 The entirety of modern @-@ day NY 164 was originally designated as NY 312 in the 1930 renumbering of state highways in New York . When the NY 312 designation was shifted south to its current location in the town of Southeast c . 1937 , its former routing in Patterson became part of an extended NY 216 , which connected with its current routing by way of modern NY 311 , NY <unk> and NY 55 . NY 216 was truncated to its current length on January 1 , 1970 . The portion of its former alignment between NY 311 and NY 22 was then redesignated as NY 164 .
