The Mumbai Metropolitan Region Development Authority (MMRDA) on Friday announced the extension of Metro Line 12 with a new corridor, Metro 12A, along the busy Kalyan–Shilphata Road.
The project, which has received administrative approval of Rs 8,414.53 crore, was announced by Maharashtra Deputy Chief Minister and Urban Development Minister Eknath Shinde.
The development is being viewed as a major boost to connectivity in the Kalyan Lok Sabha constituency, which is represented by MP Shrikant Shinde.
Metro 12A to run parallel to Shilphata Road
The extended corridor will connect Kalyan Phata to Taloja via Dahisar Mori, running parallel to the congested Kalyan-Shilphata Road. The 18.4-km revised corridor, of which 10.5 km is already under construction, will feature 12 elevated stations, including Manpada, Katai Naka, Desai Naka, Padle Gaon, Kalyan Phata, Gotheghar, Dahisar Mori, Rohinjan and Khutare Village.
Between Katai Naka and Kalyan Phata, track and station sharing has been proposed with Metro Line 14 (Kanjurmarg to Badlapur). The corridor will also integrate with the Nilje Depot and the proposed Thane Bullet Train Station.
The project is expected to significantly decongest vehicular traffic on Shilphata Road while providing the first metro connectivity to Kalwa, Diva and Mumbra regions.
Double-decker elevated corridor approved
In addition to the metro expansion, MMRDA has cleared a Rs 5,909.21 crore double-decker elevated corridor between Kalyan Phata (Shilphata Junction) and Rajnoli in Bhiwandi.
The 19.4-km four-lane structure will have two levels: the lower deck for road traffic and the upper deck for metro operations, enabling seamless travel from Shilphata to Bhiwandi.
The corridor will integrate with Metro Line 5 (Thane–Bhiwandi–Kalyan), Metro Line 12, the extended 12A corridor, and the proposed Metro Line 14. It will also include eight entry-exit ramps, two railway overbridges, and major bridges over Desai Creek and the Ulhas River.
Rs 4,897 crore allocation in MMRDA budget
Earlier, in the MMRDA Budget 2026–27, Rs 4,897.19 crore was allocated for projects in the Kalyan Lok Sabha constituency. MP Shrikant Shinde recently reviewed the progress of key infrastructure works, including Metro Line 12, Palava Flyover, the Third Patri Bridge, the Waldhuni elevated corridor, and the Kalyan Ring Road.
Officials have been directed to accelerate ongoing works to ensure timely completion and early public access.
The Metro 12A expansion is expected to transform east-west connectivity across Kalyan, Dombivli, Navi Mumbai and Bhiwandi, further strengthening regional mobility in the Mumbai Metropolitan Region.
