It was constructed around 1871 by the Northern Central Division of the Pennsylvania Railroad.","why_significant":"The bridge is one of only two masonry arch bridges on the line that combine stone and brick in their construction. It displays a method of construction the nomination describes as uncommon on York County's railroads, where simple girder bridges are most often seen. It is one of four bridges remaining on the railway from the 1871 period and is in very good condition with its integrity retained.","narrative":"Built around 1871 by the Northern Central Division of the Pennsylvania Railroad, this masonry arch bridge carries the Northern Central Railway over a small runoff that feeds the south branch of the Codorus Creek near Larue in York County. The arch is formed of five header courses of brick, while the spandrels are cut stone, and the deck was filled with ground before the ties and rails were laid. It is one of only two bridges on the line that combine stone and brick in their construction, the other being Bridge 634 in Shrewsbury Township, which is much larger and crosses both a roadway and the Codorus Creek. The structure was built during a widening of the route to lay a second set of tracks between Baltimore and York, financed by the Pennsylvania Railroad. It is one of four bridges remaining from that period on the railway, and its masonry arch is unusual among the girder bridges common in York County. Freight and excursion trains still use it.","period_of_significance":"C. 1871 - 1942","architect_builder":"Northern Central Division of the Pennsylvania Railroad (builder)","architectural_style":null,"criteria":["C"],"status_note":"The bridge and the railroad are still in use today for the periodic movement of freight and train excursions.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.44508-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000549.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000549/c0519001f3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000549/c0519001f3-1600.webp","licence":"CC BY-SA 4.0","author":"Skabat169","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NCR_over_S_Branch_Codorus_Creek,_East_View.jpg\" rel=\"noopener\">Skabat169</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:NCR_over_S_Branch_Codorus_Creek,_East_View.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994103","wikipedia":"https://en.wikipedia.org/wiki/South_Road_Bridge,_Northern_Central_Railway","wikidata":"https://www.wikidata.org/wiki/Q7568340"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/york-county/south-road-bridge-northern-central-railway-95000549/"}
