The Mumbai Metropolitan Region Development Authority (MMRDA) is set to extend Metro 4 from Kasarvadavali in Thane till Gaimukh.

Metro 4A corridor, to be developed at a cost of Rs 949 crore, will have two stations -- Gowniwadi and Gaimukh. The extension of 2.68 km will ensure that the entire Ghodbunder road is connected by the Metro corridor till Gaimukh.

With the Andheri east-Dahisar east Metro 7 corridor to be extended till Mira-Bhayandar, the MMRDA is considering the feasibility of extending it till Gaimukh.

The car depot for Metro 4 corridor is likely to be constructed in Gaimukh instead of the earlier proposed site at Owale.

The proposed 32 km Wadala-Ghatkopar-Thane-Kasarvadavali corridor will also be extended in the south till GPO, improving connectivity between south Mumbai and Thane.

Prime Minister Narendra Modi inaugurated the Metro 4 corridor in December 2016. However, the project worth Rs 14,549 crore is yet to start.
