Region 4 Central Oregon

The Oregon Department of Transportation's Region 4 extends from the Columbia River to the California border and from the crest of the Cascade Range into the Oregon High Desert. It is responsible for the construction, operation and maintenance of US and Oregon highways in this area.
Our mission is to keep motorists safe as they make their way along our highways to engage in the social, cultural, and economic activities that make Central Oregon a vibrant and exceptional place to live, work and play.
