The runway, known as 4-22, has been shut down since inspectors discovered a sinkhole along its edge on Wednesday.The Port Authority of New York and New Jersey, which operates LaGuardia, had expected the airport to be back at full capacity by Friday morning, Kathryn Garcia, the agency’s executive director, said on Thursday. But the agency said it had decided to keep the runway closed on Friday “out of an abundance of caution.”The Port Authority said crews using ground-penetrating radar had found “possible areas of concern” on Thursday. After repairing those spots, engineering crews continued to survey the area on Friday, the agency said.The same runway was the site of a fatal collision two months ago that involved an inbound Air Canada Express jet and an airport fire truck. The jet’s two pilots were killed in the crash.By late morning Friday, more than 300 flights in and out of LaGuardia had been delayed, though just a small number had been canceled, according to statistics provided by FlightAware, a tracking service.The Port Authority said LaGuardia would remain open but urged travelers to check with their airlines for updates on the status of their flights. The agency said that it expected to reopen the runway at 6 a.m. Saturday.This is a developing story.
