The NY 76 designation was reassigned elsewhere in the state as part of the 1930 renumbering of state highways in New York. From Whitesboro to downtown Utica, NY 76's former alignment was co-designated as part of NY 5S and NY 12C. In the mid-1930s, a north–south connector between NY 5 in New Hartford and NY 5S and NY 12C in Yorkville was designated as NY 5A. NY 5S and NY 12C were realigned in the late 1930s to follow a new highway named Oriskany Boulevard through Whitesboro and Yorkville. In the early 1940s, NY 5S was truncated to begin in Utica while its former alignment between Rome and Utica became part of NY 69.
