A sinkhole discovered Wednesday morning has shut down one of New York's LaGuardia Airport's runways, forcing emergency crews into a race against the clock to assess damage and restore operations before thunderstorms move into the region.
Airport officials spotted the cavity near runway 4/22 around 11am during a routine morning inspection. The runway was immediately closed, and construction and engineering teams mobilized to determine what caused the collapse and what repairs would be needed.
The Port Authority issued a travel alert warning passengers to expect significant disruptions. By 3pm, the FAA reported incoming flights were being delayed by an average of one hour and 37 minutes due to both the runway closure and deteriorating weather conditions moving toward the airport.
LaGuardia, which primarily handles domestic flights, sits on engineered land reclaimed from the surrounding bay during the 1930s. That terrain once housed residential neighborhoods, hotels, and an amusement park before being transformed into an aviation hub.
The incident highlights a growing infrastructure vulnerability facing major U.S. airports. According to a 2025 report, roughly 3.5 million square meters of runway across the country are experiencing significant subsidence. San Francisco International Airport has become a particular concern, sinking faster than any other major facility in the nation. Nearly 14,000 square meters of runway nationwide have been flagged as facing high risk of structural damage.
The closure comes less than two months after an unrelated Air Canada flight crashed on the same runway, striking a Port Authority fire truck and killing both pilots in the cockpit. That incident had raised questions about runway safety operations at the busy metropolitan airport.
Travelers were urged to contact their airlines directly for the most current information on flight status, given the compounding effects of the structural failure and severe weather expected to affect the region.
