The bridge is 102 feet long between its end posts and about 15 feet wide. It was built in 1875 and is owned by Lancaster County. Its vertical plank siding and cut stone abutments are its most distinctive physical features. The bridge belongs to a group of covered bridges in Lancaster County that was nominated together as a thematic set, reflecting the county's surviving nineteenth-century timber bridge building. Reviewers noted that its stone abutments and trusses were in good condition, which supported its inclusion. The record reflects the bridge's construction, its setting over the creek, and its role as a representative example of the county's covered bridges.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as excellent.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.463266-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003538.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003538/3ed4f79d57-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003538/3ed4f79d57-1600.webp","licence":"CC BY-SA 2.5","author":"Photo by and (c)2006 Derek Ramsey (Ram-Man)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Neff%27s_Mill_Covered_Bridge_Side_View_3000px.jpg\" rel=\"noopener\">Photo by and (c)2006 Derek Ramsey (Ram-Man)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.5\" rel=\"license noopener\">CC BY-SA 2.5</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Neff%27s_Mill_Covered_Bridge_Side_View_3000px.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993245","wikipedia":"https://en.wikipedia.org/wiki/Neff%27s_Mill_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q14628962"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/neffs-mill-covered-bridge-80003538/"}
