The Zanesville Post of the State Highway Patrol is investigating a semi tractor trailer accident on I-70 eastbound between Norwich and New Concord. A dispatcher for the Highway Patrol says both lanes of I-70 were closed as a result of the semi rolling over and blocking both lanes. There was also another vehicle involved in the accident. Reports from the scene indicate the driver of the semi was trapped in his truck and crews had to rescue him. The Patrol says the driver's injuries were not thought to be life threatening. The Highway Patrol says the Ohio Department of Transportation says one lane of the highway has been reopened to traffic. The accident remains under investigaton.
