Mumbai Metro Lines 7A and 9 are vital components of the city’s expanding metro network, designed to enhance east-west and north-south connectivity in the western suburbs. Metro Line 7A is a 3.8 km underground extension of the operational Metro Line 7 (Dahisar East to Gundavali), connecting Andheri East to Chhatrapati Shivaji Maharaj International Airport (T2). This underground stretch will feature two stations and provide direct metro access to the airport, easing congestion on the Western Express Highway and offering crucial interchange points with Metro Lines 1, 2A, and 7.

Metro Line 9 extends the network northwards from Dahisar East to Mira-Bhayandar, covering approximately 11.4 km. This elevated corridor will significantly improve access for commuters from the northern suburbs, linking them with the rest of the metro grid and reducing road traffic in high-density zones.
