NY 192 was assigned as part of the 1930 renumbering of state highways in New York to an alignment extending from Paul Smiths to Bloomingdale.

NY 192 then headed eastward, intersecting with County Route 31 (CR 31, named Jones Pond Road) in the hamlet of Paul Smiths Easy Street.

The highway turned to the southeast, intersecting with another county route and passing Brighton Town Park.

The route ended shortly afterward at a junction with NY 86 in the hamlet of Harrietstown 2 miles (3.2 km) east of the Adirondack Regional Airport.

[7] 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.

[3][18] 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.
