Short Significance Description:
Entrance road is eligible for local sign. for its assoc. w/ early development of the monument's transportation system & representative of a pattern of building activity w/ CCC assist. in the 1930s (Crit. A); (Crit. C), development of NPS landscape & road construction. Period of significance 1934-50.
Long Significance Description:
The entrance road is associated with the Devils Tower National Park Multiple Property Submission themes, "Administration and Development of Devils Tower National Monument, 1906-1950" and "National Park Service Rustic Architecture and Public Works Construction in Devils Tower National Monument, 1933-1940." The road was also evaluated under the historic context, "Historic Landscape Design in the National Park Service, 1916 to 1942," contained in Linda McClelland's Historic Park Landscapes in National and State Parks multiple property submission. The entrance road is eligible for listing at the local level of significance under criterion A, for its association with the early development of the monument's transportation system. The effort to develop and improve the transportation system at Devils Tower National Monument is representative of a pattern of activity found throughout the National Park Service during the 1930s. It is also significant for its association with the "New Deal" programs of the Great Depression. Such development would not have been possible without the funding made available by a variety of public works programs, nor without the labor of the Civilian Conservation Corps.

The entrance road is also eligible for listing under criterion C, as design, placement, slope contouring, associated structures (masonry headwalls and retaining walls), and revegetation clearly illustrate the naturalistic design philosophy of road construction developed by National Park Service during the 1920s and 1930s. The concern for providing visitor access to park areas while minimizing the impact to the landscape underlay the design, construction, and roadside landscaping efforts made throughout the NPS in road building activities predating World War II.

The areas of significance for the entrance road are Politics/Government (association with development of a national park), Social History (association with the public works programs of the Great Depression), Transportation (as the primary access route into the park) and Landscape Architecture (as exemplifying NPS naturalistic design philosophy of the 1930s). The period of significance dates from 1934, when the original 1917 road was reconstructed, to 1950, the end of the historic period as defined by the National Register of Historic Places.

Long Physical Description:
Entrance road is a 3-mile long, two-lane, asphalt paved road that spans the distance between the Entrance Station and the visitor parking area located just west of Devils Tower. The road provides access to the monument's primary developed areas, such as headquarters and visitor center.

A 3" bituminous crown covers a 9' aggregate base course. Portions of the upslope, round bottom ditch aside the road are paved. The road varies in width from 20 feet to 22 feet with a one foot shoulder (except portions of the road located east of the bridge where shoulders are about 10 feet). Both historic and modern features occur along the road: Belle Fourche River Bridge, paved parking or viewing pull-outs, five drainage inlets, entrance station, culverts, and retaining walls.
