Delhi Metro Rail Corporation (DMRC) on Monday invited bids for topographical survey work to prepare a Detailed Project Report (DPR) for extending Mumbai Metro’s 24.9 km Line-5 (Orange Line) by 7 km from Durgadi Chowk in Kalyan to Ulhasnagar, with a new 8 km loop within Bhiwandi connecting Rajiv Chowk with Temghar.
This tender notice came out of nowhere. A metro line to Ulhasnagar was announced by the then Chief Minister Devendra Fadnavis back in October 2019 during his election campaign, but no formal plans for it have ever been announced.
The Mumbai Metropolitan Region Development Authority (MMRDA) in fact has existing plans in motion to extend the partly under construction Line-5 by 20.7 km from Kalyan APMC to Taloja in Navi Mumbai. They’re currently in the process of selecting a General Consultant (GC) for its civil works, with the last date to submit bids coming up on September 29.
With this new plan now in place, it appears the Orange Line in the future will bifurcate at Durgadi Chowk, with one branch continuing south-west to Kalyan APMC (and onward to Taloja as Line-12), and the other branch heading south-west to Ulhasnagar.
