A crash on Interstate 75 has caused major delays for northbound drivers.
The multi-car crash happened shortly before 11 a.m. near mile marker 136 in Campbell County. The county dispatch center said three cars were involved, but no one was injured.
TDOT's automated system initially estimated that crash would be clear by 2 p.m. But traffic is still backed up for miles, stretching into Knox County according to the Anderson County Sheriff's Department. TDOT has now adjusted the estimated clear time to 4 p.m.
Southbound traffic is not affected.
The area has seen multiple crashes in the past few weeks. Because of construction underway, there is limited space to move the cars, creating backups.
