 In 1908 , the New York State Legislature created Route 22 , an unsigned legislative route that was initially split into two segments . The northern half of the route ran from <unk> to Rouses Point and mostly followed what is now US 9 between the two locations . From Elizabethtown to Keeseville , however , Route 22 followed a more westerly alignment via Keene , Jay , and Au Sable Forks . When the first set of posted routes in New York were assigned in 1924 , all of legislative Route 22 north of <unk> became part of NY 6 , which continued south toward Glens Falls on what is now US 9 . At the same time , the section of modern NY 9N between Saratoga Springs and Lake George was designated as part of NY 10 . The portion between Ticonderoga and Westport became part of a realigned NY 30 by the following year .
