The truck, loaded with cardboard, was headed west.

Around 10:30am the semi was westbound when it tipped over in the roundabout that joins Highway 395, Highway 240 and Columbia Drive in Kennewick.

The driver was reportedly not injured, the State Patrol remains at the scene, and as of 1pm Thursday, the truck was still on it's side at the location. The investigation continues.
