Sinkhole shuts LaGuardia runway, triggering widespread flight delays
A sinkhole opened on the taxiway edge of Runway 4/22 at LaGuardia, prompting an immediate shutdown of that runway. All takeoffs and landings are now using Runway 13/31, which is expected to cause widespread delays and cancellations, especially with thunderstorms forecast later today. Investigators are reviewing potential causes, including a nearby fuel line tunneling project.
