US 101 - Hoquiam River - Riverside Bridge - Bridge Painting Approach Spans

Project news

  • This project was recently awarded to Panther Industrial Painting, LLC. Work is expected to begin Apri 26, 2021 and last through late fall. The contractor anticipate little affects on travelers during construction. Any lane closures will be announced in advance.
  • To extend the life of the bridge, crews must paint the bridge towers and perform general maintenance to the lift span. This portion of work has been deferred pending U.S. Coast Guard approval, and could not be combined into the first construction contract. 
  • During a routine inspection, WSDOT bridge crews discovered damage to the top of the elevator that will also require repairs. A third project to mechanically rehabilitate the elevator space is expected to be advertised for competitive bids in the fall of 2021.  
  • Travelers are encouraged to sign up for email alerts.

Needs & benefits

The 465-foot-long, US 101 Hoquiam River Riverside Bridge is in need of a new protective surface. During the summer of 2021, contractor crews willl repaint the bridge's approach spans to preserve the crossing for years to come. Bridge painting, rehabilitaton, and routine maintenance is more cost effective than replacement. 

To do this important work, crews will construct a containment system around the bridge to help protect the environment. General work activities include: cleaning, stripping exterior paint and rust, and repainting the surface of the bridge. Marine travelers, including those who walk and roll, are expected to experience minimal delays.  Crews will maintain a single travel lane through project completion.

Built in 1970, this moveable bridge in Grays Harbor County requires maintenance to keep operational for travelers. WSDOT understands the importance of the 50-year old crossing to the local community, and will work to minimize disruptions as much as possible during construction. 


  • Feb. 2021 - Project awarded to Panther Industrial Painting, LLC.
  • Summer 2021: Construction begins
  • Late fall 2021: Project mostly complete
