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

Project news

  • The originally published scope of work for the US 101 Hoquiam River Riverside Bridge has been modified to address the most pressing work first that does not require extensive permits and approvals. This project is intended to paint the bridge's approach spans (which have the greatest need) with a future project to paint the towers and lift span. The second project has not been prepared for advertisement yet and will require more extensive approvals by the U.S. Coast Guard. 
  • This project repaints the nearly 50-year-old crossing to preserve and protect the structure for years to come. Bridge painting is more cost-effective than replacement.
  • Drivers who use this bridge, including those heading to the coast, should expect delays and are encouraged to sign up for email alerts.

Needs & benefits

The 465-foot, US 101 Hoquiam River Riverside Bridge in Grays Harbor County was built in 1970 and is in need of a new protective surface. Bridge painting preserves the overall integrity of the structure and is more cost-effective than replacement. In addition, cleaning and repainting the bridge prevents flaking paint and rusting metal from falling into the Hoquiam River.

The project will require crews to build a containment system around the bridge to help protect the environment.  Workers will then clean, strip and remove rust, and ultimately repaint the bridge. This project will have minimal impacts to boating traffic and single lane of traffic maintained around the clock through completion.
