What to expect

Travelers will see single lane alternating traffic on temporary bypass roads to keep people moving around the work zones.

WSDOT and the contractor will make every effort to minimize the effects of road work on travelers and the community.

WSDOT will announce the work when it is scheduled via this webpage, email alerts, the Travel Center Map, and WSDOT app.

This project includes two fish passage sites. One site is located in Jefferson County near Ruby Beach and the other is in Clallam County south of Forks.

History and background

A fish passage barrier is anything that hinders fish from moving upstream or downstream. Culverts or pipes under the roadway allow water to flow but may not allow fish to swim through. Culverts may block fish migration because the water flow is too swift, too shallow, or has a waterfall into or out of the culvert.

Since 1991, WSDOT has worked to improve fish passage and foster healthy waterways. This is done by removing barriers that keep fish and other aquatic species from moving under the state highway.

Since 2013, WSDOT has worked to follow the requirements of a U.S. District Court injunction to correct barriers to salmon and steelhead.

These culverts part of a larger effort in Grays Harbor, Jefferson and Clallam Counties. The work will remove 29 barriers to fish under state highways.

A separate project at the Jefferson-Clallam county line began in March 2024 to replace a culvert under US 101 at May Creek.
