Truck carrying hazardous materials overturns

Traffic was being rerouted around 6 p.m. Sunday at the 172 milemarker near the location of the accident but was backed up 10 miles at one point while authorities closed off the area to investigate, according to Tennessee Highway Patrol officials.

By about 8 p.m., THP stopped rerouting traffic and opened lanes once more.

“As far as we can tell, there hasn’t been any release of any hazardous material into the environment,” said Kurt Pickering, spokesman for the Tennessee Emergency Management Agency.

THP officials are still trying to determine how the accident, which involved the truck and two other vehicles, occurred but believe the tractor trailer was carrying a flammable material.

Three people were transported to various hospitals, but authorities said none suffered life-threatening injuries.
