Expect temporary traffic lights and around-the-clock alternating traffic at two locations south of Forks.
Project overview
This project will remove barriers to fish migration under US 101 at two locations in Jefferson and Clallam counties.
What to expect
Throughout summer 2025, travelers will see alternating traffic at two locations south of Forks. The work zones are located near Mansfield Road in Clallam County and between Ruby Beach and Kalaloch Beach in Jefferson County. Temporary traffic signals will be in place around the clock.
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.
