westerly alignment to the hamlet of Islip along Joshua's Path and Islip Avenue, two streets that ran parallel to the route's original path on Carleton Avenue and Wheeler Road. Ownership and maintenance of NY 111's former routing was transferred to Suffolk County, which redesignated the road as CR 17. The ultimately cancelled eastern extension of the Northern State Parkway would have crossed NY 111 just south of Village of the Branch at a point north of Mount Pleasant Road. An interchange between the parkway and NY 111 was planned at that location.
