According to multiple reports, a sinkhole discovered near Runway 4/22 at New York's LaGuardia Airport on Wednesday has caused significant travel disruptions. The runway was immediately closed after the sinkhole was spotted during a routine inspection around 11 a.m. EDT.

The Port Authority of New York and New Jersey is in close communication with airlines and airport partners, warning travelers to expect delays and cancellations, particularly with forecast thunderstorms expected later today. As reported by Reuters, about 200 flights were cancelled and 190 delayed as of Wednesday afternoon.

The sinkhole has left LaGuardia with only one operational runway, Runway 13/31, which is expected to lead to extensive cancellations and delays. Unlike nearby John F. Kennedy International Airport and Newark Liberty International Airport, which have multiple runways, LaGuardia has just two.

The upcoming Memorial Day weekend complicates the airport's schedule, with travelers urged to check their flight status before heading to the airport. The Port Authority sources are investigating various possibilities that may have caused the sinkhole, including a fuel line tunneling project.
