A sinkhole discovered during a routine morning inspection shuts down one of New York’s LaGuardia Airport runways, disrupting domestic air traffic. Multiple outlets report the sinkhole is found near Runway 4/22 at about 11:00 a.m. Wednesday, prompting airport and Port Authority officials to close the runway while emergency crews assess the damage and determine the cause and repair timeline. With one runway taken out of service, LaGuardia operates flights on its remaining runway, which leads to widespread delays and some cancellations. ABC News, Fox News, and other reports note travelers should expect disruption on Wednesday. By Wednesday afternoon, reporting indicates cancellation rates rise significantly, with flights affected during periods of thunderstorms while crews work toward reopening. Separate coverage also suggests officials expect the runway could reopen around midday Thursday, though the exact timing depends on repair progress and further assessment. The reporting is consistent that the closure begins immediately after the sinkhole is identified during the daily inspection.
