The Dulles Greenway is a toll road so it isn't necessarily part of the trunk network, and there also isn't really anything of significance at the junction of LCP and the Greenway. Old Ox Road at the least connects towards IAD, Sterling Herndon, and Reston, but I think that the whole thing, including my changes, should be reverted wholly to primary. I feel like someday, if there is a more direct highway extension between Gainesville and South Riding as has been proposed for a while now, I could see the reason for a trunk route within this vicinity, but for now it would be best for these roads to remain primary since they don't serve much of the purpose that they were intended to yet.
