LaGuardia sinkhole closes runway

The Port Authority of New York and New Jersey closed Runway 4/22 at LaGuardia Airport on Wednesday, May 20, after crews found a sinkhole during a daily inspection of the airfield around 11 a.m. local time. The closure hit one of LaGuardia’s two runways just as Memorial Day travel was building, forcing the airport to operate with reduced capacity. The Federal Aviation Administration then slowed arriving traffic, and airlines began canceling and delaying flights as thunderstorms also moved through the New York area. Port Authority crews were sent to assess the damage and begin repairs, according to airport and local news statements. ### Where was the sinkhole, exactly? Runway 4/22 was the affected strip, with officials saying the hole was found on the edge of the runway near a taxiway during the inspection. The Port Authority said the runway was shut immediately after the discovery and emergency construction and engineering crews were dispatched to the site. Local television reports on May 21 said the runway remained closed into Thursday morning while repairs continued. (abcnews.com) LaGuardia has two runways, so closing 4/22 reduced the airport’s operating flexibility at a time of heavy traffic. Port Authority contract and environmental documents show Runway 4/22 is a major piece of the airport’s airfield system and has been the subject of rehabilitation work in recent years. (cbsnews.com) ### Why did one runway closure ripple so widely? The FAA said it was slowing flights into LaGuardia “due to weather and a sinkhole on Runway 4/22.” That meant the runway problem was not the only constraint: thunderstorms were also limiting how many flights could safely arrive and depart across the region. NBC New York and NY1 reported that a ground delay was issued after the sinkhole was found, with additional delays and a ground stop later tied to weather. (panynj.gov) Newark Liberty, John F. Kennedy and Philadelphia also faced FAA traffic restrictions on May 20 because of storms, according to contemporaneous reports. That left the New York airport system handling both weather disruption and a capacity loss at LaGuardia on the same day. ### How bad were the delays and cancellations? (abcnews.com) Flight disruptions mounted through Wednesday and into Thursday, though totals varied by hour and outlet. CNBC reported the sinkhole closure was expected to delay flights, while local stations showed cancellation boards filling up as airlines adjusted schedules. FAA airport-status pages on May 20 and May 21 showed LaGuardia under traffic-management programs for thunderstorms, with average arrival delays stretching into hours at points during the disruption. (ny1.com) Independent aviation and travel outlets reported hundreds of cancellations over the two-day period, but the official public-facing sources focused on operational status rather than a single final tally. The clearest official guidance to passengers was to expect delays and check directly with airlines and airport flight-status pages before leaving for the airport. (cnbc.com) ### What were officials telling travelers? LaGuardia and the Port Authority told passengers to expect delays after the runway closure. The FAA’s public status pages separately warned of traffic-management initiatives tied to thunderstorms, and those pages remained the main official source for real-time delay conditions on May 21. (aerotime.aero) Travelers were also dealing with incomplete information from airlines. NY1 reported some passengers said carriers described their cancellations as weather-related without mentioning the sinkhole, even though the FAA had cited both weather and the runway problem. ### What happens next for passengers? (bloomberg.com) May 21 flight-status pages for LaGuardia and the FAA were still showing delays, though the FAA listing emphasized thunderstorms as the active traffic-management cause by Thursday morning. Travelers headed into the Memorial Day weekend can track the next changes on LaGuardia’s official flight page and the FAA’s airport-status page for LGA, where runway-related and weather-related restrictions are updated as conditions change.
