SR 401 - 2.3 Miles S. of Bean Creek Bridge - Slope Stabilization

Project overview

Due to roadway settlement from heavy rainfall, both directions of State Route 401 (also known as the Lewis and Clark Trail Highway) between the Astoria-Megler Bridge and Naselle are closed. The soil beneath the road near milepost 4.5 is too unstable to allow vehicles safely through and the entire stretch of highway was closed on Tuesday, February 23. This project aims to determine a long-term solution to stabilize and reopen the highway.

What to expect

Our geotechnical engineers are gathering extensive information in the field to help determine a long-term fix to stabilize and reopen the highway. However, because of the substantial damage caused to the roadway, long-term repairs will likely take months to complete and there is currently no estimated time for reopening the highway.

During construction of the bypass road, travelers should continue to use an alternate route and expect delays on US 101 about a mile west of the Astoria-Megler Bridge while crews work to repair a culvert under the highway. The Dismal Nitch Rest Area east of the Astoria-Megler Bridge remains closed

WSDOT is in contact with emergency service providers to ensure continued services while the highway is closed.
