NY 120 was altered again by the following year to follow NY 119 east along Westchester Avenue to US 1 in Port Chester. Most of NY 120's former routing south of Westchester Avenue became part of NY 119A, a new route assigned to all of Purchase Street between NY 119 and NY 120 in Harrison and US 1 in Rye. NY 120 was realigned once more in October 1960 to follow Purchase Street south to Rye, supplanting NY 119A. At the same time, NY 119 was truncated on its east end to Purchase Street while the portion of Westchester Avenue that had carried NY 119 and NY 120 between Purchase Street and Port Chester became an extension of NY 120A.
