Northbound and southbound Stringfellow Road (Route 645) between Route 29 and Centreville Farms Road will be closed to through traffic Saturday, Aug. 17 from 7 a.m. to 5 p.m. for paving, according to the Virginia Department of Transportation.
Local traffic will still be able to use Stringfellow Road between Centreville Farms Road and Autumn Willow Drive; however, Stringfellow Road will be closed to all traffic in both directions between Autumn Willow Drive and Route 29.
Through traffic will be detoured via Route 29 and Centreville Farms Road back to Stringfellow Road. Drivers are asked to follow detour signs.
The work 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:
• Widening 1.5 miles of roadway from four lanes to six
• Improving 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.
