Beginning Friday, motorists traveling through the busy intersection of Prince William Parkway and Minnieville Road will encounter temporary left‑turn restrictions while the county moves forward with the $81 million Prince William Parkway at Minnieville Road Interchange Project. The work, part of a larger effort to replace the existing signalized junction with a single‑point urban interchange (SPUI), is designed to improve traffic flow, increase capacity and support future growth in the area.
What drivers will see
Most left‑turn movements at the intersection will be closed during construction, though through traffic and all right‑turn movements will remain open in both directions. The specific left‑turn from northbound Prince William Parkway (heading toward Old Bridge Road) to westbound Minnieville Road (toward Dale Boulevard) will stay open to minimize disruption for local commuters.
Drivers affected by the restrictions will be directed to posted detour signs. Motorists are urged to allow extra travel time, follow the detour routes carefully and exercise caution while traveling through the work zone. Detailed maps of the new traffic patterns are available on the county’s website.
Project details and timeline
The interchange will place Prince William Parkway beneath Minnieville Road, eliminating the current signal‑controlled crossing. The SPUI design is a proven solution for high‑volume corridors, allowing smoother merging and turning movements while reducing the likelihood of rear‑end collisions.
Construction is scheduled to continue through 2027, with a target completion date in spring 2028. The project is funded through a combination of state and local transportation funds, reflecting the county’s commitment to maintaining safe and efficient roadways for residents and businesses.
Supporting future development
One of the key reasons for the interchange is to accommodate anticipated traffic from the nearby Quartz District. The 145‑acre commercial center, planned for the northwest corner of the intersection, will feature more than 1,000 housing units along with a variety of retail and service businesses, including the county’s first Whole Foods market.
County officials say the new interchange will help prevent congestion as the Quartz District and surrounding neighborhoods grow, ensuring that residents can travel quickly to work, school and shopping destinations.
Community response
Local residents have expressed mixed feelings about the temporary inconvenience. While some commuters are concerned about added travel time, many recognize the long‑term benefits of a modern interchange that will reduce daily delays once completed. The county’s transportation department has scheduled regular updates on progress and will adjust detour routes as needed to keep traffic moving smoothly.
For the latest information, including real‑time traffic alerts and detour maps, drivers should visit the Prince William County Department of Public Works website or follow the agency’s social‑media channels.
