It was built 1813-1827 by the Georgetown & Leesburg Turnpike Company and the Falls Bridge Turnpike Company.","why_significant":"The nomination argues the road was an essential link between the Federal City and the west, and an important part of Virginia's turnpike history and the early automobile era in Northern Virginia. It also embodies Federal-era engineered road construction, using a modified Tresaguet layered-stone method. It is described as the last of four major nineteenth-century Arlington and Fairfax turnpikes to keep its design integrity and historic character.","narrative":"Georgetown Pike is a 14.4-mile road leading from Chain Bridge on the Potomac River, through Arlington and Fairfax Counties, to the Leesburg Pike near Dranesville. Two private turnpike companies built it between 1813 and 1827 to connect Georgetown markets with farms and mills around Leesburg. Workers using hand tools and horse-drawn equipment laid a crowned roadbed of large fitted stones topped with broken stone, about 18 inches deep at the center, with drainage ditches on both sides. This method adapted the French Tresaguet system to American terrain. The roadbed survived flooding, Civil War damage and neglect, and was repaired and opened to automobiles in 1923 by a third company. Virginia took over the road in 1934. Surviving features include a stone retaining wall at Pimmit Run and a stone and brick bridge over Bull Neck Run. The road is considered the last of four major local turnpikes to keep its original design and scenic character.","period_of_significance":"1813-1934","architect_builder":"Georgetown & Leesburg Turnpike Company / Falls Bridge Turnpike Company","architectural_style":"OTHER / Turnpike","criteria":["A","C"],"status_note":"Still in use as a road; maintained by the Virginia Department of Transportation, with part of the route designated Virginia's first Scenic and Historic Byway in 1973.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:03.544406-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/38/6796/41679638/content/electronic-records/rg-079/NPS_VA/12000537.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/12000537/30faa49555-800.webp","url_1600":"https://nationalhistoricalregister.com/media/12000537/30faa49555-1600.webp","licence":"CC BY-SA 4.0","author":"Famartin","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:2016-10-27_11_23_37_View_east_along_Virginia_State_Route_193_(Georgetown_Pike)_at_Seneca_Road_(Virginia_State_Secondary_Route_602)_in_Great_Falls,_Fairfax_County,_Virginia.jpg\" rel=\"noopener\">Famartin</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:2016-10-27_11_23_37_View_east_along_Virginia_State_Route_193_(Georgetown_Pike)_at_Seneca_Road_(Virginia_State_Secondary_Route_602)_in_Great_Falls,_Fairfax_County,_Virginia.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41679638","wikipedia":"https://en.wikipedia.org/wiki/Virginia_State_Route_193","wikidata":"https://www.wikidata.org/wiki/Q2508009"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/arlington-county/georgetown-pike-12000537/"}
