A six-hour closure of both the runways at the Mumbai Airport on account of repair and maintenance work has affected the operation of around 255 flights on Wednesday, officials said.
The primary runway and the secondary runway at the country's second busiest airport were shut down from 1100 hours till 1700 hours, they said.
The operations were normalised after 1700 hours, they said.
The Chhatrapati Shivaji International Airport handles around 1,000 flights a day on an average.
Mumbai International Airport Limited (MIAL), the joint venture company that runs the airport here, is undertaking maintenance and repair of the runways in two phases.
The Airports Authority of India (AAI) has 26 per cent stake in MIAL while GVK Group-led consortium holds majority 74 per cent.
The first phase was scheduled for this month and the next one will be carried out between February 7 and March 30 (except on March 21) from 1100 hours to 1700 hours on Tuesdays, Thursdays and Saturdays.
"At least 255 flights were affected at the Mumbai airport due to the six-hour long shut down of both the runways to carry out the repair and maintenance work," a senior official of AAI said.
