The Virginia Department of Transportation (VDOT) has announced closures on Route 29 in Fairfax set to begin on May 2. These closures will take place on four non-consecutive weekends to facilitate the installation of a culvert as part of the widening project along Route 29. Both northbound and southbound traffic will be affected between Clifton Road/Stringfellow Road (Route 645) and Fairfax County Parkway (Route 286).
According to VDOT, the scheduled closures are on the following weekends: May 2-5, May 9-12, May 16-19, and May 30-June 2. There will be no closures over the Memorial Day weekend from May 23-26.
During these weekends, access to properties within the closure zone will be maintained; however, vehicles will not be able to proceed beyond the work zone. The installation of the culvert adjacent to 13100 Route 29 aims to carry Willow Springs Branch under the highway.
Through traffic will be rerouted via a detour that includes Clifton Road, Braddock Road (Route 620), and Fairfax County Parkway. Drivers are advised to follow all posted detour signs.
The improvements under the Route 29 widening project span from Union Mill Road to Buckleys Gate Drive. This project involves widening 1.5 miles of roadway from four lanes to six, improving sight distance by correcting vertical alignment, and constructing shared-use paths on both sides of the road. The project also aims to enhance connectivity to pedestrian and bicycle trails at the Fairfax County Parkway/West Ox Road interchange. Completion is anticipated in spring 2026.
Traffic updates and information on work zones or incidents are available at 511.vdot.virginia.gov, through the 511Virginia mobile app, or by calling 511 within Virginia.
