The driver of the big rig was merging onto 121 when he was clipped by a North Texas Tollway Authority dump trunk, caught fire and then hit a pickup truck. No serious injuries were reported in the crash, but it snarled traffic for miles after authorities closed the northbound lanes of Highway 121 and the ramps from northbound I-35E.

PERSONAL NOTE: I was driving north on State Highway 121 after returning from a doctor's appointment in Frisco TX when I saw a large black cloud of smoke appear ahead. The traffic almost immediately came to a halt and several emergency vehicles passed on the shoulders. I was able to take an exit and only lost about ten minutes time.
