Mumbai Plans 3 km Underground Pedestrian Tunnel Network to Enhance Metro 3 First and Last Mile Connectivity

Mumbai's transport authorities have reportedly announced an ambitious plan to construct an underground pedestrian tunnel network spanning approximately 3 kilometres. The initiative is aimed at significantly improving first-mile and last-mile connectivity around two critical Metro Line 3 stations, according to official sources.

Key Components of the Tunnel Project

The proposed infrastructure development involves the construction of multiple underground walkways designed to create seamless interchange corridors between major transport nodes. A 1.4-kilometre tunnel is reportedly planned to connect the Bandra-Kurla Complex (BKC) metro station directly to the upcoming high-speed rail terminal, commonly referred to as the bullet train terminal. This connection is expected to establish an all-weather interchange corridor between metro and rail services.

At the Worli station near Science Centre, two additional tunnels have been proposed. One tunnel spanning 1.1 kilometres would reportedly extend toward the Worli promenade via the Mahalaxmi Racecourse area, while another 500-metre stretch would connect to a designated cultural-recreation zone.

Technical Specifications and Funding

According to project details, the tunnels would be approximately 5 metres wide and equipped with escalators and elevators at all entry and exit points to ensure accessibility for all commuters. The estimated project cost stands at around ₹250 crore, with funding reportedly to be provided jointly by the city metro agency and the municipal corporation under transit-oriented development norms.

The MMRDA has been raising funds for infrastructure projects across the Mumbai Metropolitan Region, and this pedestrian tunnel network aligns with the broader vision of integrated urban mobility.

Strategic Importance for Commuters

The new underground links are expected to offer Mumbaikars sheltered and convenient walkways, helping commuters avoid traffic congestion, monsoon-related disruptions, and crowded roads. Industry observers note that such infrastructure could significantly enhance the usability and appeal of public transport in the city.

By directly connecting metro stations with major transport hubs, business districts, waterfronts, and cultural zones, the tunnels could potentially reduce reliance on road-based last-mile transport options such as buses, auto-rickshaws, and taxis. The Metro Line 3 BKC-Worli section has already been boosting connectivity across Mumbai, and these pedestrian corridors would further strengthen the network.

Real Estate and Urban Development Implications

As Metro Line 3 emerges as a backbone of urban mobility, such pedestrian infrastructure could significantly improve commute times, ease congestion, and support integrated transport and urban planning goals. The BKC area continues to attract major real estate investments, and enhanced connectivity is likely to further boost property values in the vicinity.

Market analysts suggest that the tunnel network could serve as a model for improved, sustainable, and commuter-friendly urban connectivity, potentially influencing future infrastructure projects across other metro cities in India. The ongoing infrastructure upgrades in Mumbai are already reshaping the real estate landscape across multiple corridors.

Next Steps and Timeline

Officials have reportedly indicated that a detailed design and project management consultancy would be appointed soon to finalise alignment, construction methodology, and execution timeline. If project approvals proceed as planned, the tunnel network could become operational in line with future phases of Metro 3 expansion.

The initiative is part of broader efforts to improve Mumbai's first underground metro infrastructure and create world-class transit facilities that integrate multiple modes of transportation seamlessly.
