Know your county roads

Interactive map of county roads

You’ll find most county-maintained roads in:

  • Rural parts of east and west Multnomah County
  • Urban pockets within the county but outside cities such as Portland and Gresham
  • Larger roads (called collectors and arterials) in and near Fairview, Troutdale, and Wood Village

Keep in mind only a few roads in your area probably belong to the county. For example, the city of Portland has more than 2,000 miles of roads — compared to about 274 miles for the county. Check the maps for the ones near you.

Note: Bridges over the Willamette River aren’t included in the Roads Capital Improvement Plan. They have a separate plan.

How is the public involved?

Public input was considered at each phase of the project, which concluded in January 2020 when the plan was adopted by County Commissioners. 

What kinds of projects are in the RCIP?

The RCIP is about improving roads with added features such as guardrails, wider shoulders or improving culverts that carry streams under roads. Maintaining roads, such as filling potholes, has a separate plan and separate funding.

Projects included in the RCIP could include:

  • Widening roads for more lanes (lanes to travel in, or turn lanes)
  • Widening shoulders for people walking and biking
  • Adding signals or other projects to make intersections easier and safer
  • Guardrails
  • Multi-use paths
  • Culvert replacements
  • Bridge improvements

What’s not included:

  • Maintaining roads, such as filling potholes
  • Improvements to bridges over the Willamette River (they have a separate plan.)

Also, the RCIP is different from the Transportation System Plan (TSP) completed in 2016. The TSP gives the big picture, while the RCIP zooms in for details — from you.
