I don't know what the problem is with the people who came up with the names/numbers for the roads in New York state.  In the north Catskills, there are Routes 23, 23A, 23B, and 23C, all of which travel in varying directions, sometimes running parallel to one another, sometimes perpendicular.  Nearby is Route 9W which, contrary to the convention used by every other road in every other town in every other state in the entire country (if not the world), employs the "W" not as a directional indicator but simply as an arbitrary letter to differentiate it from Route 9.  (Oh, and it goes north-south, which I suppose makes it easier.  I can kind of understand going on 9W South.  My brain would melt if I had to go on 9W East.)  Here's an idea:  Use a different number.  Surely there aren't 999 numbered roads in New York and they simply ran out of numbers.  If so, there are 9000 other 4-digit possibilities.  Pick one. #travel
