Prime Minister Narendra Modi inaugurated the final phase of Mumbai’s first fully underground Metro 3, making the 33.5 km Aqua Line operational. The line connects Aarey in North Mumbai to Colaba in South Mumbai, aiming to ease congestion on suburban trains and roads.

The final stretch, spanning 11.2 km from Acharya Atre Chowk in Worli to Cuffe Parade, provides connectivity to six major business centres, including Nariman Point, Cuffe Parade, Fort, Lower Parel, BKC, and SEEPZ/MIDC. According to Mumbai Metro Rail Corporation (MMRC), the stretch also links areas such as Kalbadevi, Girgaum, Worli, and both international and intra-state airports that were previously unconnected to the Mumbai railway network.
