Sinkhole Shuts Runway at New York LaGuardia Airport

A sinkhole was discovered at New York’s LaGuardia Airport on Wednesday morning near Runway 4/22. m. The runway was immediately shut down, and emergency construction and engineering crews were dispatched to determine the cause and complete repairs.

The Port Authority said it is in close communication with airlines and airport partners and will continue providing updates as conditions evolve. Travelers were advised to expect delays and cancellations, particularly with forecast thunderstorms expected later in the day.

Passengers were urged to check directly with their airlines for the latest flight status information and to plan ahead by arriving early, parking in reserved spots, checking in, and clearing security with extra time.

Airport is built on land reclaimed from the surrounding bay in the 1930s. A 2025 report noted that airports face increasing challenges from uneven ground sinking along runways, with San Francisco International Airport reportedly sinking the fastest.

The runway closure comes nearly two months after an unrelated incident in which an Air Canada flight struck a Port Authority fire truck on the same runway. Two pilots were killed in that crash. m. Eastern time, the FAA’s airport monitoring service reported that a traffic management program was in effect for arriving air traffic due to expected thunderstorms, causing some arriving flights to be delayed an average of one hour and 37 minutes.
