Corrected heading levels
Follow the guidelines for your area when naming the exits from the highway. In the [[Road_Naming_(USA)#Exit_ramps_and_Entrance_ramps_.28on-ramps.29|US follow these guidelines]]. For example a typical exit ramp would be named "Exit ##: Rest Area" (if numbered), or "Exit to Rest Area" if not numbered.
Generally the parking lot roads are not named, but if inside the city limits be sure to include the city name.
