This project removed two barriers to fish and repaved a section of Mountain Highway East (SR 7).
This project is complete.
Correcting fish passage barriers is an important part of WSDOT's efforts to protect and restore fish runs.
Crews replaced two outdated culverts. Crews also built features that replicate a natural stream. The improvements support every life cycle of fish.
Fresh pavement removed cracks and wheel ruts where water can collect. This gives drivers an improved ride especially during heavy rain.
Repaving preserves the highway structure and reduces the potential for costly emergency repairs.

A fish passage barrier is anything that hinders fish from moving ups or downstream. Culverts allow water to flow. Culverts can block fish migration because the water flow is too swift, too shallow, or has a culvert waterfall.
