The 3.4 kilometre extension of the Red Line Seven includes 2.5 kilometres underground and 0.94 kilometre elevated. It features two stations — Airport Colony (elevated) and Terminal Two (underground). Tunnel boring machine Disha completed a 1.647 kilometre downline tunnel from Terminal Two. The project used advanced engineering to overcome complex obstacles like utility lines, existing metro tunnels, and shallow soil cover.

Once operational, Line Seven A will offer smoother transfers to Lines One and Three and direct connectivity to Navi Mumbai International Airport via the future Line Eight. As of now, construction progress is at fifty-nine per cent, with launch targeted for December twenty twenty-six.
