PWC Works projects reflect our commitment of striving for exceptional customer service, maximizing operational efficiencies, increasing modernization, providing excellent service delivery, and collaborating with the community for a coordinated response that achieves the best possible outcomes for our residents and the overall wellbeing of the county.
What is the Route 234 and Sudley Manor Drive Interchange Project?
The Route 234 and Sudley Manor Drive Interchange Project is a major design-build effort to improve traffic flow and safety along Prince William Parkway. The project will reconstruct the intersection of Route 234 (Prince William Parkway) and Sudley Manor Drive and modify the nearby intersection at Wellington Road.
The interchange will be built as a single-point urban interchange (SPUI), enabling more efficient traffic flow through a single central signalized intersection. Prince William Parkway and Sudley Manor Drive will be grade-separated to maintain free-flow traffic along the parkway.
Currently, closely spaced signalized intersections at Sudley Manor Drive and Wellington Road, less than 1,400 feet apart, create significant congestion and delays. As part of the project, Wellington Road will be bridged over Prince William Parkway, and direct access from Wellington Road to the parkway will be shifted to the new interchange to improve operations and reduce conflicts.
Project Budget: $115.5 million
