TWO POSSIBLE SINKHOLES REPORTED IN DENVER MONDAY, INCLUDING ONE AT DENVER INTERNATIONAL AIRPORT October 26, 2026 Denver emergency communications have reported two possible sinkholes today, just over two hours apart, at separate locations across the city. 3:10 PM — DENVER INTERNATIONAL AIRPORT A possible large sinkhole was reported in the landside employee parking lot near Valley Head Street and Employee Lot Road at Denver International Airport. According to Denver Public Works dispatch communications, personnel were requested to inspect the area and place traffic cones if the reported condition presented a hazard. The report was categorized as a road closure incident, although the available dispatch information does not establish whether any roadway or parking lot access was actually closed. The size, depth, and cause of the suspected sinkhole have not been confirmed. 1:03 PM — IVANHOE STREET, CENTRAL DENVER Earlier Monday, a possible sinkhole was reported on Ivanhoe Street between East 11th Avenue and East 12th Avenue. The incident was associated with a reported road closure. The extent of the suspected pavement failure, any resulting damage, and the current status of the roadway have not been independently confirmed. TWO REPORTS, TWO DIFFERENT LOCATIONS The incidents were reported approximately two hours and seven minutes apart. There is currently no verified information suggesting the two incidents are connected. Sinkholes and roadway depressions can result from several conditions, including underground water leaks, soil erosion, drainage failures, and deterioration beneath pavement. The causes of these particular reports remain unknown. We will continue monitoring for additional information regarding inspections, road closures, and any potential public safety concerns.
