It was nominated as part of a thematic group of covered bridges in the county, and the form records the trusses as being in good condition.","narrative":"Landis Mill Covered Bridge crosses Little Conestoga Creek on the line between East Hempfield and Manheim townships in Lancaster County, Pennsylvania. Its date is recorded as 1878. The bridge is a wooden covered structure with a kingpost truss, and its span is 53 feet, with a roadway width of about 15 feet. Its truss form is multiple kingpost, a type regarded as uncommon for Lancaster County. The bridge is one of a group of covered bridges in the county that were considered together, as a thematic set of 19th-century wood-frame structures. Reviewers noted that the bridge was in good condition, and that its abutments and boundaries needed to be checked before the listing could be confirmed. The record does not name a builder or architect. The document is a short nomination form with limited narrative, so the description is brief and relies on the basic physical and technical details it provides.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition recorded as good.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.399595-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003526.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003526/c611dc4ab6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003526/c611dc4ab6-1600.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:Landis_Mill_Covered_Bridge_Side_View_3264px.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:Landis_Mill_Covered_Bridge_Side_View_3264px.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993251","wikipedia":"https://en.wikipedia.org/wiki/Landis_Mill_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q6484667"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/landis-mill-covered-bridge-80003526/"}
