Mumbai Plans 3 km Underground Pedestrian Tunnel Network to Strengthen Metro Line 3 Connectivity

Mumbai's urban transport infrastructure is reportedly set for a significant enhancement, with authorities planning to construct a 3-kilometre network of underground pedestrian tunnels connecting key stations along Mumbai Metro Line 3. The ambitious project aims to improve last-mile connectivity and streamline commuter movement, particularly around the Bandra-Kurla Complex (BKC) station and Science Centre station in Worli.

Key Features of the Proposed Tunnel Network

According to reports, the underground tunnel grid will feature a 1.4 km corridor linking the BKC station with the upcoming bullet train terminal, creating a seamless interchange between metro and high-speed rail services. This integration is expected to significantly enhance connectivity for commuters travelling across the BKC-Worli section of Metro Line 3.

In Worli, authorities have proposed two separate tunnels measuring 1.1 km and 500 metres respectively. These corridors are expected to improve pedestrian access to surrounding commercial and residential areas, complementing the existing Sewri-Worli connectivity projects already underway.

Each tunnel will reportedly be 5 metres wide and equipped with escalators and elevators to ensure accessibility for all categories of commuters, including senior citizens and differently-abled individuals.

Transit-Oriented Development at the Core

The project is understood to be part of a broader push for transit-oriented development (TOD) in Mumbai, similar to transit-oriented planning models being implemented in other Indian cities. Authorities believe the underground network will ease surface-level congestion and reduce traffic bottlenecks around key transit hubs.

The initiative aligns with Mumbai's ongoing infrastructure upgrades aimed at transforming the city's urban mobility landscape. The MMRDA has been actively working on multiple connectivity projects, including infrastructure development initiatives in BKC.

Expected Benefits for Commuters

Once operational, the underground tunnel network is expected to deliver multiple advantages for metro users:

• Reduced walking time between different transport modes and commercial destinations
• All-weather sheltered access eliminating exposure to monsoon rains and summer heat
• Improved integration between metro services, rail networks, and bus connectivity
• Decreased reliance on feeder services or private vehicles for last-mile movement

Transport experts suggest that better connectivity could encourage more commuters to choose public transport over personal vehicles, supporting sustainable urban mobility initiatives across the Mumbai Metropolitan Region.

Real Estate Implications

Industry observers note that such infrastructure developments typically have positive implications for real estate values in surrounding areas. The Mumbai Metro Line 3 corridor has already witnessed increased investor interest, and the proposed tunnel network could further strengthen property demand in BKC and Worli.

The BKC area continues to attract major commercial investments, with recent developments including large-scale office projects in the BKC vicinity. Meanwhile, Worli remains one of Mumbai's premier luxury residential destinations, with high-value property transactions continuing to attract attention.

Next Steps and Timeline

Transport authorities are reportedly working on finalizing design specifications, alignment details, and construction plans for the tunnel network. With necessary approvals and clearances in place, construction is expected to commence soon, and the network could become operational within the coming years.

The project adds to Mumbai's expanding metro network, which includes the city's first underground metro phase and various connectivity improvements designed to transform how residents navigate key transit zones.
