Local bridge builder Alvah Hopson built it using a Burr truss.","why_significant":"It is the only survivor of seven covered bridges once present in the town of Salisbury and the only example of its type in its region of the state. Only twenty-five of more than 250 nineteenth-century covered bridges in New York still exist. It represents a vernacular building tradition that continued despite growing industrialization.","narrative":"This 42-foot wooden covered bridge crosses Spruce Creek on Fairview Road in Salisbury Center, near an old mill site and spillway and beside a picnic area. Alvah Hopson, a local bridge builder, completed it in 1875 using the Burr truss, a system combining a flat truss with two timber arch ribs on each side of the roadway. Wood pins hold the frame together, and the arches rest on stone and concrete abutments. A sign over the north portal warns of a one-dollar fine for crossing faster than a walk. The bridge was listed because it is the sole survivor of seven such bridges once in the town of Salisbury and the only example of its type in its region of New York. Only twenty-five of more than 250 covered bridges built in the state in the nineteenth century still exist. Today it carries light traffic, limited to vehicles under two tons.","period_of_significance":"1875","architect_builder":"Alvah Hopson, local bridge builder","architectural_style":"Burr truss (arch-and-truss) covered bridge","criteria":[],"status_note":"Condition listed as fair; open to vehicles under two tons with minimal traffic. Alterations include a metal roof covering, replaced siding and flooring boards, and a concrete abutment from 1968.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.673618-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/72000848.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000848/6f17f7bed9-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000848/6f17f7bed9-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Albany, New York, United States","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Salisbury_Covered_Bridge_May_08.jpg\" rel=\"noopener\">Doug Kerr from Albany, New York, United States</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Salisbury_Covered_Bridge_May_08.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318190","wikipedia":"https://en.wikipedia.org/wiki/Salisbury_Center_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7404747"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/herkimer-county/salisbury-center-covered-bridge-72000848/"}
