This project eliminates barriers for fish and provides access to upstream habitat for approximately 29-identified streams or culverts that are out-of-date and needing correction. The end result will simulate what is found in a natural stream bed for salmon and resident fish.
WSDOT and the Design-Build contractor will consult with local stakeholders on potential detour routes and the length of highway closures for vehicles, bicyclists and pedestrians. Once complete, this project will restore nearly 37 miles of potential habitat across the Olympic Peninsula.
Why is WSDOT correcting fish passage barriers under US 101 and SR 109 between Aberdeen and Port Angeles?
Correcting fish passage barriers is an important part of the state's efforts to protect and restore fish runs negatively affected by outdated culverts under state highways.
In 2013, a federal court injunction required the state to significantly increase the state’s efforts in removing state-owned culverts that block habitat for salmon, bull trout and steelhead.
Replacing the outdated culverts with concrete box-culverts, steel-arched culverts or bridges increases the likelihood of migration through the channels. Fish will be able to pass through easier, as velocity or surface level barriers are reduced and promote healthy habitats for salmon and resident fish.
The following streams and/or culverts have been identified in collaboration with the Washington State Department of Fish and Wildlife for this project in need of correction (please note these culvert locations or preliminary and could change based on the scope of the project and need):

The End Result
The existing stream channels identified will simulate natural streambeds for improved fish migration. The work will potentially open up nearly 37 miles of upstream habitat for several fish species.
Due to the size and scope of this progressive Design-Build project, the work will occur over a five-year period. All in-stream work will occur during approved Department of Fish and Wildlife's "Fish Windows" to minimize impacts to aquatic species. Timelines are subject to change.
Funding for design, right-of-way, permitting and construction will be made available after the contract is awarded.
