It was constructed in 1874 and is one of ten stone bridges in this nomination built in Montgomery County.","why_significant":"The bridge is described as a typical nineteenth-century stone highway bridge with two short arch spans flanked by long approach walls. A small built-in recession sets the arch spans apart from the rest of the body, a feature the nomination says appears peculiar to Montgomery County, where five stone arch bridges share it. As a group, the county bridges illustrate the continuing tradition of stone masonry bridge construction in Pennsylvania.","narrative":"Built in 1874, this stone highway bridge carries a local road across West Branch Neshaminy Creek in Hatfield Township, Montgomery County. It has two arch spans, each about 20 feet long, flanked by long approach walls of masonry. The arch spans are set off from the body of the bridge by a shallow built-in recession, which creates a rectangular outline across both arch crowns. This arrangement is regarded as a feature peculiar to Montgomery County, where five stone arch bridges share it. The bridge is one of ten stone bridges in the county that were nominated as a group, with construction dates ranging from 1789 to 1910. Together they show the continuation of stone masonry bridge building in Pennsylvania over more than a century. The bridge's engineering design and its place within this regional tradition are the basis for its listing.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"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 17:11:36.186878-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/88000861.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000861/364022dbb3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000861/364022dbb3-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Bridge_in_Hatfield_Township_02.JPG\" rel=\"noopener\">Shuvaev</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:Bridge_in_Hatfield_Township_02.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993396","wikipedia":"https://en.wikipedia.org/wiki/Bridge_in_Hatfield_Township","wikidata":"https://www.wikidata.org/wiki/Q4966359"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/bridge-in-hatfield-township-88000861/"}
