SR 9 - Unnamed Tributary to Pilchuck Creek - Fish Passage - Project map

A map showing the location of a culvert under SR 9 that will be replaced.

In summer 2020 WSDOT will replace a culvert that is failing underneath SR 9 in north Snohomish County near the North Centennial Trail Trailhead. The project will require a five-day closure of SR 9, including vehicles, bicycles and pedestrians. A signed detour will be in place.
