The Fairfax County Department of Transportation (FCDOT) will begin construction to widen Route 28 from four to six lanes between the bridge over Bull Run (south of Compton Road) and the interchange at Route 29 in Centreville on or about March 1, 2021.

The first stage of construction will include paving and strengthening portions of the existing shoulders along the entire length of the project, specifically:

• In the southern portion of the project, between the bridge over Bull Run and the intersection of Route 28 and Old Mill Road/Green Trails Boulevard, work will be completed along the outside (right) shoulder in the southbound direction and along the median (left) shoulder in the northbound direction.
• In the northern portion of the project, between the intersection of Route 28 and Old Mill Road/Green Trails Boulevard and the interchange at Route 29, work will be completed on the outside (right) in both the southbound and northbound directions.

In future construction stages, traffic will be shifted onto the newly paved shoulders so that construction activities can be completed with minimal impact to traffic flow during peak travel periods. 

Beginning the week of Feb. 15, the contractor will begin installing construction signs and message boards in advance of construction activities.

What To Expect

Drivers should expect delays and be on the lookout for temporary lane closures during off peak hours for both the advance construction sign installation and shoulder paving and strengthening work. Temporary lane closures on Route 28 will be restricted from 9:30 a.m. to 3:00 p.m. Monday through Thursday, and 9:30 a.m. to 2 p.m. on Fridays. No lane closures will be allowed during peak travel periods and holidays. Weekend and nighttime work activities are not currently planned for this stage of construction, but are anticipated in future stages. All work is weather dependent and will be reschedule if inclement conditions occur.
