A rain-soaked hillside north of Woodland gave way Thursday afternoon, sending a mudslide across northbound Interstate 5 that blocked freeway traffic for five hours before road crews cleared two lanes at about 9 p.m.

The slide occurred around 3:50 p.m., according to the Washington State Department of Transportation, near milepost 22.6, close to Dike Road north of Woodland.

The slurry of mud cascaded across the highway, sweeping up a pickup in the process. No injuries were reported.

WSDOT spokesman Bart Treece said crews planned on lining the slide with concrete barriers and setting up cones in the other lanes to allow two lanes of traffic through.

Geotechnical engineers would then come Friday morning to assess the state of the hillside.
