Flight operations at the Mumbai Airport—the second busiest in India—will remain shut for five hours today for its scheduled expansion.

The main runway will remain closed from 11.30 am to 4.30 pm for setting up Rapid Exit Taxiway Lights to enhance runway efficiency.

A Mumbai International Airport statement said that the closure was in consultation with aviation regulator Directorate General of Civil Aviation (DGCA), Airport Authority of India and airlines and there would be no inconvenience to the passengers.

The shut down period coincides with usually lean hours for the airport. Similar closure is also scheduled for March 3 and March 10.
