Map showing locations where fish barriers will be removed.
In December 2024 and early January 2025, travelers saw single lane alternating traffic and lane closures at each future work site. Contractor crews performed work, such as drilling for soil classification, to help complete the design.
A fish passage barrier is anything that prevents fish from moving upstream or downstream. Culverts or pipes under the roadway allow water to flow but may not allow fish to swim through.
Since 1991, WSDOT has worked to improve fish passage and foster healthy waterways.
Since 2013, WSDOT has worked to follow the requirements of a U.S. District Court injunction to correct barriers to salmon and steelhead.
