Its gable roof and full vertical planked side walls are noted as distinguishing features, and its portals are said to be similar in style to those of the Trostletown and Shaffer's bridges.","narrative":"Built in 1879 over the Raystown Branch of the Juniata River in Allegheny Township, Somerset County, the New Baltimore Bridge is a covered timber bridge carrying a road across the stream near New Baltimore Borough. It uses a queenpost truss, a common form for covered bridges of its era. Its gable roof and full vertical planked side walls give it a closed, enclosed appearance, and its portals are similar in style to those of the Trostletown and Shaffer's bridges, linking it to a group of covered bridges in the county. The deck is timber, the roadway is 12 feet wide, and the clearance is 11 feet. The bridge carries a posted load limit of 3 tons. At the time of documentation, it was in good condition, though the northwest corner wing wall was pulling away from the approach. The bridge was documented as part of a multiple-property group of ten covered bridges in Somerset County, and it is recognized for its construction as a surviving example of regional timber bridge building.","period_of_significance":null,"architect_builder":null,"architectural_style":"Queenpost truss","criteria":[],"status_note":"Condition is given as good, except that the northwest corner wing wall is pulling away from the bridge approach.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.431772-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003630.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003630/3ffa80c295-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003630/3ffa80c295-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NEW_BALTIMORE_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:NEW_BALTIMORE_COVERED_BRIDGE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993867","wikipedia":"https://en.wikipedia.org/wiki/New_Baltimore_Bridge","wikidata":"https://www.wikidata.org/wiki/Q7005420"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/somerset-county/new-baltimore-bridge-80003630/"}
