True; there are three decent ways from what I can tell: NY 3 (and 3A), US 11 (with NY 11B if you so desire)/NY 190, and NY 12/NY 37/NY 122/US 11/NY 190. The APA would never allow expanding the first one. I guess it comes down to what villages you want to service along the way (even if it means upgrading state roads from the highway), and how far north the Adirondacks (not the park, but the physical mountains) stretch and what you can get away with; obviously Beartown is along 190, you have park around St. Regis Falls if you go too far south towards 11B, is it more important to service Ogdensburg/Massena or Canton/Potsdam, perhaps Akwesasne will have a say...
