When you get off I-64 in Chesapeake VA, you actually take Rt 168, there is a toll rd called Chesapeake expressway that will save you 10 miles but toll rates double during summer months may to sept. If you don’t want to pay toll, the regular route is good, I drive it with my 32 ft RV with no problem, roads merge at end of toll road to continue to outer banks...good luck & enjoy your trip...
