The bill would designate the Route 66 National Historic Trail, covering alignments of U.S. Highway 66 existing between 1926 and 1985 along an approximately 2,400-mile route from Chicago to Santa Monica. The Secretary of the Interior, acting through the National Park Service, would administer the trail and conduct specified tribal consultation before activities with substantial direct impacts on affected tribes. Land acquisition would require owner consent outside federally managed areas, be limited to an average of one-quarter mile on either side, and could not use eminent domain; the designation would not create buffer zones, prohibit energy development, designate national park lands, or require new federal permits.
