Commuters in Mumbai are set to benefit from a smoother journey as Metro 3 prepares to integrate seamlessly with the CSMT railway station subway. The connection is expected to make travel to South Mumbai, including key destinations like Cuffe Parade and Mantralaya, far more convenient.
The integration allows passengers arriving at CSMT on local trains to directly access the Metro 3 line without exiting the station, cutting down walking time and simplifying transfers. For daily commuters, this means a faster, hassle-free journey from the heart of the city to its southern business and administrative hubs.
The Metro-3 route will feature several stations, including Science Museum, Mahalaxmi, Mumbai Central, Grant Road, Girgaon, Kalbadevi, CSMT, Hutatma Chowk, Churchgate, Vidhan Bhavan, and Cuffe Parade. Previously opened was a 9.8-km segment from BKC to Worli with six stations: Dharavi, Shitaladevi Temple, Dadar, Siddhivinayak Temple, Worli, and Acharya Atre Chowk (Worli Naka).

The completion of this metro line marks a significant milestone in enhancing public transport infrastructure in Mumbai. It not only provides faster travel but also connects major business districts with residential areas seamlessly.
Which CSMT platform connects to the Metro 3 subway?
The subway connecting CSMT to Metro Line 3 begins from Platform 1, specifically at the Harbour Line exit. This allows commuters arriving on the Harbour Line to directly access the Metro 3 station without exiting the railway premises.
Will Hawkers Crowd the New CSMT–Metro 3 Subway?
Poople have welcomed the seamless CSMT–Metro 3 subway link but expressed concerns over potential hawker encroachments.
“Just hope these hawkers will not encroach the metro subway like they have encroached Churchgate and CSMT subway,” one commuter remarked.
One commuter joked sarcastically about managing hawkers, saying, “Providing big air-conditioned hawkers’ place.”
Others questioned why similar connectivity wasn’t prioritised at other busy stations: “Why didn’t they do this inter-connecting at Dadar station? Dadar metro is literally 400 meters from Dadar station but not connected. That street is full of hawkers,” a resident pointed out, highlighting the persistent challenge of informal vending in Mumbai’s transit hubs.
Is subway equipped with escalators and lifts?
The CSMT–Metro 3 subway is designed with lifts and escalators, not just ground-level access. These facilities are included to help commuters move easily between CSMT’s Platform 1 (Harbour Line exit) and the Metro 3 station.
Will Mumbai Metro-3 save time?
Once the Prime Minister inaugurates the 10.99-km section from Worli to Cuffe Parade, Mumbai commuters will be able to travel from Aarey to Colaba in just one hour, saving one to two hours compared to road travel. The Worli–Cuffe Parade stretch will take only 15 minutes, while BKC to Worli can be covered in 13–15 minutes. By road, the same journey currently takes 45–60 minutes.
