Mumbai Metro Line 3, heralded as a transformative addition to the city’s transport infrastructure, is nearing completion amidst a backdrop of escalating costs and strategic operational milestones. Known as the Colaba-Bandra-SEEPZ Line, this ambitious underground corridor spans 33.5 kilometres, featuring 27 stations from Cuffe Parade to Aarey Colony.
Managed by the Mumbai Metro Rail Corporation Limited (MMRC) through a joint initiative between the Government of India and the Government of Maharashtra, the project was originally estimated at INR 23,136 crore when approved in 2018. However, due to various challenges including land acquisition issues and pandemic-related disruptions, the projected costs have surged significantly.The Japan International Cooperation Agency (JICA) has been instrumental in financing a substantial portion of the project, initially providing INR 13,235 crore via Official Development Assistance (ODA). Recent updates indicate a revised project cost now standing at INR 37,275.50 crore, reflecting an increase of INR 14,139.50 crore over the original estimate.The rise in costs is attributed to several factors including additional expenditures on land acquisition, consultant fees, rehabilitation and resettlement efforts, architectural systems, and administrative expenses. These developments underscore the complexities and financial exigencies inherent in executing mega-infrastructure projects in urban landscapes like Mumbai.
Technologically advanced, Mumbai Metro Line 3 will boast Grade 4 automation, enabling driverless operations after an initial phase involving human supervision. Alstom Transport, in collaboration with its Indian subsidiary, has been pivotal in supplying 336 coaches equipped with the Urbalis 400 CBTC signalling system, capable of accommodating up to 3,000 passengers per train.While the project has faced delays pushing the anticipated completion date from September 2024 to December 2024, the MMRC remains committed to ensuring comprehensive readiness and operational efficiency. The revised timeline aligns with adjustments in financial planning and strategic commitments from the state government, which has increased its equity contribution to cover the escalated costs.As Mumbai prepares for the operational debut of Metro Line 3, stakeholders anticipate significant improvements in urban mobility and connectivity across key points in the city, integrating seamlessly with existing rail and road networks. The project stands as a testament to Mumbai’s ambitions in enhancing public transport infrastructure amid evolving socio-economic dynamics.
