The Kennewick roundabout south of the blue bridge was partially blocked for three hours on Thursday after a semi-truck flipped on a curve.
The truck hauling 35,000 pounds of cardboard was heading west on Columbia Drive at 10:30 a.m. when it entered the roundabout to head south on Highway 395, said Trooper Chris Thorson with the Washington State Patrol.
The driver turned too fast and the truck rolled onto its side in the roundabout that connects Highway 240, Highway 395 and Columbia Drive. The state Department of Transportation said the road was cleared by 1:30 p.m.
No one was hurt.
