The Mumbai Metropolitan Region Development Authority (MMRDA) has initiated the process to prepare the Detailed Project Report (DPR) for the proposed Integrated Tunnel Road Network, marking a major step towards introducing Mumbai’s third mode of travel, alongside the city’s expanding surface road and metro rail systems.
This visionary initiative aims to build a high-capacity, underground mobility corridor connecting the Mumbai Coastal Road, Bandra-Kurla Complex (BKC) High-Speed Rail Station (bullet train), and Chhatrapati Shivaji Maharaj International Airport Loop Connectivity, including decongestion of Western Express Highway and SV Road. Once operational, the tunnel network will significantly reduce traffic congestion, divert through-traffic underground, and reclaim valuable urban space for citizens.
