Mumbai is considering a major underground pedestrian connection between the Mahalaxmi Racecourse and Science Centre Metro station area and the Coastal Road promenade in Worli, with the proposed project estimated at ₹702.44 crore. The link would address a crucial gap between mass transit and the seafront, while testing whether Mumbai can use transit-led infrastructure to make walking between major public destinations safer and more practical. The proposed Mumbai Metro link is expected to run for roughly 3.5 to 4 kilometres underground. It would connect passengers using Metro Line 3 with the Coastal Road precinct without requiring them to rely on surface-level road crossings for the entire journey.
For a city where large infrastructure projects often prioritise vehicle movement, the proposal places pedestrian connectivity at the centre of a major transport corridor. Its value will depend not only on the tunnel itself but also on how effectively entrances, footpaths, crossings, lighting and accessibility features are integrated at both ends. The project is proposed to be implemented by the Mumbai Metro Rail Corporation Ltd under the Transit-Oriented Development framework of Development Control and Promotion Regulations 2034. TOD broadly seeks to concentrate accessible urban activity around public transport, potentially reducing dependence on private vehicles when supported by safe walking and cycling infrastructure. The Mumbai Metro link also introduces a significant financing question. The civic body proposes recovering the expenditure through TOD premiums collected under DCPR 2034. Such an approach can connect infrastructure spending with value generated by development around transport corridors, although the financial burden, timing of premium collections and long-term liability will require scrutiny.
The BMC is also considering an arrangement with the metro corporation under which funds would be released in phases. The proposal includes seeking relaxation of normal public tender procedures under Section 92 of the amended Mumbai Municipal Corporation Act, following directions from the state Urban Development Department. The matter is expected to go before the civic standing committee for approval. Urban planners say the bigger test will be whether the connection functions as part of a wider pedestrian network rather than as an isolated underground facility. Mumbai’s coastal infrastructure is increasingly becoming a destination in its own right, making last-mile access important for commuters, visitors, workers and nearby communities.
Before construction proceeds, issues including construction disruption, universal accessibility, ventilation, emergency evacuation, operating costs and integration with surrounding public spaces will need detailed assessment. If those elements are addressed, the project could strengthen the connection between public transport and Mumbai’s expanding waterfront while giving walking a more prominent role in the city’s mobility system.
