[edit] History

In 1980, NY 21's northern terminus was moved southward from the intersection with Lake Road (formerly New York State Route 18) in Pultneyville to its present location at the intersection with NY 104 in Williamson.

Before the 1930 renumbering, the number 21 was assigned to the route from Poughkeepsie to Amenia (present day U.S. Route 44).
