Great Setup by NY DOT

[Duke87]

The argument that I hear the most about not switching the interchange numbers is that it won't work well in the five boroughs.  I have countered that they could do a hybrid system whereas the five boroughs stick to their existing numbers and the highways that head upstate could switch from sequential to distance where the milepost number becomes higher than the interchange number.

Or better yet, isolate the boroughs further, by having those roads which travel "upstate" reset to MP 0 at the city/county border.  So in that case, the Thruway would still have its MP 0/EXIT 1 in Yonkers where it does presently.

Nonono, that's worse, not better. No resetting the exit numbers mid-route! As it stands that already causes confusion.

Considering several highways in NYC already have suffixed exits (and not just on distance-based highways), I don't see what the fuss is about.

Though, you could probably leave the numbers on the parkways alone and not have much be lost. That's where most of the dense spacing which would result in alphabet soup is, anyway.
