Drivers on Route 29 in Fairfax, Virginia, can expect weekday single-lane closures between Union Mill Road/Centreville Farms Drive and Summit Drive/Buckleys Gate Drive for widening project work. The closures are scheduled from May 4 to May 8, with another set from May 11 to May 11. The work includes 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, and providing connectivity to pedestrian and bicycle trails at the Fairfax County Parkway/West Ox Road interchange. The project is expected to be completed this summer.
