In the 1960s, NY 328 was realigned between Seeley Creek and Southport to follow a new roadway built to bypass the hamlets of Seeley Creek, Webb Mills, and Pine City. The realignment coincided with the designation of the route as part of Corridor U of the Appalachian Development Highway System in 1965. The former alignment of NY 328 between Seeley Creek and Southport is now CR 69.
