Mumbai’s First Fully Underground Metro Line Is Now Open—Connecting South To North In Record Time

Mumbai’s Metro Line-3, popularly known as the Aqua Line, has become fully operational as of October 9, 2025, marking a significant milestone in the city’s public transport infrastructure. The entire 33.5-kilometre underground stretch between Cuffe Parade in South Mumbai and Aarey JVLR in the north is now open to commuters. The first trains departed from both terminal stations promptly at 5:55 AM on the day of launch, according to officials.During the inauguration, Prime Minister Narendra Modi lauded the project as a milestone in India’s development and praised the engineers for safely constructing the metro amidst Mumbai’s bustling cityscape and heritage structures. Seamless Travel Across Key DistrictsThe Mumbai Metro Rail Corporation (MMRC), which manages the project, had previously opened portions of the line. The final phase involved the completion of the last 10.99-kilometre section between Acharya Atre Chowk in Worli and Cuffe Parade, thereby completing Mumbai’s first fully underground metro corridor. This stretch boasts 27 stations and provides seamless connectivity across vital business districts, popular tourist locations, and densely populated residential areas.The Aqua Line is anticipated to dramatically alleviate Mumbai’s notorious road congestion, cut down commuting times, and offer a comfortable, reliable alternative for daily travellers. Earlier phases saw the launch of the 12.6-kilometre Aarey to BKC segment in October 2024 and the 9.7-kilometre BKC to Acharya Atre Chowk stretch in May 2025.With the entire corridor now operational, the Aqua Line—Mumbai’s very first fully underground metro line—promises to revolutionise urban mobility, enhancing access and convenience across the city’s sprawling metropolitan landscape.Transforming Urban Mobility In MumbaiThe Mumbai Metro Line-3 project was supported by the Japan International Cooperation Agency (JICA), which provided loans amounting to JPY 354,132 million towards the total cost of JPY 680,692 million.Connecting key locations such as SEEPZ, Bandra-Kurla Complex, Dharavi, Mumbai Airport, and Cuffe Parade, this metro line is set to transform daily commutes for hundreds of thousands of passengers, offering faster and more comfortable travel across the city.
