WALLULA -- A rock that fell on Highway 730 along the Columbia River south of the Tri-Cities caused an accident that damaged two semi-trucks.
The Washington State Patrol says a truck driven by Edward Klein, 63, of Kennewick, hit the large rock in the roadway around 7:30 Sunday night near Wallula.
The truck was forced into the shoulder and hit a barrier where a trailer axle tore loose and landed back on the highway. The second truck, driven by Darrel W. England, of Stevenson, hit the axle.
The patrol says the driver of the first truck suffered minor injuries. The driver of the second truck was not hurt.
