Prince William County Route 641 (PWC 641) is a local road. It is a local road used mainly for commuter traffic trying to get between Lake Ridge and places westward. It is designated from the light where Prince William Parkway turns westward and Touchstone Circle to Gordon Blvd (VA 123). It is 4 lanes wide from Prince William Parkway to Minnieville Road and 6 lanes wide from Minnieville Road to VA 123. As of now, there are currently stoplights at the following intersections along this road:
There is some history behind this road. But it is a little complicated and it will be added in my next update. By then, I am hoping to get some pictures from Microsoft's Terraserver website (or at least give links) to explain things. In the mean time, I encourage you to email me if you have something to add to this.
