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…

This project will remove the fish barrier on State Route 202 just east of Fall City at Mud Creek. The project will also improve the safety and reliability of SR 202 by addressing the need for frequent emergency maintenance and channel dredging at the crossing due to sedimentation and flooding of…

In July 2024, WSDOT began replacing two culverts near the intersection of State Route 202 and Northeast 124th Street between Redmond and Woodinville with a single culvert. Two creeks in the area — an unnamed tributary of the Sammamish Creek and High School Creek — will be realigned to merge with…
