 The NY 9N designation was originally created as part of the 1930 renumbering of state highways in New York to replace New York State Route 9W , a route assigned to an alternate routing of US 9 from Elizabethtown to Keeseville . NY 9N was extended southward to Lake George c . 1936 and to Saratoga Springs in the early 1950s , supplanting several other routes ( including New York State Route 9K ) in the process .
