Route 66 National Historic Trail Designation Act

S 2506 designates the historic Route 66 (from Chicago to Santa Monica, 1926-1985) as a National Historic Trail under the National Trails System Act. It specifies that the trail spans approximately 2,400 miles and requires the Secretary of the Interior to manage it while respecting its character, consulting with affected tribes, and explicitly prohibiting new land acquisition, buffer zones, or disruptions to existing energy development or transportation. The bill clarifies this designation does not create new federal land ownership, alter existing rights-of-way authority, or classify Route 66 as part of the National Park System.
