It was built in 1931 by the Massachusetts Department of Public Works.","why_significant":"The parkway was built to the design standards of the Metropolitan Park System's river and connecting parkways. It follows the curves of the Neponset River and has granite curbing, a turf median and an allee of oak trees. It is significant at the state level for community planning and development, engineering, landscape architecture and transportation.","narrative":"Truman Parkway is a nearly two-mile road linking Brush Hill Road in Milton with Neponset Valley Parkway in Boston's Hyde Park neighborhood. Built in 1931 as Truman Highway by the Massachusetts Department of Public Works, it follows the gentle curves of the Neponset River and ends inside the Neponset River Reservation. Two lanes run in each direction, separated by a turf median edged in granite and lined with evenly spaced oak trees. A single-arch granite bridge carries it over the river. Although the state parks agency did not take over the road from the City of Boston until 1971, its design closely matches parkways built by the Metropolitan District Commission. The parkway is considered significant at the state level for its role in community planning, engineering, landscape architecture and transportation. Its period of significance runs from 1931 to 1956, and it retains integrity of location, design, setting, materials and workmanship.","period_of_significance":"1931-1956","architect_builder":"Massachusetts Dept. of Public Works","architectural_style":null,"criteria":["A","C"],"status_note":"Still in use as a four-lane divided roadway owned by the Commonwealth of Massachusetts, Department of Conservation and Recreation (DCR).","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.778914-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/93/7927/63792793/content/electronic-records/rg-079/NPS_MA/04001430.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04001430/d392c34c91-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04001430/d392c34c91-1600.webp","licence":"CC BY-SA 3.0","author":"Jameslwoodward","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Truman_Parkway_Boston_MA.jpg\" rel=\"noopener\">Jameslwoodward</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:Truman_Parkway_Boston_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63792793","wikipedia":"https://en.wikipedia.org/wiki/Truman_Parkway","wikidata":"https://www.wikidata.org/wiki/Q1156354"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/suffolk-county/truman-parkway-metropolitan-park-system-of-greater-boston-04001430/"}
