Prince William transportation update: Minnieville/Old Bridge study, SPUI interchange moving into construction

Prince William County's transportation director told the board Tuesday that several high-profile road projects and safety efforts are advancing, and that some work has moved past design into construction preparation.

"We have just given notice to proceed to our contractor to be able to start this project," Rick Kenizales said of the Prince William Parkway and Minnieville Road interchange, a single-point urban interchange (SPUI) the county described as a seven-phase undertaking. Kenizales said initial steps include utility relocation and demolition, and that the contract schedules substantial completion in winter 2028 with final completion in spring 2028.

Kenizales also reviewed the countywide Comprehensive Traffic Safety Action Plan, begun in 2024 to push toward Vision Zero (urban areas) and Toward 0 (suburban/rural), and summarized public engagement results that prioritized crosswalks, pedestrian signals and multimodal facilities for the Minnieville/Old Bridge intersection study (roughly 600 survey contributions on PWC Works).

On another major project, he said the Route 234 Sudley Manor interchange is in procurement and staff is working with awarded funds and VDOT processes. "The project is $115,500,000 currently," Kenizales told the board, describing the aim of removing two existing signals to improve traffic flow.

Supervisors pressed about potential construction delays and nighttime work. Kenizales said the contractor anticipates using extended daytime hours and the contract allows night and weekend construction; he told the board VDOT will approve any reasonable night or weekend work necessary to keep the schedule.

Next steps: Transportation staff will bring further design contracts and procurement actions to the board as appropriate and continue outreach about schedule, maintenance-of-traffic plans and neighborhood impacts.
