Needs & benefits

A culvert that runs under State Route 9 at milepost 34.7 south of Lake McMurray near the North Centennial Trail Trailhead is failing and needs to be replaced. The bottom of the culvert has rusted away, which means water is washing away the side of the road. This caused a sinkhole on the shoulder that was repaired in April 2018 and could cause further problems in the future. Contractor crews working for WSDOT need to close the highway for several days to dig up the old culvert and replace it during summer 2020.

People who use this section of the highway will need to plan for extensive detours in each direction during the closure. Crews will keep access to the North Centennial Trail Trailhead open from the north during this project.
