Well it does exist in the real world, but I think your imaginary town still has to lie somewhere on
Route 66
I’m not clear on the OP’s requirements.
If the song was written about a real street in a real place, like “Lake Shore Drive” by AH&J, then it doesn’t count.
But if the song was written about a generic street in no place in particular, but there really is such a street someplace, then it still counts? Like “Seven Bridges Road,” for example?
Anyway, at least one street in out town should have a Dead Man’s Curve (Jan & Dean).
There is that street in the U.S. Navy Anthem - Anchorsa Way.
