The tractor-trailer was hauling about 4,200 gallons of highway paint to Montana, Bailey said.
The driver told Bailey a tire blew out before she noticed the back of her trailer was on fire.
The southbound lanes reopened by 8:30 p.m., though traffic squeezed through reduced lanes northbound into the evening.
The area evacuated was a business and industrial area, Bailey said.
A church and the Cleveland County Family YMCA were both evacuated, but people were cleared to return to those buildings within two hours, Bailey said.
