Mumbai’s long-awaited airport-to-airport Metro connection is finally taking shape. The proposed Metro Line 8, or Gold Line, will offer a direct link between Chhatrapati Shivaji Maharaj International Airport (CSMIA) and the Navi Mumbai International Airport (NMIA), which opens on December 25. The need for a mass rapid link has now become urgent, with road travel between the two hubs currently taking 70 to 120 minutes, often longer during peak congestion.
A ₹23,000-crore corridor designed for speed
Maharashtra Government has approved the broad framework for the project. The 34.89-km corridor is expected to cost around ₹23,000 crore and will be delivered via a public–private partnership model. City and Industrial Development Corporation (CIDCO) Maharashtra will lead construction with support from a private consortium, following the build-operate-transfer structure used for Mumbai Metro Line 1.
As per reports, CIDCO’s Detailed Project Report has already received clearances from the Urban Development and Finance departments, with 20% viability gap funding proposed from both the Centre and the State.
