New York State Route 392 (1936–1974)

New York State Route 392 (NY 392) was a state highway in the vicinity of the city of Ithaca in central Tompkins County, New York, in the United States. The western terminus of the route was at an intersection with NY 79 in downtown Ithaca. Its eastern terminus was at a junction with NY 366 in the hamlet of Varna, located within the town of Dryden. NY 392 served as a connector between Ithaca, Varna, and the campus of Cornell University.

The routing of NY 392 was originally part of NY 13 in the 1920s. NY 13 was realigned in the mid-1930s to bypass Cornell University from the south, at which time the portion of its former alignment from Stewart Avenue to Varna was redesignated as NY 392. The route was extended southwest into downtown Ithaca over the remainder of NY 13's former routing in the mid-1960s before it was removed on July 1, 1974. All of former NY 392 is now locally maintained.
