I am trying to learn the order of the Avenues. While I am l clear on the east side, I am a little confused on the west side.
Looking at my map, it looks as if the Ave's below about 57th-59th St. are referred to as numbered Ave's, and above that point, they are referred to as Columbus Ave, Amsterdam Ave, etc.
Do I have this correct? If so, what is the "dividing line" between where they are referred to as numbered aves vs. named aves?
