Back to other exit lists.
US 50/301 is freeway until the east split. For the length of this exit list, there are no driveways on US 301. IOW it can be easily converted to freeway all the way to DE, and in fact several interchanges have been built. Interestingly there are also no traffic lights (but lots of blinkers); when traffic gets heavy enough for a light an interchange is built.
