A crash between a tractor-trailer and a car at mile marker 162 on eastbound Interstate 24 has traffic at a stop. The accident happened about 11:30 a.m. Eastern time and is expected to take about two hours to clear, according to the Tennessee Department of Transportation. No information is available on the people involved in the crash. A motorist whose vehicle was stopped at mile marker 152 said in a cell-phone call that four firetrucks, three rescue trucks and three Tennessee Highway Patrol cars had passed her position traveling east, but she couldn't see the wreck site.
