It is now known as Texas Farm Road 2161.","why_significant":"The nomination argues the segment reflects the history of Route 66 as a leading mid-20th-century highway between Chicago and California (Criterion A). It also represents roadbed construction and engineering of the 1930s (Criterion C). It is described as one of the longest and best preserved Route 66 sections in Texas, with the highest integrity of any rural section in the state.","narrative":"This 7.2-mile stretch of old Route 66 runs west from Conway, in the Texas Panhandle, toward Interstate 40 through open rangeland and farmland. It was designated as Route 66 and paved with concrete in 1930, after a dispute over the route through Carson County was settled. The original roadbed is about 19 feet wide with narrow shoulders, and the concrete was later covered with asphalt around 1950. It carried the highway until about 1965, when Interstate 40 was completed to the north, and it then joined the county road system as Texas Farm Road 2161. It is still used for local traffic. The nomination presents it as a representative example of 1930s roadbed engineering and as a reminder of Route 66's role as a major corridor between Chicago and California. The surrounding landscape, with scattered farm buildings, windmills and an abandoned railroad bed, has changed little, giving the road one of the highest levels of integrity of any rural Route 66 section in Texas.","period_of_significance":"1930-1957","architect_builder":"unknown","architectural_style":"No style","criteria":["A","C"],"status_note":"Still in use as a roadbed for local traffic as Texas Farm Road 2161, owned by the Carson County Highway Department.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:23.309944-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/9/9685/40968509/content/electronic-records/rg-079/NPS_TX/06000924.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40968509","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q109999831"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/carson-county/route-66-tx-207-to-i-40-06000924/"}
