The form records a built year of 1869 and a truss type described as a Burr arch combined with Queen post trusses.","why_significant":"The form describes the bridge as an unusual combination of Burr arch and Queen post trusses. It is one of the covered bridges in Perry County nominated as part of a multiple-resource group. The bridge has been reinforced with two steel I-beams, and the roadway is planked.","narrative":"Built in 1869 over Sherman's Creek in Tyrone Township, near Landisburg, Perry County, this covered bridge carries a local road across the creek. Its structure combines two truss systems, a Burr arch and Queen posts, a pairing the nomination describes as unusual. The span is about 152 feet long and 28 feet wide, with a roadway of two-inch planks laid across the deck. Two steel I-beams were added to reinforce the structure, and the bridge has a clearance of 13 feet and a posted load limit of 4 tons. It was listed in 1980 as one of a group of covered bridges in Adams and Perry Counties, with the reviewers judging the group eligible and the boundaries and repairs adequate for the purpose. The bridge is significant chiefly as an example of a mixed truss design in Pennsylvania's covered bridge tradition.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr arch and Queen post truss combination","criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.873302-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003596.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003596/b70d686e1f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003596/b70d686e1f-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Rice_Bridge_Perry_Co_1.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Rice_Bridge_Perry_Co_1.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993438","wikipedia":"https://en.wikipedia.org/wiki/Rice_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7322997"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/perry-county/rice-covered-bridge-80003596/"}
