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

Project overview

This project will correct 29 identified streams and culverts that cross under US 101 and State Route 109 in Grays Harbor, Jefferson and Clallam Counties. Currently, the culverts under the highways do not allow fish to access vital 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 in 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. 

Travelers can expect to see reduced speed limits, shifted lanes, one-way alternating traffic and detours during construction. 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.
