NY 192 began at an intersection with NY 30 in the hamlet of Paul Smiths within the town of Brighton in Franklin County. The highway headed to the northeast, passing Cooler Pond to the south and Church Pond to the north. Just north of Church Pond was Osgood Pond, which was accessible at the first intersection, which was White Pond Road. NY 192 then headed eastward, intersecting with County Route 31 in the hamlet of Paul Smiths Easy Street. The highway turned to the southeast, intersecting with another county route and passing Brighton Town Park. At the intersection with CR 60 near the park, NY 192 entered Gabriels. NY 192 then continued to the southeast, intersecting with CR 55, its former routing eastward to NY 3 in Bloomingdale. At CR 55, NY 192 curved southward and passed into the town of Harrietstown. The route ended shortly afterward at a junction with NY 86 in the hamlet of Harrietstown east of the Adirondack Regional Airport.
History
When NY 3 was assigned in 1924, it followed a significantly different routing through the North Country than it does today. 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. NY 408 and the eastern half of NY 192 were included as part of NY 365. The new route extended from NY 5 southwest of Oneida to U.S. Route 9 in Plattsburgh. NY 365 initially overlapped both NY 192 and NY 408; however, NY 408 was removed, leaving only NY 365 on the Harrietstown–Gabriels roadway. NY 192, meanwhile, continued to overlap NY 365 from Gabriels to Bloomingdale. In the mid-1940s, NY 365 was rerouted between Wawbeek and Bloomingdale to overlap NY 3 instead. The portion of NY 365's former routing from Harrietstown to Gabriels was not initially assigned a new designation. The Harrietstown–Gabriels highway became a signed route once again in the early 1950s when it became NY 192A. Both NY 192 and NY 192A remained unchanged through the late 1970s. On January 7, 1980, NY 192A was supplanted by a realigned NY 192. Maintenance of NY 192's former routing between Gabriels and Bloomingdale was transferred to the counties it ran through—namely Franklin and Essex—in stages. The Franklin County portion was given to the county on April 1, 1980, while the section in Essex County was transferred to county control on April 1, 1985, as part of highway maintenance swaps between the state of New York and Franklin and Essex counties. On March 28, 1989, NY 192 was supplanted by a realigned NY 86.
