State police are investigating a hit-and-run accident that injured a young girl Friday night on Interstate 80.

At 5:39 p.m. an unknown eastbound vehicle towing a blue trailer sideswiped a Toyota Sienna when it moved from the left lane to the right lane.

The Toyota crashed into the cement wall of the Emlenton bridge in Richland Township, Clarion County.

The Toyota was driven by Donna Barker of Ellwood City and had three passengers, all children. One of the passengers, a 9-year-old girl, was taken to Clarion Hospital by Emlenton Ambulance for a minor injury.

The other vehicle allegedly fled the scene.
