A sinkhole found on a LaGuardia Airport runway Wednesday led to flight delays, as workers scrambled to make repairs, officials said.

The pit was discovered around 11 a.m. near Runway 4/22 as the Port Authority conducted its daily morning inspection of LaGuardia’s airfield, the agency said.

The runway was quickly shut down as emergency construction and engineering crews descended on the site to complete repairs and determine the cause of the sinkole “as quickly and safely as possible,” according to a spokesperson.

The Port Authority cautioned travelers to expect disruptions.

“The Port Authority is in close communication with airlines and airport partners and will continue providing updates as conditions evolve,” the rep said. “Travelers should expect delays and cancellations, particularly with forecast thunderstorms expected later today, and are strongly encouraged to check directly with their airlines for the latest flight status information.”
