Interstate 75 South - Farragut to Cleveland

Interstate 75

Dynamic message signs posted south along Interstate 75 from Exit 42 are part of a fog advisory area. Utilizing Intelligent Transportation System (ITS), these safety features were installed after a catastrophic car pile up on December 11, 1990. Occurring at 9:10 AM, the event involved 99 vehicles, claimed 12 lives and caused 42 injuries near the town of Calhoun (Exit 36). Due to the proximity to the Appalachian Mountains to the east, dense fog developing within the region of southeastern Tennessee can reduce visibility to zero miles.
