It was built in 1871 and measures 104 feet along its end post. The structure has vertical plank siding, a gable roof and plain triangular portals. Its truss form is a combination of arch and truss elements built with timber frame construction, a method common among 19th-century covered bridges in the region. The bridge was reviewed as one member of a group of covered bridges in Lancaster County that together illustrate the range of timber truss types used in that period. Reviewers regarded its trusses as being in good condition, and its condition is recorded as excellent. The review also noted that boundaries needed adjustment to encompass the abutments fully.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr arch truss","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 17:11:34.356743-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003535.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003535/9e2fea209a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003535/9e2fea209a-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:Lime_Valley_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:Lime_Valley_Covered_Bridge_Side_View_3000px.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993239","wikipedia":"https://en.wikipedia.org/wiki/Lime_Valley_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q14628961"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/lime-valley-covered-bridge-80003535/"}
