US 101 - Hoquiam River - Riverside Bridge - Bridge Painting

Project news

  • This project's advertisement date has been delayed until winter 2019 pending Coast Guard approval and additional maritime public outreach. 
  • Crews will repaint the nearly 50-year-old, US 101 Hoquiam River Riverside Bridge to preserve and protect the structure for years to come. Bridge painting is more cost-effective than replacement.
  • Travelers will still be able to cross the bridge.
  • A containment system will be installed around the entire surface of the structure to protect the environment, while one single lane of traffic will be maintained around the clock until project completion.
  • 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 will 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 no impacts to boating traffic.
