If things work as planned, Mumbai will have at least two-operational metro-lines in 2020 connecting the western-suburbs of the city. The two-corridors, Metro Line-2A and Metro Line-7, are proposed to be commissioned simultaneously in 2020, the MMRDA said in a statement. MMRDA has not yet received possession of land for a car-depot for Metro Line-7 as the land parcel is currently with the AAI.
