Thompson.","why_significant":"The nomination argues the bridge is architecturally significant as one of three intact examples of rural vernacular stone arch vehicular bridges in Shandaken and an extremely rare survivor in Ulster County. It shows traditional masonry bridge construction techniques and retains a high degree of integrity.","narrative":"Carrying Elm Street across Alton Creek in the hamlet of Pine Hill, this small stone arch bridge was built around 1900 by local mason Matthew G. Thompson. Town board minutes from December 1900 record the hiring of M.G. Thompson for $208 to build one of the stone bridges at Pine Hill. The structure is solid masonry with a single round arch of locally quarried stone, about 12 feet between abutments and roughly 6 feet from the creek surface to the top of the arch. Rough-dressed voussoirs and a keystone form the arch, while the spandrel walls use random coursed stone and the abutments use larger, carefully dressed stones. It is one of three surviving stone arch bridges in Pine Hill, and it is considered a rare Ulster County example of a craft that has largely died out. It remains substantially intact and keeps its natural setting, which led to its listing for architectural significance.","period_of_significance":"ca.1900","architect_builder":"Thompson, Matthew G., Mason","architectural_style":"OTHER (rural vernacular stone arch bridge)","criteria":["C"],"status_note":"Described as completely intact from its original construction, with a high degree of integrity and a preserved natural setting; owned by the Town of Shandaken and still used as a bridge.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.027471-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/96001437.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96001437/2d4f7d4b56-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96001437/2d4f7d4b56-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Elm_Street_Stone_Arch_Bridge,_Pine_Hill,_NY.jpg\" rel=\"noopener\">Daniel Case</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:Elm_Street_Stone_Arch_Bridge,_Pine_Hill,_NY.jpg"},"district":{"nrhp_refnum":"12000513","name":"Pine Hill Historic District","url":"https://nationalhistoricalregister.com/districts/new-york/pine-hill-historic-district-12000513/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322614","wikipedia":"https://en.wikipedia.org/wiki/Elm_Street_Stone_Arch_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5366342"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ulster-county/elm-street-stone-arch-bridge-96001437/"}
