Construction Impacts

Thank you for your patience as we worked to replace the West Fork Dairy Creek Bridge on OR 47 in Banks.  

The bridge has been replaced and the road is opened to traffic. We apologize for the delay.

We installed a temporary asphalt surface to get the road reopened.

The permanent bridge surface will be a polymer concrete that requires specific weather conditions to install and for the material to set. Using polymer to bind the concrete makes it less likely to crack, more durable and resistant to conditions caused by changes in the weather.  

Warm and dry weather is needed to install this type of bridge surface, so we'll need to return in the spring to complete the project. 

Construction Activities

Later this year, we will return to remove the temporary asphalt bridge surface and replace it with the permanent concrete bridge surface.

​Pedestrians, including those with disabilities, will have access through or around the work zone. 



The project is located at West Fork Dairy Creek on OR 47 west of Banks. The existing bridge is currently more than 80 years old and its timber deck is in poor condition. We are replacing the deteriorated timber bridge with a new single span bridge. We are also realigning the creek to prevent downstream bank erosion by adding vegetation and boulders along the sides of the creek. ​

​The work includes:

  • Replacing the bridge and repaving the roadway.

  • Replacing guardrail.

  • Installing new striping and traffic signs.

  • Stream improvements and erosion protection.​
