From 7 to 11 p.m. on Sunday, Aug. 23, and from 8 to 11:59 p.m. on Friday, Aug. 28, contractor crews will alternate traffic on State Route 203 between Northeast 143rd Place and Northeast Big Rock Road in Duvall in support of an adaptive management project.
Contractor crews working for the Washington State Department of Transportation will add sandbars, adjust stream bed material, move logs and install water-resistant elements, such as shale, clay and silt, at Thayer Creek.
The project will enhance fish habitats and improve fish passage at four previously corrected fish barrier sites as part of WSDOT’s fish passage program. WSDOT has worked for nearly three decades to improve fish passage and reconnect streams to help keep waterways healthy. A 2013 federal injunction also directed WSDOT to significantly speed up efforts to remove barriers to fish migration.
Real-time traffic information is available on the WSDOT mobile app and the real-time travel map.
