 NY 365 was truncated southwestward to its junction with NY 12C west of Holland Patent in the late 1950s, eliminating the bevy of overlaps between NY 365 and other routes in the North Country.The overlap between NY 365 and NY 46A was eliminated in the early 1950s after NY 46A was renumbered to NY 274 and truncated to run only from Holland Patent to Western.Originally, modern NY 365 between Barneveld and NY 8 in Ohio was designated as NY 287 in the 1930 renumbering.
