Capital Improvement Plans
Capital Improvement Plans are long-term plans for improving our roads and bridges.
We are responsible for six bridges over the Willamette River. We also maintain about 269 miles of roads. Many of these roads are rural, but some are in urban pockets outside of any city. A few are larger, busier roads in and around Fairview, Troutdale, and Wood Village.
A Capital Improvement Plan identifies what improvements or upgrades are needed on our roads and bridges, and ranks them by priority. With limited transportation funds, this helps us decide which projects to pursue.
We reached out to the public to help create these plans, with public meetings and surveys. We interviewed public agencies and other people and groups that had a stake in the plans. Finally, the plans were presented to the Board of County Commissioners, who voted to adopt them.

Transportation System Plan
The Transportation System Plan (TSP) is the master plan for how the County’s rural transportation system will evolve and develop. It only includes county roads outside of cities. The plan’s primary focus is on enhancing the safety of the transportation system and balancing the needs of agricultural, visitor, residential, bicycle, pedestrian, and freight travel to and from the rural areas.
The TSP was published in 2016, and covers a period of twenty years. The projects in this plan were included in the Roads Capital Improvement Plan, as were projects from TSP's prepared by the cities of Troutdale, Wood Village and Fairview.
