Forest Highways orForest Routes are a category ofroads withinUnited States National Forests. They are built to connect the national forests to the existing state highway systems, and to provide improved access to recreational and logging areas.
United States federal law defines the termForest Highway as "a forest road under the jurisdiction of, and maintained by, a public authority and open to public travel."[2] Forest highways are designated by theUnited States Forest Service and funded by thefederal government, but are generally owned and maintained by thestates orcounties in which they are located. The forest highway system comprises approximately 29,000 miles (47,000 km) of roads.[3] Forest highways are usually marked with markers in the shape of anisosceles trapezoid, wider at the top and narrower at the base. The shields are brown with a white border and divided by a horizontal white line. In the majority of the space (above the line), the number of the route appears in whiteHighway Gothic numbers, while in the smaller space below the line is written "National Forest" in the cursiveForest Servicelogotype used to write "National Forest" on national forest gateway signs. To qualify for inclusion in the system, a roadway must "be wholly or partially within, or adjacent to, and serving the National Forest System" among other criteria.[4]
In the 1920s, forest highway was a class offederal aid, and could be used outside forests, as long as the projects improved access to the forests.[5]
