State Police in Mercer County are investigating after a tractor-trailer overturned along a ramp at Interstates 80 and 79.

The truck flipped over onto its side in Findley Township at around 4:30 a.m. Friday as it was traveling from Interstate 80 westbound to Interstate 79 southbound.

A rescue squad was called, but the driver was able to get out of the cab on his own.

The truck landed off the ramp, so troopers say traffic is still moving in the area.
