A tractor-tractor carrying hazardous materials caught on fire Wednesday afternoon on U.S. 220 south in Roanoke, causing major delays for drivers for much of the afternoon and evening.
A tractor-trailer hauling pesticides caught on fire shortly after 2 p.m. near Southern Hills Drive by Home Depot in Roanoke, said Dawn Eischen, external affairs director for Virginia Department of Emergency Management.
Hazmat crews had not determined by Wednesday evening what materials the tractor-trailer was carrying besides pesticides or whether the fire affected the pesticides, Eischen said. Crews planned to transfer the materials from the damaged truck to a second tractor-trailer to determine what was on board.
Eischen said a hazmat officer reported there were no hazardous readings on air monitors.
Eischen said crews had not yet been able to determine what caused the fire.
Roanoke Fire-EMS spokeswoman Tiffany Bradbury said the driver was not injured.
Both northbound lanes of the four-lane road remained shut down while crews cleared the debris and loaded materials onto a second tractor-trailer.
Traffic stretched back nearly 10 miles into Boones Mill in the afternoon.
