This paved auto/cycle route is windy and hilly with one short avoidable section of gravel between RP 12-13. There are several noted sections of severe switchbacks which require attention but will thrill the adventuresome driver. There are no tollways and only a couple miles of interstate.
A caution: There is significant distance between gas and food in some parts of this drive. Service needs of both people and machines should be monitored and addressed closely.
