Chas, I do with any bridge under 13' on the sides! Some times you can't but you can on the park way just be careful as it is a two lane road and very blind in spots. The parkway is beautful. if you like to drive on two lane roads start in VA and drive the skyline drive it starts in Front Royal and runs into the parkway about the intersection of I-64, real nice trip in the fall the colors. Good luck and have a good trip. There are a lot of campgrounds in that area both in VA & NC.
