In time for the morning rush on Thursday, Nov. 15, the Virginia Department of Transportation will shift traffic onto the new Fairfax County Parkway (Route 286) bridges over Fair Lakes Parkway and Monument Drive. The new bridge spans from south of Fair Lakes Parkway to north of Monument Drive.
With the new overpass, motorists wonâ€™t encounter a traffic signal for the five-mile stretch between Popes Head Road and Route 50.
The new interchange removes one of the busiest — and most congested — intersections in Fairfax County, one that’s been a major source of congestion at all hours.
During the overnight traffic switch, the Fairfax County Parkway will be reduced to one lane in each direction; Fair Lakes Parkway traffic will be detoured onto Fair Lakes Circle; and the ramp from westbound I-66 to northbound Fairfax County Parkway will be closed and traffic will follow a detour.
The $69 million interchange project will be completed next spring.
