The document gives no builder or construction year for this bridge.","why_significant":"The nomination argues the bridge is a surviving example of a type of construction common in its period and now increasingly rare. It is described as significant for its association with the history of transportation in Pennsylvania and as illustrative of rural bridge network development in Juniata and Snyder counties.","narrative":"Near Dimmsville in Juniata County, Pennsylvania, the Dimmsville Covered Bridge carries a road across Cocolamus Creek. It is a Burr truss structure with a 100-foot end post length and a road surface about 15 feet wide. The bridge has vertical siding, rectangular windows at eave level, a square window at midpoint, a gable roof, and cut stone abutments. Its construction is typical of the covered bridges built in rural Pennsylvania during the late nineteenth and early twentieth centuries, a type now increasingly rare. The bridge is regarded as significant for its link to the history of transportation in Pennsylvania and for illustrating how rural bridge networks developed in Juniata and Snyder counties. It was recorded in excellent condition at the time of nomination and is one of a group of covered bridges documented together in the two counties.","period_of_significance":null,"architect_builder":null,"architectural_style":"Burr truss covered bridge","criteria":["A","C"],"status_note":"Condition recorded as excellent.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.279952-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002245.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002245/648aa4de65-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002245/648aa4de65-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:DIMMSVILLE_COVERED_BRIDGE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:DIMMSVILLE_COVERED_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993101","wikipedia":"https://en.wikipedia.org/wiki/Dimmsville_Covered_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5277722"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/juniata-county/dimmsville-covered-bridge-79002245/"}
