Mumbai’s commute just got a turbo upgrade. The second phase of Metro Line 3—stretching from Bandra Kurla Complex (BKC) to Acharya Atre Chowk in Worli—was inaugurated on 9 May 2025 by Maharashtra Chief Minister Devendra Fadnavis, marking a key milestone in the city’s underground transit expansion.
Public operations for this stretch, part of the Aqua Line, will begin on 10 May. Officials say commuters will now be able to cover the BKC-Worli route in just 15 minutes—a sharp contrast to the 45-minute road journeys during rush hours.
The newly inaugurated Phase 2A includes three underground stations: BKC, Vidyanagari, and Acharya Atre Chowk. Spanning 5.75 kilometres, the corridor is designed to offer a direct and swift connection between South-Central Mumbai and its growing commercial hubs.
This section is part of the ambitious 33.5-kilometre Metro Line 3 project, which aims to connect Cuffe Parade in South Mumbai with Aarey Colony in the north through 27 underground stations. The line will intersect with multiple metro corridors and suburban rail networks, making it one of Mumbai’s most integrated transport projects.
According to the Mumbai Metro Rail Corporation Limited (MMRCL), the Aqua Line is expected to reduce over 6.5 lakh vehicle trips every year, easing congestion on the Western Express Highway and the Bandra-Worli Sea Link. The fully underground line also promises significant environmental benefits, including a projected annual reduction of 2.61 lakh tonnes in carbon emissions.
The new metro system brings several technological advancements to Mumbai’s public transport. Trains will be fully automated and driverless, equipped with advanced signalling, safety, and surveillance systems. MMRCL says that the carriages are designed for passenger comfort with air-conditioning, real-time travel updates, and priority zones for differently-abled travellers.
Phase 2A is the second stretch of the Metro Line 3 to become operational. The first section—from Aarey to BKC—was launched earlier this year. The remaining stretches, including the final southern extension to Cuffe Parade, are expected to open in phases through 2026.
Commuters and urban mobility experts have largely welcomed the launch. While many hailed the reduced travel times and underground comfort, concerns have been raised over limited last-mile connectivity around some stations. The MMRCL has acknowledged the feedback and assured improvements.
For now, Mumbai is celebrating what could be a game-changer for its famously congested roads and packed suburban trains. As the Aqua Line’s reach grows, the dream of fast, efficient, and sustainable transport seems closer than ever.
