It was built around 1858.","why_significant":"The bridge is argued to be a rare surviving mid-nineteenth century engineering and transportation structure in Rhinebeck. It is one of only two extant stone arch bridges of its type and period in the town, the other being the Salisbury Turnpike Bridge. It reflects vernacular fieldstone masonry traditions of the mid-Hudson Valley and has continued in its original use.","narrative":"Carrying Miller (Pilgrim's Progress) Road over the Landsman Kill in a wooded, undeveloped part of Rhinebeck, this triple-arched bridge was built of mortared random fieldstone around 1858. Its three barrel arches use dressed cut-stone voussoirs without keystones, a result of the traditional method of supporting the arches on timber falsework until the mortar set. Bluestone coping and a steel post-and-pipe railing run along the roadway. The structure measures 94 feet long and 18 feet 1 inch wide. Much of its stone is said to have come from the Schuyler grist mill, demolished in 1858, and the bridge served the Salisbury Turnpike link between eastern Dutchess County farmland and Rhinebeck village. Even though timber and iron were common bridge materials by the 1850s, builders here followed Hudson Valley stonework practices dating to the early eighteenth century. It is one of two surviving bridges of its type and period in the town, and it is still used by vehicles.","period_of_significance":null,"architect_builder":null,"architectural_style":"Vernacular triple-arch stone masonry bridge","criteria":[],"status_note":"Condition is rated fair; the bridge remains in use as a vehicular bridge and is on its original site.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.879808-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/87001102.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87001102/b31184ade4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87001102/b31184ade4-1600.webp","licence":"CC BY-SA 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pilgrims_Progress_Road_Bridge,_Rhinebeck_NY.jpg\" rel=\"noopener\">John Phelan</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:Pilgrims_Progress_Road_Bridge,_Rhinebeck_NY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75312725","wikipedia":"https://en.wikipedia.org/wiki/Pilgrim%27s_Progress_Road_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7193911"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/dutchess-county/pilgrims-progress-road-bridge-87001102/"}
