Mumbai Metro Aqua Line – Info, Route Map, Fares, Tenders & Updates
Mumbai Metro’s Line-3 (Aqua Line) is a 33.5 km under construction metro line with 27 stations connecting Cuffe Parade – BKC – Aarey Colony.
Mumbai Metro Rail Corporation Limited (MMRC) is the nodal agency responsible for building and operating this primarily-underground line, and was constituted as a JV of the Govt. of India (GOI) and the Government of Maharashtra (GOM) on a 50:50 sharing basis.
Line-3 was approved for construction by India’s central government on June 28, 2013 with an estimated cost of Rs. 23,136 crore. A majority of it (57.2%) is being financed through an official development assistance (ODA) loan of Rs. 13,235 crore from Japan International Cooperation Agency (JICA) with an interest rate of 1.15% for project activities, 0.01% interest rate for consulting services, and 30 years of repayment (including 10 years of grace period).
7 contracts for the construction of Line-3’s underground tunnels and stations were awarded in July 2016 (see contractor list at the bottom). Construction work began in January 2017 and the first of 17 tunnel boring machines (TBMs) began excavation in November 2017.
Line-3 will open in 2 stages (Aarey Colony – BKC and BKC – Cuffe Parade) and was originally targeted to open by June 2021, but will be delayed due to construction delays and protests by citizens (activists, Bollywood actors etc.) against the felling and transplanting of trees from Aarey Milk Colony where the line’s maintenance depot (car shed) is planned. As of 2021, construction elsewhere is ongoing but civil work has not been able to commence for the depot’s structures and the at-grade Aarey Colony Station.
Whenever the line opens, Line-3 will be connected to other metro lines, bus and suburban rail services through multiple interchanges throughout its north-south route. The line’s official colour as Aqua was revealed to the public on August 16, 2019 by the then incumbent chief minister.
