N. W. Perry
| Over 500 roads criss-cross the state with a NY
shield. The signed routes are numbered 2-878. New York also has a
significant amount of unsigned roads, numbered 900 and above. There is
no apparent numbering scheme at work in the state except for a some
clustering in a couple of areas (101-112 for example). Spurs off of a roads are
designated by a NY ##A where ## is the number of the main road and A is
an alphabetical suffix. See US 9 and its
many spurs for an example.
For a historical point of view and details about some of these roads and others that were never built, go to Steve Anderson's site. His pages contains information on just about every highway in the New York City area.
