As part of WSDOT’s fish passage program, we will build a 26-foot fish-passable structure under SR 527 just south of 164th Street Southeast in Mill Creek. The current 9-foot culvert causes water to flow too fast for fish to continue upstream. The new bridge span will open more than 8 miles of…

Corrosion from weather is damaging the Snohomish River Bridge and Steamboat Slough Bridge.

A culvert that runs under State Route 9 at milepost 34.7, south of Lake McMurray near the North Centennial Trail Trailhead, was failing and needed to be replaced. The bottom of the culvert had rusted away, which resulted in water washing away the side of the road. This caused a sinkhole on the…
