It was built in 1886 by Jeremiah Cunningham.","why_significant":"The bridge is argued to be a representative example of rural vernacular stone bridge design and to reflect the role of roads and bridges in the development of the town of Durham. It is one of eight surviving stone arch bridges in the town built by Jeremiah Cunningham while he served as bridge commissioner. Despite an eight-foot widening and concrete abutment reinforcement, it retains enough integrity to show its design and craftsmanship.","narrative":"Carrying Shady Glen Road over a small tributary of Catskill Creek, this limestone arch bridge sits in a rural part of Durham, roughly midway between the hamlets of Durham Centre and Cornwallville. Built in the spring of 1886, it is a single-span structure of dry-laid local limestone with a round arch spanning fourteen feet. Jeremiah Cunningham built it soon after becoming the town's highway commissioner, a post he held for ten years while building thirteen stone arch bridges. The crossing lay on the main route between the two hamlets and gave access to an adjacent mill, and it may also have served nearby tourist guest houses. In the late twentieth century the west end was widened by eight feet using a steel culvert, fill and stone facing, and the abutments received concrete footings. The original eighteen-inch-thick arch survives behind the addition. The bridge is recognized for its craftsmanship and its place in local transportation history.","period_of_significance":"1886","architect_builder":"Jeremiah Cunningham, builder","architectural_style":"no style","criteria":["A"],"status_note":"Still in road use; widened by eight feet in the late twentieth century, with the original arch intact behind the addition.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:54.0317-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/07001368.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07001368/567d61509b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07001368/567d61509b-1600.webp","licence":"CC BY-SA 4.0","author":"RobertDrake2015","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Shady_Glen_Road_Stone_Arch_Bridge_11-10-2016.jpg\" rel=\"noopener\">RobertDrake2015</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:Shady_Glen_Road_Stone_Arch_Bridge_11-10-2016.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318045","wikipedia":"https://en.wikipedia.org/wiki/Shady_Glen_Road_Stone_Arch_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7460893"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/greene-county/shady-glen-road-stone-arch-bridge-07001368/"}
