A 57-year-old Langhorne man was killed Friday by a piece of flying road debris on the Pennsylvania turnpike, Pennsylvania State Police said.

Gregory Leiber was killed when a truck driving in the opposite lanes of the turnpike hit a piece of debris, sending it flying over the concrete barrier in the middle of the road and into Leiber's path.

He was struck in the head and pronounced dead at the scene, which was in Whitemarsh Township in Montgomery County.

State troopers are working to identify the truck that hit the debris.
