324 between Niagara Falls and Tonawanda via Grand Island was designated as NY 325. NY 324 was extended northward to NY 384 in Niagara Falls , supplanting the entirety of NY 325. The NY 325 designation was reassigned to the short piece of Sheridan Drive not designated as NY 324. The route was extended one final time by 1948 to follow NY 384 westward from the North Grand Island Bridge into downtown Niagara Falls. NY 324 remained unchanged until January 1, 1962, when the overlap with NY 384 was removed. Although the overlap with the new I-190 on the North Grand Island Bridge was also removed from maps during the same period, and is no longer signed, this overlap was never officially removed from either NYSDOT's description of the route or the annual NYSDOT Traffic Data Report.
