Indian authorities plan to close one of three runways at Delhi's Indira Gandhi International Airport for maintenance and repair works.
Runway 10/28 will be closed from 2 April onwards for resurfacing and other repair works, says the ministry of civil aviation.
It is expected to resume full operations by 28 September, adds the ministry.
Aircraft taking off and landing at the airport during the repair period will use runways 27 and 29.
"Due to [an] increase in traffic and heavier aircraft, the runway surface has [become] distressed... The Director General of Civil Aviation has carried out an inspection of the runway and has concluded that the runway is in need of major repair works," says the ministry.
"The runway work on runway 28 will be carried out in a phased manner so as to ensure minimum inconvenience for the taxiing aircraft."
Authorities last resurfaced the runway in 1999, says the ministry, adding that runways generally require resurfacing every seven to 10 years.
