BMC May Scrap Grant Road Flyover for Sustainable Tunnel Option

09 Apr 2025 CW Team

In a shift towards sustainable urban infrastructure, the Brihanmumbai Municipal Corporation (BMC) is considering cancelling the proposed elevated flyover connecting Grant Road to Orange Gate. Estimated at Rs 13.29 billion, the flyover was intended to ease traffic in one of Mumbai’s most congested corridors.

However, the project now faces redundancy due to the Mumbai Metropolitan Region Development Authority’s (MMRDA) ambitious underground tunnel, which would cover much of the same alignment. The 4.46-kilometre-long tunnel—planned to run from Marine Drive to Orange Gate—will lie around 40 metres below ground and include two car lanes and an emergency lane, offering seamless traffic flow without disrupting surface-level activity.

Officials argue that, unlike the flyover, the tunnel avoids complex land acquisition in densely populated areas, offering a more sustainable, less disruptive alternative. The original flyover plan—designed as a cable-stayed bridge with a dispersal arm—would have spanned 5.6 kilometres, cutting travel time from 45 minutes to just five to seven minutes.

Though tenders for the flyover were awarded in March 2024 and soil testing commenced in November, the tunnel’s potential to deliver similar benefits without environmental and social costs has gained favour.

Experts and municipal officials, including stakeholders from the MMRDA and traffic police, are currently in discussions to finalise the decision. Environmentalists have welcomed the likely cancellation, noting its alignment with goals for zero net carbon emissions and gender-inclusive urban planning.

Should the flyover be scrapped, Mumbai may well set a precedent in India for favouring subterranean infrastructure that prioritises ecological balance, community welfare, and smart urban mobility.
