A fiery crash involving an 18-wheeler shut down a section of Interstate 35E in Lewisville Saturday evening.
It happened at about 7:30 p.m. in the 2400 block of northbound I-35E near Round Grove Road, a Lewisville police spokesman said. A tractor-trailer collided with a passenger vehicle, causing the trailer to break away from the truck.
One of the trailer's axles broke off and struck an overhead highway sign, the spokesman said. Texas Department of Transportation crews are expected to inspect the sign and determine whether it needed to be taken down.
