 The overlap with NY 12E was slightly reduced in length by the following year when the alignments of NY 12E and NY 12F east of NY 179 were flipped, placing both routes on their modern alignments.NY 179 itself remained unchanged until October 1963, when the designation was completely removed.The portion of NY 179 south of Limerick became a southward extension of NY 180, which connected to Limerick by way of a previously unnumbered roadway between NY 12 and NY 12E.
