Oleson Road Bridge over Fanno Creek

This project replaced the Oleson Road bridge over Fanno Creek. The previous bridge would often flood during high water events, requiring the bridge to be closed until water recedes. Due to the regular flooding, the bridge’s timber beams were in poor condition also contributing to the need to replace the bridge.

Bridge replacement improvements included:

  • Constructing the bridge above flood levels
  • Constructing the bridge to match up to the future Oleson Road realignment project
  • Completing the 400 foot roadway gap between the bridge and the previous Oleson Road improvement project that ended near Dover Street

Oleson Road was closed at Fanno Creek for 8 months. The road reopened to traffic at 3:30 p.m. on March 26, 2015.

This bridge replacement was originally scheduled to be replaced as part of the Oleson Road Realignment Project. At this time, funding for right-of-way acquisition and construction has not been identified for the realignment project. However, the county applied for and was awarded a federal funding match for the bridge replacement portion of the realignment project.
