Overview 
Contractor crews will clean and paint the northbound State Route 529 Steamboat Slough Bridge between Everett and Marysville to help preserve the structure.

Why is WSDOT painting the northbound SR 529 Steamboat Slough Bridge?
Steel truss bridges need to be regularly cleaned and painted to preserve their integrity and keep them in good working condition. The northbound SR 529 Steamboat Slough Bridge was built in 1954 and last painted in 2002. The paint is currently flaking and peeling away, exposing the steel to air and water, which has resulted in rust and corrosion.

How will the work be done?
Due to the bridge's size, work will be done in sections. Crews will encase a section of the bridge with a containment system to protect the surrounding areas from exposure to construction activities that will include cleaning, painting, debris removal and cleanup.

The contractor will then clean the bridge and remove the old paint by sandblasting it until the bare metal of the bridge is exposed. When that is complete, new primer and paint will be applied. As sections are completed, crews will move to another area of the bridge and repeat the process.

Crews will likely work from platforms they will install below the bridge deck. The painting work is wind sensitive.

Bridge openings to be restricted
The movable section of the bridge will not be able to operate with the added weight of the containment system. Mariners should plan ahead for a long-term maritime closure of Steamboat Slough as bridge openings will be prohibited for several months.

The End Result
The bridge will have a new coat of paint that will help prolong the life of the structure by protecting it from rust, corrosion and the birds that frequently nest on the bridge.

Project Benefits

  • Preservation: This work helps protect the bridge from corrosion while preserving the bridge's structural integrity.
  • Economic: Maintaining the bridge is more cost-efficient that replacing it. Maintained properly, the bridge will continue to keep up with the high demand of traffic for years to come.

What is the project timeline?

  • February 2017: Project was advertised for competitive bidding.
  • March 2017: Project was awarded to Abhe & Svoboda, Inc.
