Project news

  • View construction progress photos
  • The contractor has plans to begin preparatory work at the site beginning the week of May 6. Traffic impacts (one-way alternating with a signal) could begin as early as mid-June and remain in place throughout the duration of the project. The bridge will remain open to all motorists, including legal-loaded semis. Travelers should expect occasional night and full weekend closures during construction.
  • Oversized and overweight vehicles may need to use an alternate route. Please contact Commercial Vehicle Services to determine if an alternate route is necessary. 

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.

Needs & 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.
