SR 305/Sam Snyder Creek – Remove Fish Barrier - Completed May 2025

Correcting fish passage barriers is an important part of WSDOT's efforts to protect and restore fish runs negatively affected by outdated culverts under state highways.

In 2013, a federal court injunction required the state to significantly increase efforts in removing state-owned culverts that block habitat for fish.

Replacing outdated culverts with new bridges and fish passable structures, which increase the likelihood of migration through the channel. Fish will be able to pass through easier as the water will be slower, and the bridges will replicate a more natural creek environment.
