Mumbai Metro Rail Corporation has drawn up a proposal for a 3 km network of underground pedestrian tunnels to improve connectivity at the Science Centre (Worli) and BKC stations of Metro Line 3. The plan includes a 1.4 km tunnel linking BKC station with the upcoming bullet train terminal, and two tunnels at Worli measuring 1.1 km and 500 m. Each tunnel will be around 5 metres wide and will include escalators and elevators. The INR 250 crore project will be funded by MMRC and BMC, supported by TOD incentives, and is targeted for completion by 2029-30.
The Mumbai Metro Rail Corporation (MMRC) has proposed developing a 3 km network of underground pedestrian tunnels to strengthen access to two key stations on Metro Line 3 - the Science Centre station in Worli and the station at Bandra Kurla Complex (BKC). This network is planned to ease movement between these stations and nearby high-footfall destinations, reducing dependence on surface travel and offering uninterrupted walking access in all seasons.
At BKC, the plan includes a 1.4 km tunnel connecting the Metro 3 station with the upcoming Mumbai-Ahmedabad bullet train terminal. The proposal also outlines two tunnels for the Science Centre station, including a 1.1 km link leading towards the Worli Promenade via the Mahalaxmi Racecourse, and a 500 m tunnel connecting to the Nehru Planetarium.
The tunnels are designed with a width of about 5 metres and will include escalators and elevators at access points for easier movement. The estimated project cost is around INR 250 crore, and the funding model will involve both MMRC and the Brihanmumbai Municipal Corporation. The plan also uses provisions under transit-oriented development (TOD) policies, allowing properties within 500 metres of Metro 3 stations to receive extra floor space index if they integrate direct vestibule access to these walkways.
A design and project-management consultant will be appointed soon to carry out detailed surveys, confirm alignments, prepare technical layouts and recommend suitable construction methods. The project is intended for completion by 2029-30, aligning with the timeline of Metro Line 3's gradual operational rollout.
Similar pedestrian linkages already exist in parts of the city, including those connecting the airport terminals, and Mumbai authorities have been expanding such infrastructure to improve last-mile connectivity across the transport network.
