WBCM was the lead design engineer for the Design-Build construction of a roundabout at the intersection of Braddock Road (VA-620) and Pleasant Valley Road (VA-609). The existing four-way stop produced congestion and caused significant delays during peak travel times. The addition of a roundabout increased capacity to handle forecasted increases in traffic volume, while enhancing both vehicular and pedestrian safety. Curb ramps and crosswalks were added and linked to existing trail infrastructure where available.

WBCM provided extensive traffic, environmental, utility, permitting, and survey services that included documentation required by the National Environmental Policy Act (NEPA), right-of-way acquisitions, and coordination of utility relocations and adjustments. The maintenance of traffic plan required extensive analysis and design alternatives to maintain mobility during construction for an extremely congested intersection.
