A sinkhole discovered during a routine inspection on Wednesday forced the closure of Runway 4/22 at LaGuardia Airport in Queens [1, 2, 3].
The shutdown of one of the airport's two primary runways significantly reduces operational capacity, leading to widespread travel disruptions for thousands of passengers. Because LaGuardia serves as a critical hub for the New York City metropolitan area, any reduction in runway availability creates immediate bottlenecks in air traffic.
Airport authorities identified the sinkhole during a routine morning inspection on Wednesday [2, 3]. The runway was shut down around 11 a.m. that day [2]. Following the closure, the airport experienced hundreds of flight cancellations and delays [4].
Maintenance crews have been working to repair the damaged pavement to ensure safety protocols are met before aircraft resume operations. The timeline for the runway's return to service has varied across reports. One estimate suggested the runway would remain closed until Thursday morning [5]. Other reports indicated a reopening was expected around noon on Thursday [2].
Additional projections suggested the runway would be operational before Friday flights began [6]. The disruption has forced airlines to reroute some traffic or delay departures while the remaining runway handles the increased volume of flights.
LaGuardia officials said they have not provided a detailed cause for the sinkhole's formation, but the discovery during a scheduled inspection prevented a potential aviation incident on the active strip [2, 3].
“The runway was shut down around 11 a.m. Wednesday”
The incident highlights the vulnerability of high-traffic urban airports where a single point of failure—such as one of only two runways—can paralyze regional air travel. The reliance on routine inspections to catch structural failures before they result in accidents underscores the critical nature of preventative maintenance in aviation safety.
