It is 174 feet long and 20 feet wide, and was built in 1889.","why_significant":"The bridge was built in 1889 after a flood, and it was originally known as Billows Bridge. The form lists it as part of a group of Perry County covered bridges considered in a thematic nomination. The document notes its construction followed an earlier bridge dated 1836.","narrative":"Built in 1889 by Andrew Clouser, this covered bridge crosses Shermans Creek in Wheatfield Township, Perry County, Pennsylvania. It uses a Burr truss system and measures 174 feet along its end posts and 20 feet in width, with a clearance of 11 feet 10 inches. The bridge was constructed in response to a flood that year, and an earlier bridge at the site is recorded as dating to 1836. It was originally known as Billows Bridge and carries a roadway of two-inch by sixteen-foot planking. A concrete center pier was added in 1932, and two 36-inch steel I-beams were installed in 1957 to strengthen it. The bridge was reviewed alongside other covered bridges in Adams, Cumberland and Perry counties, and it was judged to be eligible for the register. Its inclusion was discussed because it no longer crosses over water, a point the reviewers questioned.","period_of_significance":null,"architect_builder":"Andrew Clouser (builder)","architectural_style":"Burr truss","criteria":[],"status_note":"Reinforced with a concrete center pier in 1932 and with two 36-inch steel I-beams in 1957.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.916743-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003593.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003593/92198be363-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003593/92198be363-1600.webp","licence":"CC BY-SA 3.0","author":"Ken Gallager","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Dellville_Covered_Bridge_PA_2012.jpg\" rel=\"noopener\">Ken Gallager</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:Dellville_Covered_Bridge_PA_2012.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993444","wikipedia":"https://en.wikipedia.org/wiki/Dellville_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5254227"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/perry-county/dellville-covered-bridge-80003593/"}
