1966 Map of Thoroughfare Gap

About this map

Bull Run Mountains and Pond Mountains dominate this landscape, split by the narrow passage of Thoroughfare Gap. This natural corridor serves as the primary route for both the Southern railroad and Broad Run, creating a concentrated zone of transit and industry as evidenced by the historic Beverley Mill and numerous quarries along the ridge. To the east, the terrain transitions into the Piedmont lowlands, where established communities like Haymarket, Buckland, and Greenwich are connected by a growing network of roads and the visible presence of a major Pipeline. The southern portion of the map is defined by the Vint Hill Farms Station Military Reservation, while the surrounding countryside is dotted with community centers such as the Antioch-McCrae Sch and Oakrum Ch, reflecting the rural social fabric of mid-20th-century Prince William and Fauquier Counties.
