A semitrailer loaded with more than 20 tons of baled cardboard tipped on its side Wednesday after pulling off northbound Interstate 5 and entering the Gee Creek Rest Area south of Ridgefield.
The incident happened at about 11:20 a.m. in the rest area, just after the access road splits into a route for trucks and another for passenger vehicles.
There was no effect on freeway traffic, Washington State Patrol Trooper Will Finn said.
The accident resulted in a sizeable oil spill, said Battalion Chief Tim Dawdy, with Clark County Fire & Rescue. CCF&R firefighters and crews from the Washington State Department of Transportation cleaned up the spill.
The truck was driven by Bret C. Wagner, 54, of Wood Village, Ore.
According to a Washington State Patrol news release, Wagner was driving too fast as he tried to negotiate the curving roadway.
