SR 4 - 0.5 miles East of County Line Park – Slope Stabilization

Project news

On July 25, 2018, a slope failure occurred on State Route 4, just east of the County Line Park near the Cowlitz and Wahkiakum counties, bringing debris, boulders and trees onto the roadway. It was determined that slope stabilization work needs to be performed on the slope, which will remove loose rocks and trees from the face of the bluff. This work will help prevent future landslides, road closures and provide a safer section of highway for travelers.  

Needs & Benefits

This work will help prevent future landslides and road closures and provide a safer section of highway for travelers. 

What can travelers expect?  

  • Monday, Oct. 15: Expect 20 minute closures on both directions of SR 4, from 6 a.m. to 6 p.m., for tree removal.
  • Friday, Oct. 19 through Tuesday, Oct. 23: Around-the-clock, alternating, single-lane closures with flaggers, and delays of up to 20 minutes on both directions of SR 4, from 12 p.m. Friday, Oct. 19 to 5 p.m. Tuesday, Oct. 23. 
  • Note: During construction, and especially during rock removal, lanes in both directions will be closed for up to 20 minutes at a time, to ensure the safety of the road users. 

Timeline
