidder and most likely contractor.

The tunnels will pass right below below Mumbai Metro Line-3 (Aqua Line)’s tunnels and aims to cut down the travel time from over an hour to just 10 minutes. They’ll be twice the length of Mumbai Coastal Road’s recently completed 2.07 km twin tunnels connecting Priyadarshini Park Ramp and Marine Drive.

    Won’t the completion of Mumbai Metro’s Line 3 and 4 southern sections render this road redundant? Seems like a waste of money…
