U.S. Highway 63 just north of Buck Creek Road was closed for approximately an hour Thursday evening.

A pickup truck traveling southbound caught fire just after 6:30 p.m.

Investigators told KTVO News the driver of the truck was flagged down by another driver because the bed of his vehicle was on fire.

When the unnamed man pulled over, investigators told KTVO the fire spread to the cab.

There were no injuries.

Both lanes of the highway were reopened at 7:45 p.m.

The Kirksville Fire Department, Missouri State Highway Patrol, Adair County Sheriff's Office and the Adair County Ambulance District were all at the scene.
