Status

  • During construction, the bridge will remain open to local traffic. Local drivers will encounter one-way alternating traffic. In addition, local drivers can also expect occasional night and full weekend closures. WSDOT will announce in advance when those closures are scheduled.
  • All other traffic, including truck traffic, will be detoured around the bridge during construction.
  • Thank you to all who attended the SR 107 Chehalis River Bridge open house on Tuesday, Sept. 13.  Your comments will help guide the final design of this project.

Why is WSDOT rehabilitating the SR 107 Chehalis River Bridge?
The 58 year-old SR 107 Chehalis River Bridge located south of Montesano in Grays Harbor county is in need of repairs. This project will replace the timber on the south approach to the bridge, install modern safety rails, and paint the steel structure on the bridge.

The End Result
A rehabilitated SR 107 Chehalis River Bridge will reduce maintenance costs. New paint will help preserve and protect the bridge against corrosion.

Project Benefits

  • Reduce maintenance frequency and costs by replacing the deteriorated timber approach trestle with a concrete structure.
  • Reduces severity of collisions by installing modern traffic barriers and guardrail.
  • Preserves the steel trestle by painting.

What is the project timeline?

  • Fall 2016: Finalize structure rehabilitation plan.
  • Spring 2018: Construction
