A question about how roads are determined to be different types of roads.

Question

What distiguishes a road from an Ave, a Rd, a Boulivard, a street.??

Answer 1

Avenues run north and south. Streets run east and west. Boulivards have grassy medians. Roads join up with rural roads that go to another city or town and/or run in all directions. This is absolutely true except in places that do it differently.
