One man is dead after a tractor-trailer rolled over on Interstate 80 in Mercer County Friday morning.
Pennsylvania State Police said 53-year-old Wayne Grahl was pronounced dead at the scene. They said he was not wearing his seat belt.
It happened around 11:30 a.m. along the westbound lanes of I-80 in Shenango Township, just about a mile from the state line.
Grahl lost control of his rig and it rolled off of the highway, hit a ditch and flipped over, investigators said.
No other vehicles were involved.
PSP said Grahl is from out-of-state but did not say exactly where he is from.
They do not know the cause of the accident and are still investigating.
