It is also notable for decorative S-shaped metal designs at the truss ends, unusual on a narrow township road.","narrative":"Spanning a drainage ditch on Smith Road in Lykens Township, this small bowstring arch truss bridge dates to 1890. It has one span of 41 feet clear, an overall length of 45 feet 6 inches, and a roadway 14 feet wide. Five panels of varying length, vertical hangers and diagonal braces support the deck, and the structure rests on two stone wall abutments. Curved metal S-shaped ornaments extend beyond the trusses at each end. The county's records identify no manufacturer, and no plate is found on the bridge, though the form suggests it may be a King Patent Tubular Arch from the King Iron Bridge and Manufacturing Company of Cleveland, possibly moved to the site in 1890. The bridge is considered the oldest in Crawford County and the only bowstring arch truss there. Its small size, compared with the typical 70 to 175 feet, and its decoration on a minor township road add to its interest. Light traffic has helped keep it in good repair.","period_of_significance":"1890","architect_builder":null,"architectural_style":"Bowstring arch truss","criteria":[],"status_note":"Listed in good condition, unaltered and on its original site; it carries very little traffic and is publicly owned and accessible.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.66798-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80002973.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987329","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/crawford-county/smith-road-bridge-80002973/"}
