Route 7 Widening
The proposed widening of Route 7 (Leesburg Pike) requires the provision of an additional lane on each side of the roadway for a total of six 12-ft. lanes with curb and gutters, divided by a 16-ft. raised grass median, with 12-ft. turn lanes at various intersections, a 10-ft. multipurpose asphalt trail on each side, and a 120-ft. minimum right-of-way. The limits of the project are from the intersection of Route 7 with Rolling Hill Drive to the intersection of Route 7 with Tyco Toad, for a total distance of 8.2 miles.
