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…

As part of the state's fish recovery efforts, WSDOT has made it a priority to reconnect waterways where our roads act as barriers. In western Washington, that means building hundreds of fish passable structures under state highways in the next decade to create habitat gain essential for…

Contractor crews working for WSDOT will paint the southbound SR 529 Steamboat Slough Bridge between Marysville and Everett, which has deteriorated due to weathering. This project will replace the paint to preserve the existing structural integrity and extend the service life of the bridge.

Corrosion from weather is damaging the Snohomish River Bridge and Steamboat Slough Bridge. Beginning in 2023, crews working for WSDOT have been rehabilitating the northbound SR 529 Snohomish River Bridge between Everett and Marysville by repairing or replacing steel truss elements, substructure…

WSDOT built two compact roundabouts on SR 530 at the intersections of 59th Avenue Northeast and 211th Place Northeast, just west of Arlington. These compact roundabouts reduce the risk of serious collisions at these intersections as drivers will no longer have to make turns across lanes of fast-…

This project, located in Snohomish County included paving along State Route 530 between milepost 35 to 36, 38 to 40, 42 to 48 as well as on several bridges along the corridor.

The asphalt on this stretch of SR 530 has outlived its anticipated lifespan. Through the years, cracks, ruts…

This section of SR 531 between 43rd Avenue Northeast and 67th Avenue Northeast in Arlington will be widened to add a second lane in each direction. In addition, roundabouts will be added at three intersections to improve safety, travel times and reduce congestion.

WSDOT improved the intersection of SR 9 and SR 204 in Lake Stevens by adding four roundabouts and widening SR 9 to two lanes in each direction immediately south of the intersection. These improvements help manage congestion and improve mobility, provide better access to area businesses and provide…

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…
