What to expect

Work is underway on US 101 near Ruby Beach. Temporary traffic lights, a reduced 25 mph speed limit and single-lane alternating traffic are in place around the clock. 

Starting Monday, June 8, travelers will see occasional daytime alternating traffic at the site near Mansfield Road in Clallam County. 

Crews expect to complete work at both locations in late fall.

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

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.
