It is one of the covered bridges listed as a thematic group in Washington and Greene Counties.","why_significant":"The nomination presents the bridge as an important example of vernacular wood bridge technology, embodying the characteristics of covered bridge construction. It notes that covered bridges were once a common bridge type in Pennsylvania and that these surviving examples in the two rural counties illustrate the type's construction and the simplicity of its truss designs and local design features.","narrative":"Built in 1889 by Bailey Brothers, the Bailey Covered Bridge crosses Ten Mile Creek in Amwell Township, Washington County, near the village of Prosperity. It is a Burr truss structure with a span of 66 feet and a road surface 15 feet wide. Its cut stone abutments are still in place, while steel beams and a mid-stream concrete pier now give additional support to the span. The bridge has vertical board siding, a tin-covered gable roof, and two windows on each side wall. It is one of a group of covered bridges in Washington and Greene Counties that were gathered in a single listing. The nomination regards these bridges as representative examples of wood bridge building in rural Pennsylvania, where covered bridges were once a common type. Its simple truss design and local construction features are cited as the reasons for its recognition. The bridge is in good condition and remains a surviving example of this regional tradition.","period_of_significance":null,"architect_builder":"Bailey Brothers (builder)","architectural_style":null,"criteria":["C"],"status_note":"Condition given as good; the bridge has steel beams and a mid-stream concrete pier supporting the cut stone abutments and span.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.330805-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002355.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002355/6134a781fb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002355/6134a781fb-1600.webp","licence":"CC BY 2.0","author":"Kathy","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Bailey_Covered_Bridge.jpg\" rel=\"noopener\">Kathy</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Bailey_Covered_Bridge.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993995","wikipedia":"https://en.wikipedia.org/wiki/Bailey_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q4848342"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/bailey-covered-bridge-79002355/"}
