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 sinkhole “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.”

Several passengers at the travel hub told The Post their flights made wonky detours to work around the runway closure, delaying their landings.

“We flew around Manhattan in a weird direction. Lately, with all the mishaps and near misses at major airports, I’m thankful they found it before a plane went into it. I hope there were no injuries,” said Kit Deason, an IT manager from Alabama who flew Southwest.

“The pilot said that there were delays because the planes were ‘single file lining up at LaGuardia’. They didn’t say a sinkhole. I’m a firefighter, so I know if they’re shutting down runways, there’s a problem,” added Ryan Mastian, who flew American Airlines from Indianapolis to meet up with Deason. 

The runway snafu also snarled some people’s travel plans, including those hoping to board connecting flights. 

“The pilot said over the loudspeaker that we may have to sit on the runway for a while when we landed, but we didn’t have to. But now our connecting flight is completely canceled,” said Samantha, a 36-year-old veterinarian from Maine.

Other jetsetters, such as Rick Samko, who was trying to fly back to Miami with JetBlue, complained about hours-long delays to board his flight.

“A sinkhole- that’s a first. A sinkhole at an airport — it wasn’t on my bingo card, I’ll tell you that. We were supposed to board at 8, and now the flights pushed back until 2 a.m. What’s going on?” said Samko, 42.

“Now I’m just trying to rent a car to drive home.”
