I can't remember if you live in the area. I live in Fairfax but not close to Seven Corners, but I used to drive through there to and from work in Falls Church (due to HOV restrictions) and it's just a mess, with all the traffic lights.
i graduated HS from falls church, about 2mi from the corners.
i know from the rashness of youthful experience that it was occasionally possible to get from jaguar drive to the belt in ~44sec, assuming the carbs were tuned ...
