Eli5, why do roads have numbers assigned to them as well as names?

265 views

My kid asked me this question and I didn’t have a good quick answer. Also, I’m not referring to the US Interstate highway system. I am referring to the state and county level.

Any insight is much appreciated!

In the U.S. our highways have numbers to tell you which direction your going it even are north and south and odds are eat and west, i may have that backwards but that is why the numbers. As for names it depends on which names you mean, some were historical figures, sometimes its named after something in your county, city, or state. I have no idea who or how they decide what streets get what names. Hopefully someone here will.
