It includes 83 contributing resources, mostly one-part commercial blocks.","why_significant":"The district is described as Amarillo's most intact collection of commercial buildings tied to U.S. Route 66. Gravel paving in 1921 and the 1926 Route 66 designation spurred commercial growth that continued until the highway moved off the street in 1953. It is significant at the state level for Transportation and Community Planning and Development, and for its distinctive urban form.","narrative":"Sixth Avenue, locally called Sixth Street, runs through the San Jacinto Heights Addition west of downtown Amarillo, and a 13-block stretch of it forms a historic district tied to U.S. Route 66. The street was platted in 1909 but saw little building until gravel paving in 1921 improved the Ozark Trail route. After Route 66 was designated in 1926, shops, service stations, cafes and bungalows went up to serve both neighborhood residents and travelers. Most buildings are modest one-part commercial blocks, with Spanish Colonial Revival, Art Deco and Art Moderne details. A 1942 street widening altered some storefronts, and the highway moved off the street in 1953. Of 116 resources, 83 contribute to the district, including the roadway, Depression-era sidewalks and a hanging traffic light. It was recognized as Amarillo's most intact collection of buildings associated with the highway, with a period of significance of 1921 to 1953.","period_of_significance":"1921-1953","architect_builder":"Carlander, Guy Anton (architect); Randall, Albert (builder)","architectural_style":"Other: One-part Commercial Block; Late 19th and 20th Century Revivals; Modern Movement","criteria":["A","C"],"status_note":"Many buildings remain in commercial or residential use; revitalization and restoration work since a 1989 study has returned some buildings to a historic appearance.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:23.908741-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/20/9732/40973220/content/electronic-records/rg-079/NPS_TX/94000982.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40973220","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q109999541"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/potter-county/us-route-66-sixth-street-historic-district-94000982/"}
