U.S. Forest Service logoForest Highways (sometimes referred to as "Federal Forest Highways") are "forest roads under the jurisdiction of, and maintained by, a public authority and open to public travel." These highways are designated by the United States Forest Service (USFS) and funded by the federal government, but are often maintained by state or local agencies, such as the Michigan Department of Transportation (MDOT) or the County Road Commissions in Michigan.

Federal Forest Highway 13 route markerNationwide, the Forest Highway system contains about 30,000 miles of roads and 4,214 bridges. States own and maintain 45% of these routes, counties another 48%, with the Forest Service itself owning and/or maintaining the rest. In order to qualify for federal funding under this system, a road must "be wholly or partially within, or adjacent to, and serving the National Forest System" and be nominated and selected as a federally-designated “Forest Highway” which also includes National Forest Scenic Byways. An example of the Federal Forest Highway route marker appears at right. Examples of the various Forest Highway and Forest Road signage can be found on the Route Markers page.

National Forests feature several types of numbered routes and roads, each one of them designated and signposted for inventory and navigational purposes. Types of numbered transportation facilities in National Forests include Forest Highways, Forest Roads, and Forest Trails, each providing for a different level of accessibility. Note that this website only attempts to catalogue the Forest Highways—those primary access routes providing all-weather access to all types of vehicles and that are oftentimes paved.

Forest Highway History

The first federal funding for roads and trails serving National forests was provided by the 1916 Federal-Aid Road Act. The Federal-Aid Highway act of 1921 further divded forest roads and trails into two main classes: Forest Highways and Forest Development roads and trails. Forest Highways were defined as public roads owned by State or local agencies serving the National Forest System, while Forest Development roads were owned by the Forest Service itself. The designation of Forest Highways was done by the Federal Highway Administration's (FHWA) Federal Lands Highway Division enginers in consultation with State departments of transportation, local agencies, and the Forest Service.

A General Accounting Office (GAO) report in 1977 directed the FHWA and USFS to " jointly assure that transportation needs of the National Forest system were adequately considered when projects were being selected." Because of this, the Federal-Aid Highway Act of 1978 contained an amended definition of "Forest Highway." Further legal modification came in 1982 when the a federal statute (Public Law 97-424) provided for allocating Federal Highway funds according to the relative needs of the National Forest instead of simply apportioning those funds to the States. Federal funding apportionments were modified again in 1987 and 1991, in part directing the funds to be allocated by Forest Service Regions.

In 2012, however, the Forest Highway Program (FHP) was eliminated under "Moving Ahead for Progress in the 21st Century Act" (MAP-21), the federal funding legislation that replaced SAFETEA-LU which, along with ISTEA, had simply continued the program forward from previous funding legislation. Any Forest Highway project authorized under SAFETEA-LU and any funds carrying over from the previous legislation were to remain administered under the previous rules and regulations of the Forest Highway Program, however.

The replacement for the Forest Highway Program under MAP-21 is the Federal Lands Access Program (FLAP) which provides funds for projects on Federal Lands access transportation facilities located on, adjacent to, or providing access to Federal lands. A Federal Lands access transportation facility is defined as "a public highway, road, bridge, trail, or transit system that is located on, adjacent to, or provides access to Federal lands for which title or maintenance responsibility is vested in a State, county, town, township, tribal, municipal, or local government." FLAP is very similar to the FHP, except that instead of being targeted solely toward transportation facilities providing access to National Forests, the new program centers on facilities giving access to any Federal Lands, including lands managed by the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management, and the U.S. Army Corps of Engineers.
