If all goes as per plan, Mumbai may soon get to use the entire 33.5-km Metro-3 Aqua Line from Colaba to Seepz by Dussehra (October 2).
The phase one of the Mumbai Metro-3 line — Aarey Colony to Bandra-Kurla Complex (BKC) — was thrown open to public on October 7, 2024. The phase two from BKC to Worli was launched on May 9, 2025. The third phase from Worli to Cuffe Parade has been under-construction.
With the third phase of Mumbai Metro-3 operational, the travel from Colaba to Aarey Colony will be completed within one hour. Currently, it takes 120-180+ minutes to cover the stretch by road during peak traffic.
Is Worli to Cuffe Parade stretch of Mumbai Metro-3 ready?
The phase three of Mumbai Metro-3 has following stations — Science Museum, Mahalaxmi, Mumbai Central, Grant Road, Girgaon, Kalbadevi, CSMT,
Hutatma Chowk, Churchgate, Vidhan Bhavan, Cuffe Parade. Its cost is Rs 9,785 crore.

The Commissioner of Metro Railway Safety (CMRS) on Friday carried out a preliminary inspection of the final phase of the corridor, according to media reports.

Why Mumbai desperately needs the Metro-3?
Phase 1 of Mumbai Metro-3 alone has cut 650,000 car trips daily. Phase 2A has attracted over 32,000 passengers/day within two days of launch, connecting key business hubs (BKC, Worli, Dadar).
The full line predicted to serve up to 13 lakh passengers.
The Mumbai Metro-3 links major business zones: BKC, Worli, Dadar, plus airport access and SEEPZ tech park.
The line has made easy travel possible:
BKC to Worli: 13-15 minutes by Metro versus 45-60 minutes by road
Andheri to Cuffe Parade: 45-50 minutes by Metro versus 90-120 minutes by road
CSIA T2 to BKC: 10-12 minutes by Metro versus 30-45 minutes by taxi in traffic
Previously, to go from Andheri to Fort or Cuffe Parade, commuters had to take the Western Express Highway-Mahalaxmi-Peddar Road-Marine Drive or switch between autos, buses, trains, and taxis. So it would mean two-three different modes and 90 minutes.
