If you've ever sat through multiple red lights at Minnieville Road and Prince William Parkway, relief is officially on the way — but the road to get there starts with some patience this summer.
On May 5, Prince William County broke ground on an $81 million interchange project at one of Woodbridge's most notoriously congested intersections. The new design will route Prince William Parkway through an underpass beneath Minnieville Road — replacing the current stoplight intersection with a grade-separated interchange similar to the one already in place near the western end of the Parkway. Construction is expected to wrap up in spring 2028.
Neabsco District Supervisor Victor Angry, whose district includes the project, called it a "game changer" at the groundbreaking ceremony.
"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."
— Supervisor Victor Angry, Prince William County
A whole new neighborhood is coming with it
The interchange isn't just a road project — it's the foundation for something much bigger. The Quartz District is a 145-acre mixed-use community at 13920 Minnieville Road, less than five minutes from I-95 and Potomac Mills, bringing more than 1,000 new homes to the area along with walkable retail and community amenities. Townhomes and garage condos are expected to start in the upper $400s, with a community pool, clubhouse, walking trails, open green space, and multiple playgrounds planned.
And the part Woodbridge residents may be most excited about the Quartz District will be anchored by Prince William County's first ever Whole Foods Market, along with 136,000 square feet of retail, restaurants, and shops. Retail and grocery are expected to open in 2028 once construction wraps up.
Think of it as a small walkable city being built from the ground up in eastern Prince William — and the new interchange is what makes it all possible.
How the Project Is Being Funded
The $81 million project is funded primarily by the Northern Virginia Transportation Authority, which is contributing $80 million. The remaining balance comes from Prince William County general funds and developer contributions from Buchanan Partners, the firm behind the Quartz District.
What Should Drivers Expect This Summer?
Before the intersection improves, it's going to get more complicated. Detours are expected to begin in July 2026, with certain left-turn movements restricted at the main intersection. A temporary detour road will be constructed along Elm Farm Road to provide an alternate connection between Minnieville Road and Prince William Parkway. Through traffic on both roads will continue, but drivers should expect adjusted travel patterns and delays.
If you don't have business in that corridor this summer, county officials are already advising: find an alternate route.
Construction is scheduled for completion in spring 2028.
