 In a loop and out a loop in Virginia between the toll road and the GW Parkway, the right lane is blocked for the work zone there. If you're traveling otherwise along the Fairfax County Parkway northbound near Burke Center Parkway, the left lane gets you by that scheduled work zone. Traveling I-95 southbound after Dumfries, that's where the work continues to block the right lane. Northbound I-95 coming past the Dale City Truck Scales, the work in the right lane, your delay is northbound.
