Get to Know the Region
Region 5 builds, operates and maintains the state’s multimodal transportation system in eastern Oregon.
The region is home to less than five percent of Oregon’s population but includes around one-third of the land in the state and shares a border with three neighboring states: Washington, Idaho and Nevada. Seven counties in this region include Morrow, Umatilla, Union, Baker, Wallowa, Grant, Malheur and Harney.
Geographically, this region includes vast high desert, mountain passes and the Columbia River Basin. Throughout the year, wind, wildfires, flooding, landslides and snow present challenges for a region with two primary interstate routes — I-84 and I-82 — and no good alternatives for freight movement. Extreme weather events often lead to numerous and extended closures, and winter maintenance is required for six months out of the year. With great distances between towns in some areas of the region, a safe and reliable transportation system is a must.
