It was built in 1885 by the Berlin Iron Bridge Company.","why_significant":"It is the oldest surviving lenticular pony truss in Massachusetts and one of only ten remaining lenticular truss highway bridges in the state. It uses William O. Douglas's patented floor-line tension chord, a feature found on only this one of five surviving lenticular pony trusses in the state inventory. It represents a type of iron truss once common in western Massachusetts.","narrative":"Carrying Golden Hill Road across the Housatonic River just northeast of downtown Lee, this 81-foot iron bridge is a lenticular pony truss, a design locals call a \"pumpkin seed\" for its curved outline. The town of Lee bought it in 1885 from the Berlin Iron Bridge Company of Connecticut, replacing a worn wooden span, for a bid of $943. The bridge opened on July 7, 1885, after less than two months of work, and the total cost reached $1,166.01. It rests on marble abutments quarried in Lee. Its wrought-iron trusses include a tension floor-line chord based on William O. Douglas's 1885 patent, a feature unique among the five surviving lenticular pony trusses in the state inventory. It is the oldest lenticular pony truss left in Massachusetts and one of ten lenticular highway truss bridges remaining there. It was listed for its engineering and design significance at the local level, and it still carries traffic.","period_of_significance":"1885","architect_builder":"Berlin Iron Bridge Co.","architectural_style":"No Style","criteria":["C"],"status_note":"Described as showing few signs of alteration and in fair condition, and as one of the few lenticular truss bridges still in active use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:05.111431-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/74/7943/63794374/content/electronic-records/rg-079/NPS_MA/93001592.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/93001592/289dab479f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/93001592/289dab479f-1600.webp","licence":"CC BY-SA 3.0","author":"KevinSprague","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:GoldenHill_BridgeDSC_7656.jpg\" rel=\"noopener\">KevinSprague</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:GoldenHill_BridgeDSC_7656.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63794374","wikipedia":"https://en.wikipedia.org/wiki/Golden_Hill_Bridge","wikidata":"https://www.wikidata.org/wiki/Q5579554"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/berkshire-county/golden-hill-bridge-93001592/"}
