Prince William Parkway at Minnieville Road Interchange

Detours for the Prince William Parkway and Minnieville Road Interchange construction are anticipated to begin Friday, September 25, 2026.

What Remains Open

• All through‑traffic on Minnieville Road and Prince William Parkway
• All right‑turn movements in every direction
• Left turn from Prince William Parkway eastbound to Minnieville Road southbound

Left‑Turn Restrictions

• All other left‑turn movements are restricted at the intersection. Drivers who normally make these left turns will be directed to use the temporary detour route.

Temporary Detour Road

• A temporary detour road will be constructed on Elm Farm Road. This detour will provide an alternate connection between Minnieville Road and Prince William Parkway while left turns are restricted at the main intersection.

A ceremonial groundbreaking was held May 5, 2026, at the intersection of Prince William Parkway and Minnieville Road, marking the start of construction of a new interchange designed to enhance traffic flow and improve safety for drivers and pedestrians.

The $81 million project will route Prince William Parkway under Minnieville Road, increasing capacity at a key intersection and improving movement through an area that serves significant daily traffic. The new interchange will support future growth associated with the Quartz District, a planned mixed-use, walkable commercial center with surrounding residential development at the intersection’s northwest quadrant.

Neabsco District Supervisor and Board of County Supervisors Vice Chair Victor Angry, who emceed the groundbreaking ceremony for the project in his district, said the interchange will modernize a critical corridor while supporting continued development and improved mobility in eastern Prince William County.

“So for years, we've heard from the residents about development. And as we develop, we've heard that one thing that we haven't done well is infrastructure. The interchange behind you... was rated at a D rating, which is one of the worst in VDOT. But the upgrades that we're doing... will take it from a D rating to a B rating. And at the same time of doing this project, it ties very much closely to the Quartz project that you see behind us, as well,” said Angry.

“This corridor and this end of the county is truly changing,” Angry said. “This literally is a game changer for the county and how we develop going forward.”

Prince William County Chair At-Large Deshundra Jefferson said the project represents an important step in preparing the area to support the growth and opportunity the Quartz District will bring.

“This interchange is truly the foundation that makes the Quartz District possible,” said Jefferson. “The interchange will reduce congestion, improve traffic flow and increase safety for drivers and pedestrians alike. Projects like this continue to exemplify why we are a vibrant, growing and diverse community.”

County Executive Chris Shorter said the corridor has long been a critical artery for commuters, residents and businesses, bringing with it challenges including congestion and limitations that have impacted quality of life and economic opportunity.

“This project is our response. It is about reducing congestion and improving travel times for families. It is about enhancing safety for drivers, pedestrians and cyclists alike. And it is about supporting continued growth in a way that is smart, that is strategic and that is aligned with our long-term vision. This investment reflects the priorities outlined in the county's strategic plan, particularly around mobility, economic growth and building a community that invests in quality of life for everyone,” said Shorter.

The project is funded through Northern Virginia Transportation Authority 30 percent funds, proffers and local funding sources.

Northern Virginia Transportation Authority Board Chair Phyllis Randall emphasized the regional collaboration required to deliver projects of this scale.

“When we talk about regional collaboration, and when NVTA says, ‘We put money in for congestion relief relative to cost,’ what we know is, this corridor in this area is not just important to people who are going to be in Prince William County, but all the entire region, which is why it was important for NVTA to put money into this effort,” Randall said.

Lane Construction Corporation was awarded the construction contract and started work on the project in early March after Rinker Design Associates concluded design work. Project completion is anticipated in spring 2028.
