Scope and Content Note
The Highway Maps of Oregon Counties consist of maps for all 36 Oregon counties produced by the Oregon Highway Division in cooperation with the Federal Highway Administration. One or more sheets for each county depict roads and bridges; railroads and airports; structures such as tanks, sawmills, and power plants; recreational facilities; rivers, streams, dams, and fish hatcheries; and other features. In addition, additional sheets for each county include orthophotographs (aerial images) for developed areas of the county, primarily cities and towns, with highways, rivers, and other features highlighted.
The maps are of interest because they document Oregon in the few years preceding and following the adoption of land use planning through Senate Bill 100 in 1973.
