 NY 3 entered Franklin County near Hogansburg and served Malone, Paul Smiths, Gabriels, and Harrietstown before leaving the county near Saranac Lake.In the 1930 renumbering of state highways in New York, NY 3 was rerouted east of Watertown to follow its modern alignment through the North Country.The portion of NY 3's former routing from Harrietstown to a junction southeast of Gabriels was designated as NY 408 while the segment between Paul Smiths and the vicinity of Gabriels became part of NY 192, an east–west highway extending from Paul Smiths to the realigned NY 3 in Bloomingdale.
