Eight cars collided on the west Camas Slough Bridge Thursday morning after an earlier construction hiccup on state Highway 14.
Workers were in the process of paving the bridge when a plant providing the hot-mix asphalt broke down around 4 a.m. Thursday, according to Abbi Russell, spokeswoman for the Washington State Department of Transportation.
The speed limit was reduced from 55 mph to 35 mph while motorists traveled a short distance over a fabric moisture barrier without the same traction as a normal road surface.
The unfinished road appeared to have been part of what caused the collision, said Trooper Stephen Robley, spokesman for the Washington State Patrol. During the collision, which occurred around 7:30 a.m., cars started sliding around on the roadway.
