Project overview
This project will remove a fish passage barrier along Evans Creek at State Route 202 just west of 236th Avenue Northeast near Sammamish. Contractor crews working for WSDOT will remove an existing 6-foot box culvert and fish ladder and replace it with a fish-passable structure. This new structure has the potential to open more than 5.25 miles of habitat for coho, steelhead, sea-run cutthroat and resident trout.
What to expect
On SR 202 at Evans Creek, contractor crews will build a temporary bypass, called a shoo fly bypass, for one lane of traffic in each direction on the side of SR 202 near the construction area. Travelers can expect four weekend closures of SR 202 at Evans Creek to build the bypass at the beginning of the project and remove it at the end of the project. During these closures, a detour will guide eastbound and westbound SR 202 travelers around the work zone using 236th Avenue Northeast, Northeast Union Hill Road, 208th Avenue Northeast and 204th Place Northeast. Closure dates have not been set.
This project will improve fish passage under SR 202 west of 236th Avenue Northeast near Sammamish.
The culvert under SR 202 at Evans Creek does not allow fish to pass. When finished, this new structure will open more than 5.25 miles of fish habitat. This Evans Creek project is part of our fish passage program. Replacing the existing culverts and rebuilding the stream channels expands healthy fish habitat; an important step in restoring fish runs and increasing populations. This benefits commercial seafood operations and recreational fishers and provides more food for a declining orca population. Additionally, replacing these fish barriers helps us meet our obligation to remove barriers under the 2013 U.S. District Court injunction.
