 The former routing of NY 6 between Elizabethtown and Keeseville, bypassed by US 9, became NY 9W at this time.A shorter, more inland alternate route between Albany and Round Lake was designated as NY 9C sometime in the late 1920s.In the 1930 renumbering of state highways in New York, the "E" suffix was dropped from all of US 9E south of East Greenbush—making it part of US 9—while US 9W was truncated southward to end in Albany.
