ped with NY 9A along Old Saw Mill River Road (modern CR 303) to the east end of Neperan Road, where it broke from NY 9A and proceeded toward Hawthorne on then-Saw Mill River Road. The NY 142 designation was short-lived, however, as it was eliminated . By 1940, the portion of NY 142's former routing northeast of the NY 9A overlap was replaced by an extended NY 141 while the section east of the concurrency on Grasslands Road was redesignated as NY 100C. In the late 1940s, NY 9A was extended northward through Hawthorne to Ossining by way of a realigned Saw Mill River Road. The portion of Old Saw Mill River Road between Grasslands Road and the new highway became a short extension of NY 100C.
