 At the time, the route also extended west into Oneida on what is now NY 365A and northeast through the North Country to Plattsburgh by way of several pre-existing state routes.NY 365 was realigned to bypass Oneida in 1949—giving way to NY 365A—and truncated to end at NY 12C (partly now NY 291) in the late 1950s.The route was extended to its present eastern terminus on January 1, 1970, following the elimination of NY 12C and NY 287.
