THE PURPOSE OF PARK ROADS
Functional Classifications of Park Roads
A park road system includes those roads within or providing access to a park or
other unit of the national park system, which is administered by the National
Park Service, or by the National Park Service in cooperation with other
agencies. For purposes of functional classification, the routes that constitute
a park road system are broadly grouped, based on use, into three principal
categories: public use park roads; administrative park roads; and urban parkways
and city streets. Each category has further subdivisions or classes based on the
assignment of a functional classification to a park road. Road classification is
not based on traffic volumes or speed, but on the intended use or function of
that particular road or route.
Public Use Park Roads
All park roads that are intended principally for the use of visitors for access
into and within a park are designated as a Public Use Park Road. This includes
all roads that provide vehicular passage for visitors, or access to such
representative park areas as to points of scenic or historic interest,
campgrounds, picnic areas, trailheads, and similar features. County, state and
U.S. numbered highways maintained by the National Park Service are included.
Administrative Park Roads
The Administrative Park Road category consists of all public and nonpublic roads
intended to be used principally for administrative purposes necessary to carry
out management objectives for the particular area. It includes roads servicing
employee residential areas, maintenance areas, and other administrative
developments as well as patrol roads, truck trails, and similar administrative
roads.
Urban Parkways and City Streets
These facilities serve high volumes of park and nonpark-related traffic and are
restricted, limited-access facilities in an urban area.
Functionally, because it provides access for visitor use and administrative
needs, Highway 62 West in Crater Lake National Park is classified as a Public
Use and Administrative Park Road.
