New Orleans Armstrong International Airport is temporarily closing its north-south runway, which means all takeoffs and landings will have to run either east or west.
"The north-south runway (Runway 2/20) will close for approximately 12 days to allow contractors to conduct necessary safety maintenance work," the airport announced.
The closure of runway 2/20 began Wednesday.
With 2/20 out of commission until the work is done, all aircraft will take off and land on runway 11/29.
Takeoffs from runway 11 and landings on runway 29 will take planes over Kenner immediately east of the airport.
"Due to this temporary runway closure, certain parts of Kenner and the surrounding areas may experience an increase in aircraft noise. If the work is completed earlier than the announced schedule, normal aircraft arrival and departure patterns on both runways will resume," the airport said.
The temporary closure of runway 2/20 should not impact airline operations or schedules.
