Oleson Road Bridge over Fanno Creek

This project will improve Oleson Road between Dover Street and Beaverton-Hillsdale Highway, including replacement of the bridge at Fanno Creek.

Improvements include:

  • One travel lane in each direction with a center turn lane
  • Bike lanes and sidewalks on both sides of the road
  • Street lighting
  • Drainage facilities
  • Landscaping

In coordination with Raleigh Water District, their existing waterline that falls within the project limits will be temporarily relocated by the bridge contractor and subsequently mounted under the new bridge. Waterline work will be funded by the water district.
