Route description

The western end of NY 100C is where it splits off as Old Saw Mill River Road from NY 9A (Saw Mill River Road). After 0.2 miles (0.3 km), Old Saw Mill River Road continues northwest as unsigned County Route 303 (CR 303) towards the hamlet of Eastview, while NY 100C turns right onto Grasslands Road. It immediately crosses over NY 9A again at a grade-separated intersection and begins its eastward journey. After another 0.9 miles (1.4 km), NY 100C meets the Sprain Brook Parkway by way of an interchange. The route comes to an end at NY 100 and NY 100A about 200 yards (180 m) beyond the Sprain Brook interchange.[4]

History

All of what is now NY 100C was originally designated as part of NY 142 ca. 1931. At the time, NY 142 overlapped 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.[5][6] The NY 142 designation was short-lived, however, as it was eliminated ca. 1938.[1][7] 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.[2] 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.[8][9]

Major intersections

The entire route is in Westchester County.
