It is described as identical in style to the Haupt's Mill Bridge. The bridge is noted as being on the route of the Walking Purchase.","narrative":"Knecht's Covered Bridge is a wooden covered bridge crossing Durham Creek in Springfield Township, Bucks County, Pennsylvania. Built in 1873, it spans 110 feet and is 15 feet wide. Its Town truss is framed in hemlock, and the structure is regarded as an example of the wooden bridge building of its period. The bridge is identical in style to the nearby Haupt's Mill Bridge, which makes the two useful for comparison. Its route follows the line of the Walking Purchase, the disputed 1737 land transaction between the Penn family and the Lenape that shaped settlement in the region. The bridge is listed for its engineering and construction value as a surviving example of a bridge type once common across Bucks County. It remains in good condition, and its preserved form gives a clear picture of how such crossings were built in the nineteenth century.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Good condition, as stated in the document.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.378862-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003432.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003432/1987013141-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003432/1987013141-1600.webp","licence":"CC BY-SA 3.0","author":"PattiParker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Knecht%27s_Covered_Bridge_2.JPG\" rel=\"noopener\">PattiParker</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Knecht%27s_Covered_Bridge_2.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992462","wikipedia":"https://en.wikipedia.org/wiki/Knecht%27s_Mill_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6421838"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/knechts-mill-covered-bridge-80003432/"}
