Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai is gearing up for a major overhaul, with plans to demolish and rebuild Terminal 1. However, the process will only commence once the second terminal at the upcoming Navi Mumbai International Airport (NMIA) becomes operational.

Currently catering to over 10 million domestic passengers annually, Terminal 1 will remain partially functional to avoid congestion at CSMIA. Officials from Adani Airport Holdings Ltd, which manages the airport, confirmed that portions of Terminal 1 have already been scaled down due to structural and safety concerns. “Complete demolition will only begin after Navi Mumbai’s Terminal 2 is active,” said Arun Bansal, CEO of the company.

The NMIA is under phased construction. Its first phase will support 20 million passengers annually, with the second phase boosting capacity to 50 million. The full closure and redevelopment of Terminal 1 at CSMIA will occur only after Phase 2 is completed.

Plans include reconstructing Terminal 1 on its existing footprint. However, authorities caution that the redevelopment will involve extensive construction, regulatory approvals, and system installations, potentially stretching over several years post-demolition.
