Construction is underway on two major interchanges that will improve traffic along Virginia Route 7 in Loudoun County, Virginia. Dewberry provided engineering services for Loudoun County along both the Route 7 at Belmont Ridge Road (Route 659) interchange and the Ashburn Village Boulevard interchange.
Construction of the Route 659 interchange includes elimination of the signalized intersection and the realignment and vertical adjustment of approximately 1.4 miles of Route 659 to a four-lane roadway. Dewberry provided surveying and engineering design services for roadway, structure and bridge, hydraulic, stormwater management, traffic signal, and maintenance of traffic improvements. The $48.3 million project is anticipated to be complete in the fall of 2018.
At the Route 7/Ashburn Village Boulevard interchange, a new spread diamond interchange will replace the existing signalized intersection, providing congestion relief for motorists. Dewberry provided survey, preliminary engineering, traffic analysis, environmental permitting, floodplain analysis, utility coordination, bridge and roadway maintenance, stormwater management, signing, and traffic signal design as part of the Shirley Contracting Company, LLC design-build team. The project has primarily been funded by the One Loudoun development as a condition of the property’s rezoning approval.
