Streetsboro authorities are trying to determine what caused a fatal accident on State Rt 14 at the Lake Rockwell bridge in Portage County over the weekend.

Dennis Zavinski, 68, of Aurora was pronounced dead at the scene Saturday morning after crashing with a semi tractor trailer driven by Freddie Pampley, 54, of Cleveland. Pampley was treated at the scene and released.

State Route 14 between Price Road and Diagonal Road was closed for several hours as a result.
