Months after the first tender was cancelled, the Mumbai Metropolitan Region Development Authority (MMRDA), on 11 December, invited tenders for the construction of Metro Line 12 that will run from Kalyan to Taloja.

As per the contract, the Rs 1,877.88 crore project involves part-design and construction of an elevated viaduct and 19 stations, with a completion time of 30 months.

The 20-km-long fully elevated metro corridor between Kalyan and Taloja has 19 stations planned at Kalyan, APMC Kalyan, Ganesh Nagar, Pisavali Gaon, Golavali, Dombivali MIDC, Sagaon, Sonarpada, Manpada, , Hedutane, Kolegaon, Nilje Gaon, Vadavali, Bale, Waklan, Turbhe, Pisarve Depot, Pisarve, and Amandoot (Taloja).

As part of plan to create an inter-connected network, the Metro Line 12 will connect to Metro Line 5 at APMC Kalyan and Navi Mumbai Metro Line 01 in Taloja.

The 24.9-km-long Metro Line-5 is an elevated corridor which connects Thane to Kalyan via Bhiwandi and is being developed in two phases. Construction work for the first phase, covering a 11.9km route between Thane and Bhiwandi, is almost 80 per cent complete and is expected to be operational soon. Work on the 11.8-km-long second phase from Bhiwandi to Kalyan would start soon.

Incidentally, the MMRDA had cancelled the first tender for the Kalyan-Dombivali-Taloja Metro Line-12 as the previous alignment did not connect with the 11.1-km-long Navi Mumbai Metro Line 1.

The Navi Mumbai’s first metro line, connecting Belapur and Pendhar, was opened for commercial operations on 17 November.

Once completed, metro route 12 will directly connect the cities of Kalyan-Dombivali with Thane, Mumbai and Navi Mumbai. Total project cost of Metro 12 is Rs 5,494 crore and JICA (Japan International Cooperation Agency) is the funding agency for the project, which is expected to be completed by October 2025.
