 When the first set of posted routes in New York were assigned in 1924, the section of legislative Route 5 between Mohawk and Paines Hollow became part of NY 28.In the 1930 renumbering of state highways in New York, NY 28 was realigned to use its modern alignment between Cooperstown and Mohawk while its former routing from Mohawk to Paines Hollow was redesignated as NY 168.The route was extended eastward to NY 80 in Starkville .
