The Maharashtra government has approved Metro Line 8, also called the Gold Line, to connect Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai with Navi Mumbai International Airport (NMIA). The 35-kilometre corridor, part of the Mumbai Metropolitan Region Development Authority’s (MMRDA) Metro Master Plan, aims to improve airport connectivity and streamline travel for passengers. The project will be developed using the Public-Private Partnership (PPP) model, despite its mixed track record in Mumbai metro projects. A Government Resolution issued on Monday confirmed the state’s decision, initially taken in May 2024. While MMRDA was originally tasked with overseeing Metro 8, the City and Industrial Development Corporation (CIDCO) has now been appointed as the nodal agency. CIDCO has been directed to prepare a detailed project report for the line, as reported by Hindustan Times. The new corridor is expected to provide seamless access between the two airports, especially critical as NMIA is likely to become operational by mid of 2025. Currently, NMIA is accessible via the Atal Setu, and connectivity will further improve with the completion of the Worli-Sewri connector. Challenges With PPP Model However, the decision to use the PPP model has raised concerns. Metro 1, which connects Ghatkopar and Versova, was built on a PPP basis between MMRDA and Reliance Infra over a decade ago. While the metro line itself has been successful, the financial arrangement remains problematic, prompting all further metro projects in Mumbai to adopt a contract-based approach without private participation. Details Of The Metro Line 8 Project Metro Line 8 will span 35 km, comprising 25.8 km of elevated track and 8.2 km of underground sections. The route will pass through key areas like Kurla and Mankhurd, linking Lokmanya Tilak Terminus and a proposed Interstate Bus Terminal at Mankhurd. It will include 20 stations and integrate with Metro 2B. Estimated to cost Rs 15,000 crore (as per 2023 data), Metro 8 will take approximately six years to complete, marking a remarkable step toward enhancing urban mobility in the Mumbai Metropolitan Region.
