CENTREVILLE – The right lane of southbound Route 29 between the Stringfellow Road/Clifton Road (Route 645) and Centreville Farms Road/Union Mill Road intersections will be closed from 10 p.m. Friday, Aug. 23 until 5 a.m. Monday, Aug. 26 for paving as part of the Route 29 Widening Project, according to the Virginia Department of Transportation.
Barring unforeseen circumstances, the right lane may reopen to traffic as soon as Saturday night, Aug. 24.
Drivers should expect delays and are advised to use alternate routes.
The work is occurring under a Fairfax County noise waiver and is part of the Route 29 Widening Project, which is making improvements along Route 29 between Union Mill Road and Buckleys Gate Drive to improve safety, traffic flow and bicyclist and pedestrian accessibility and connectivity. The improvements include:
- Reconstructing and widening 1.5 miles of roadway from four lanes to six
- Correcting vertical alignment to improve sight distance
- Adding shared-use paths on both sides of Route 29
- Providing connectivity to pedestrian/bicycle trails at the Fairfax County Parkway/West Ox Road interchange
The project is scheduled for completion in spring 2026.
