The Mumbai Metropolitan Region Development Authority (MMRDA) has proposed a significant revision to the Mumbai Metro 13 project, which now features an 88% cost increase, bringing the total estimate to ₹17,724.99 crore. Originally planned to stretch from Shivaji Chowk (Kashimira) to Virar, the new route will run from Bhayandar to Dongarpada. This change aims to improve ridership and financial feasibility while also reducing the burden on the suburban railway system. The project will now include 17 stations along a 24.9-km route, with 3.25 km designated as underground, a shift from the initial plan of an entirely elevated line. Key stations will include Subhash Chandra Bose Ground in Bhayandar and Dongarpada in Virar, with a proposed car depot near Naringi Cricket Ground. The MMRDA highlighted that the cost escalation is due to inflation and the higher expenses associated with constructing underground metro lines compared to elevated ones. This project is expected to significantly enhance commuting for residents in the western Mumbai Metropolitan Region.
