LaGuardia Airport reopens runway after finding depression weeks after sinkhole forced closure

LaGuardia Airport has reopened one of its runways after it was shut down for hours to conduct precautionary structural testing, the Port Authority of New York and New Jersey said.

In a statement, the Port Authority said a two-inch depression was found adjacent to Runway 4/22 during an airfield inspection Wednesday, and the runway was shut down at 5 p.m. so crews could conduct testing, identify the cause of the depression and perform stabilization work.

LaGuardia's other runway, Runway 13/31, remained open.

Port Authority said Runway 4/22 reopened at 6 a.m. Thursday and was fully operational.

LaGuardia's Runway 4/22 was shut down for two days in May when a sinkhole was spotted at the edge of the taxiway. The cause of that sinkhole remains under investigation. The closure in May caused numerous delays for travelers.
