It also notes the bridge became well known through Currier and Ives lithographs of 1860.","narrative":"Built in 1813 by Philip Diehl over Jack's Creek in Mifflin County, this one-span semi-elliptical stone arch bridge carries long, curving abutments. The bridge measures 123 feet 5 inches in length, stands 20 feet from the waterline to the top of the arch, and has an arch width of 39 feet with a deck 20 feet 9 inches wide. It was built as part of the Harrisburg to Lewistown section of the Harrisburg to Pittsburgh Turnpike, a road whose charter was granted by the Legislature in 1807 and whose western end was completed in 1818. The eastern section, begun with subscriptions in 1821, was finished in 1825. The bridge is regarded as the oldest single-span stone arch bridge in Central Pennsylvania. Its appearance was recorded in Currier and Ives lithographs of 1860, which helped make it widely known.","period_of_significance":null,"architect_builder":"Philip Diehl (builder)","architectural_style":null,"criteria":[],"status_note":"Repaired in 1930 and 1957 with no changes to its original appearance.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.448966-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/09000096.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/09000096/f23fe1112d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/09000096/f23fe1112d-1600.webp","licence":"CC BY-SA 3.0","author":"KATMAAN","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Oldarchbridge1.jpg\" rel=\"noopener\">KATMAAN</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:Oldarchbridge1.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996266","wikipedia":"https://en.wikipedia.org/wiki/Old_Stone_Arch_Bridge_(Lewistown,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q16983165"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/mifflin-county/old-stone-arch-bridge-09000096/"}
