2022 Map of Thoroughfare Gap

About this map

Thoroughfare Gap serves as the focal point where the Bull Run Mountains meet the historical transportation corridor of Northern Virginia. This 2022 survey documents the persistent rural character of western Prince William County even as residential growth extends from Gainesville and Haymarket. The landscape is densely populated with family heritage sites, including the Harrison-Norvill Cem, Delaplane Family Cem, and Chapman Family Cem, offering a detailed record for genealogical research. The historic Beverley Mill stands near the gap, a landmark of 18th-century industry at the edge of Broad Run. Settlements like Buckland and Antioch remain anchored by local institutions such as the Oakrum Baptist Church and Saint Paul's Episcopal Church. Natural water features, including Lake Manassas and Lake Brittle, define the southern reaches of the quadrangle while the Norfolk Southern line follows the traditional path through the mountains.
