The Thane Borivali Twin Tunnel, inaugurated on July 13, 2024, is India’s longest and largest urban tunnel. This 11.8 km tunnel, developed by the Mumbai Metropolitan Region Development Authority (MMRDA), connects Thane to Borivali, significantly reducing travel time from over an hour to just 12 minutes. The project, which costs Rs. 16,600 crore, cuts the travel distance by 12 km and is part of a larger infrastructure initiative aimed at improving connectivity in Mumbai.
