It also contributes to the rural setting both visually and historically. It was nominated within a group of covered bridges in Washington County under the theme of transportation.","narrative":"Eagleville Covered Bridge carries Eagleville Road across the Batten Kill in the hamlet of Eagleville, Washington County, New York. Built in 1858 by Ephraim Clapp, it is a single wooden span about 100 feet long with a 16-foot roadway width, and it is covered with vertical board siding. Its structure is a pin-connected Town lattice plank truss, a design patented by Ithiel Town in 1820, with paired timber top and bottom chords and diagonal planks of three by ten inches. The bridge rests on concrete abutments. It remains in its original use as a highway bridge, owned by Washington County, though a five-ton limit applies and oversized loads are noted as a threat. The inventory describes it as an important survival that adds to the rural setting both visually and historically. It was recognized as one of several covered bridges in Washington County, with significance tied to transportation and early timber bridge engineering.","period_of_significance":null,"architect_builder":"Ithiel Town patent truss (1820); builder Ephraim Clapp","architectural_style":"Town plank lattice truss covered bridge","criteria":[],"status_note":"Still used as a highway bridge, with a 5-ton weight limit; oversized loads are listed as a threat.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.53111-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/78003458.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78003458/e8d01218dc-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78003458/e8d01218dc-1600.webp","licence":"CC BY 3.0","author":"David Broad","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Covered_Bridges_of_New_England_-_Shustan_NY_-_panoramio.jpg\" rel=\"noopener\">David Broad</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Covered_Bridges_of_New_England_-_Shustan_NY_-_panoramio.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315437","wikipedia":"https://en.wikipedia.org/wiki/Eagleville_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5325409"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/washington-county/eagleville-covered-bridge-78003458/"}
