 If you're southbound on 28, it's about a four-mile backup coming out of Sterling through Herndon with only one right lane open across from the crash scene at McLaren Road. The end run, taking 606 on the other side of Dulles Airport, maybe Fairfax County Parkway where traffic will be heavier this afternoon, but traffic on the County Parkway is moving well parallel to that part of Route 28. However, there is a new crash in Fairfax Station, and that's slowing the pace both ways on 286 near Burke Center Parkway.
