Traffic Impact

​Expect delays and occasional lane closures.

Construction Impacts

We are working mostly during the daytime. There will be times when work will be done at night.

Construction is estimated to complete in 2023.

Construction Activities

​We are currently building the new bridge and will shift traffic as needed.

Pedestrians, including those with disabilities, will have access through and around work zones. 



The project includes replacing the existing culvert with a single span concrete deck bridge. The new bridge will create an easier passage for native migratory fish like salmon and steelhead, some of which are listed as endangered species. Improving fish passages aligns with our commitment to the Oregon Plan for Salmon and Watersheds.

Project Details:

  • Remove the old culvert.

  • Install a new single span bridge.

  • Reconstruct the streambed to encourage native fish migration.
