1989 Map of Thoroughfare Gap

About this map

The Bull Run Mountains and Pond Mountains dominate the western horizon of this survey, creating a natural barrier pierced by the strategic Thoroughfare Gap. This passage has long dictated the movement of commerce and people, anchoring settlements like Thoroughfare and Broad Run along the rail line. To the east, the landscape transitions from the steep slopes of High Point Mtn to the rolling terrain of the Fauquier and Prince William county line, where the suburban growth of Haymarket begins to emerge near Interchange 40.
