US 101 - SR 109 Grays Harbor, Jefferson and Clallam Counties - Remove Fish Barriers

Project overview

This fish passage project includes 29 identified streams and culverts that cross under US 101 and State Route 109 in Grays Harbor, Jefferson and Clallam Counties in need of correction. Currently, these barriers do not allow fish to cross underneath the highways to access habitat.

WSDOT and the Design-Build contractor will consult with local stakeholders on potential detour routes and the length of highway closures for travelers. Once complete, this project will restore nearly 37 miles of potential habitat across the Olympic Peninsula.

What to expect

The culverts will be corrected by WSDOT's design build contractor as five separate bundles. One bundle containing 4-7 barriers will be corrected annually beginning in spring 2023 to meet the project's deadline of fall 2026. 

It's too soon to tell what the contractor may elect to do for traffic control measures. Travelers should expect anything from reduced speeds, shifted lanes, alternating conditions with flaggers or a temporary signal at varying sites while construction is underway. Any highway closures will be announced in advance. 

This project corrects 29 fish barriers under US 101 and SR 109 in Grays Harbor, Jefferson and Clallam Counties. Once complete, work will provide access to upstream habitat for salmon and other resident species.
