SR 529/Snohomish River & Steamboat Slough - Bridge Repair, Rehab & Paint

The northbound SR 529 Snohomish River Bridge is reduced to one lane, 24 hours a day, until June 1.

From June 1 until early October, SR 529 will be reduced to one lane in each direction at the Snohomish River. The northbound SR 529 Snohomish River Bridge will be closed. The southbound SR 529 Snohomish River Bridge will be reconfigured to carry one lane of traffic in each direction with a reduced speed limit.

Project overview

Corrosion from weather is damaging the Snohomish River Bridge and Steamboat Slough Bridge. Beginning in 2023, crews working for WSDOT will rehabilitate the northbound SR 529 Snohomish River Bridge between Everett and Marysville by repairing or replacing steel truss elements, substructure elements, sway frames, timber sidewalks, cleaning and painting metal surfaces, and mechanical and electrical rehabilitation. Crews will also perform rehabilitation work to the SR 529 Steamboat Slough Bridge in both directions to ensure the end lift upper wheels work properly and the movable span is balanced.

What to expect

SR 529 travelers can expect:

Northbound SR 529 Snohomish River Bridge:  From June 1 until early October, SR 529 in north Everett will be reduced to one lane in each direction at the Snohomish River. The northbound SR 529 Snohomish River Bridge will be closed. The southbound SR 529 Snohomish River Bridge will be reconfigured to carry one lane of traffic in each direction with a reduced speed limit.

The East Marine View Drive on-ramp to northbound SR 529 will also be closed during this four-month period. Traffic will be directed through local streets to get back on the northbound SR 529. Access from northbound SR 529 to Smith Island and Spencer Island will be open.

A shuttle will take bicyclists past the work zone.

There will also be about four months of lane reductions and multiple weekend full closures on the northbound SR 529 Snohomish River Bridge. Traffic will be diverted to northbound I-5 as an alternative route during weekend full closures.

Southbound SR 529 Snohomish River Bridge:  Beginning June 1, the southbound SR 529 Snohomish River Bridge will be reduced to one lane of travel in each direction, with a reduced speed limit. Local access to the tribal lands will be open.

Northbound SR 529 Steamboat Slough Bridge: 
There will be two four-day full closures of the road and waterway. Traffic will be diverted to northbound I-5 during the continuous full closures. Access from northbound SR 529 to Smith Island and Spencer Island will be open.

Southbound SR 529 Steamboat Slough Bridge:
There will be numerous overnight closures of the roadway and the waterway. Some weekend-long closures are possible; if these occur traffic will be diverted to southbound I-5. Local access to tribal lands will be open.

This project includes work on the northbound Snohomish River Bridge and both directions on the Steamboat Slough Bridges.
