Needs & benefits

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passage barriers is an important part of the state's efforts to protect and restore fish runs negatively affected by outdated culverts under state highways.

A 2013 federal court injunction required WSDOT to significantly increase the state’s efforts in removing state-owned culverts that block habitat for salmon, bull trout, and steelhead.

Replacing outdated culverts with either bridges or fish passable structures will increase the likelihood of fish migration. The improvements will slow water and build the creek to help simulate a more natural creek environment.

Blackjack Creek
Blackjack Creek is routed through a series of pipes under portions of the SR 16/SE Sedgwick Road interchange and both directions of SR 16 itself. The barriers to fish are located under the SE Sedgwick Road on-ramp to westbound SR 16 and the eastbound SR 16 exit to SE Sedgwick Road. Narrow pipes constrict the stream and increase water flows which makes it in adequate for fish passage.

Salmonberry Creek
Salmonberry Creek flows under are portion of SE Sedgwick Road (SR 160) approximately 2.3 miles east of SR 16. The existing culvert is inadequate for fish passage due to a long and narrow pipe under the roadway. The narrow pipe constricts the stream and increases water flows which makes it in adequate for fish passage.
