Sinkholes Close Major Roads, Disrupt Traffic in Knoxville, Glenhardie

A sinkhole caused the indefinite closure of Airport Loop Road at McGhee Tyson Airport, a major traffic artery around the terminal and parking garages, prompting rerouting and travel advisories urging passengers to arrive three hours early. Officials quickly implemented detours for travelers from Knoxville and Blount County, directing them to use alternative routes such as Pellissippi Parkway and the free Phone and Wait Lot as a designated passenger pickup area to reduce congestion. Despite initial concerns about the closure's duration, swift repair efforts allowed the road to reopen late Thursday night, restoring access to the terminal and parking areas. Airport authorities communicated updates and detour instructions through their X account and local news outlets. The sinkhole's cause remains under investigation, with ongoing assessments to prevent future incidents. This situation highlights the importance of timely infrastructure repairs and clear communication during unexpected disruptions at busy transportation hubs.
