Expect around-the-clock single-lane alternating traffic with temporary signals on US 101 at the Jefferson-Clallam county line through fall 2026. The speed limit is reduced to 25 mph between mileposts 184 and 185.
Project overview
This fish barrier removal project replaces an outdated culvert under US 101 south of Forks. A 175-foot-long concrete girder bridge will replace the existing metal pipe to improve fish migration in May Creek.
What to expect
Since October 2024, travelers have seen one-way alternating traffic on US 101 near the Jefferson-Clallam county line. Temporary traffic signals will continue to alternate travelers through fall 2026.
In summer 2026, crews will work to rebuild the streambed under the highway.
US 101 at May Creek is currently 67% passable and in need for correction. Once complete, the work will increase potential habitat for salmon, coho, chinook and several other species.
US 101 at May Creek near Forks has been identified as a barrier to fish migration. This project will eliminate barriers for resident salmon and other fish species while increasing potential upstream habitat. The work in the channel will simulate what is found in a natural stream bed.
May Creek is a tributary to the Bogachiel River, which is a popular breeding zone for fish. Once complete, this project is expected to produce nearly 8 miles of potential habitat gain for salmon.
Why we correct fish passage barriers
State highways cross over rivers and streams in thousands of locations throughout Washington. Some crossings can impede fish migration. WSDOT is working to improve fish passage and foster healthy waterways by removing barriers that limit or prevent fish from feeding, migrating and reproducing.
Working to comply with the requirements of a 2013 U.S. District Court injunction, WSDOT corrects barriers to salmon and steelhead within the case area. The area is primarily located in western Washington.
As of June 1, 2026, WSDOT has corrected 200 injunction barrier culverts. This work has improved access to 705 miles of potential habitat for salmon and steelhead in the injunction area. Statewide, WSDOT has completed 483 fish passage barrier corrections since the 1990s when the Fish Passage Program was created.
