Shurcliff. The form finds them significant at the state level for landscape architecture, engineering, conservation, recreation, transportation and community planning. Hemlock Road follows a right of way dating to the 1600s.","narrative":"Four paved roads totaling 4.42 miles make up this parkway district inside Breakheart Reservation, a 640-acre wooded park of rocky outcrops, two lakes and a stretch of the Saugus River in Saugus and Wakefield. Forest Street is a short divided parkway that connects the park to Lynn Fells Parkway, while Pine Tops, Elm and Hemlock Roads are single-lane internal roads now used mainly by walkers and joggers. Contributing features include fieldstone entry gate piers, a system of historic culverts, and wooden and steel roadside barriers. Hemlock Road follows a right of way dating to the 1600s. The Metropolitan District Commission acquired the former hunting preserve in 1934, and Civilian Conservation Corps workers built the roads under a design credited to landscape architect Arthur A. Shurcliff. The roads were recognized for their landscape architecture, engineering and recreational role, with a period of significance from 1934 to 1956.","period_of_significance":"1934-1956","architect_builder":"Charles Eliot, Olmsted Brothers, Arthur Shurcliff, Civilian Conservation Corps (CCC)","architectural_style":null,"criteria":["A","C"],"status_note":"Forest Street is the only parkway open to vehicles; Pine Tops, Elm and Hemlock Roads are closed to public vehicles and used by pedestrians, joggers, and emergency and maintenance vehicles.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.080392-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/66/7902/63790266/content/electronic-records/rg-079/NPS_MA/03000748.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000748/b34f5c3ef3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000748/b34f5c3ef3-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:BreakheartReservationLowerPondView.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:BreakheartReservationLowerPondView.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790266","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q108906420"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/breakheart-reservation-parkways-metropolitan-park-system-of-greater-boston-03000748/"}
