Built around 1873, the bridge is about 130 feet long, 15 feet wide, and has a clearance of 12 feet 1 inch. It is owned by the Commonwealth of Pennsylvania. Its form is regarded as typical of the covered bridges built in Bucks County during the nineteenth century, and it serves as an example of local wooden bridge technology from that period. It was included in a group of covered bridges in the Delaware River watershed that were evaluated together for their architectural importance. At the time of the listing the bridge was in poor condition, which the document identifies as a concern for its survival.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition is rated poor 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 17:11:33.272-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003445.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003445/7a1562b756-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003445/7a1562b756-1600.webp","licence":"CC BY-SA 3.0","author":"PattiParker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Sheard%27s_Mill_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:Sheard%27s_Mill_Covered_Bridge_2.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992478","wikipedia":"https://en.wikipedia.org/wiki/Sheard%27s_Mill_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7492184"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/sheards-mill-covered-bridge-80003445/"}
