Authorities have reopened a stretch of interstate 35 near Winston that was shut down for hours when two semis collided head on.

The Missouri State Highway Patrol says the accident happened shortly after 1am Friday just north of Cameron near the Winston exit.

Sergeant Sheldon Lyon says a northbound big rig crossed the median and rammed into another truck in the southbound lanes.

Both rigs caught fire.

Lyon says the driver of the northbound semi who was killed has not yet been positively identified. His passenger was taken to KU Medical Center for treatment.  Michael McQueen, 58, of Jonesboro, Tennessee is in serious condition.

The driver of the other truck was transported to the Cameron Regional Medical Center.  Raymond Emard, 57 of Racine, Wisconsin was treated and released.

Lyon says 600 gallons of diesel fuel spilled into the ditch.   That spill was cleaned up by hazardous materials crews from the Department of Natural Resources and the Region-H Haz Mat team.
