In the early 1950s, NY 365's old routing between Harrietstown and Gabriels was designated as NY 192A, a spur route of NY 192. NY 192A was removed from the state highway system on January 7, 1980, when NY 192 was rerouted east of Gabriels to follow NY 192A. On March 28, 1989, NY 192 was eliminated in much the same way as its spur route as NY 86 was rerouted to follow NY 192 through Gabriels to Paul Smiths. NY 86's former routing past the Adirondack Regional Airport became NY 186.
