Updated at 11:09 p.m. with new information about the highway being open again.
The southbound lanes of Dallas North Tollway at the interchange with Interstate 635, have been opened back up as of 8:48 p.m., tollway officials said.
The lanes were initially closed due to an 18-wheeler that jack-knifed and crashed into the highway wall before catching fire, officials with Dallas Fire-Rescue said. The crash happened shortly before noon Sunday.
DFR officials said the HazMat team was sent out to the scene to handle the truck's diesel tanks. The fuel tank ruptured during the crash, which caused the fire, officials with the Texas Highway Patrol said.
While the fire consumed the entire cab of the truck, the driver and two passengers who were inside were able to make it out safely, fire officials said.
Neither person had any burns or life-threatening injuries, but both were taken to a local hospital as a precaution, according to officials.
