It is a stone-arch structure with semi-circular arches and coursed unfinished stone faces.","why_significant":"The nomination argues the bridge is significant under Criterion A for its association with local transportation in Huntingdon County, and under Criterion C as a fine example of a stone-arch bridge. It is described as a good example of a nineteenth-century multiple-span stone arch bridge built by the Pennsylvania Railroad, representing the second phase of the railroad's bridge construction. It is evaluated on a local level.","narrative":"Built in 1889 by the Pennsylvania Railroad, this 134-foot cut stone bridge has three semi-circular arches and carries the two-track line over Shavers Creek near its junction with the Juniata River at Petersburg, Huntingdon County. Its faces are coursed, unfinished stone, and the undersides of the arches have step-like ribbing for support. Metal brackets supporting curbing on the south face and metal safety railings on the deck were added later, with the brackets likely dating to repairs made in 1967. Records show six stone-arch railroad bridges were built in the county between 1886 and 1889, suggesting the railroad was replacing earlier iron bridges with heavier masonry. It is regarded as a good example of a nineteenth-century multiple-span stone arch bridge, and its integrity is considered sufficient to convey that significance. It is the only stone-arch railroad bridge in the county still in use that has not received concrete supports on its face.","period_of_significance":"1889-1939","architect_builder":"Pennsylvania Railroad","architectural_style":"Other: stone arch bridge","criteria":["A","C"],"status_note":"Still in use; most recent major repairs were made in 1967.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.75066-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/90000395.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000395/c81d286ced-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000395/c81d286ced-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_Bridge_over_Shavers_Creek_in_Petersburg_PA.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_Bridge_over_Shavers_Creek_in_Petersburg_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993073","wikipedia":"https://en.wikipedia.org/wiki/Pennsylvania_Railroad_Bridge_over_Shavers_Creek","wikidata":"https://www.wikidata.org/wiki/Q15265914"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/huntingdon-county/pennsylvania-railroad-bridge-over-shavers-creek-90000395/"}
