The Saw Mill River Parkway and the Harlem Line parallel once again in the northern reaches of Pleasantville, paralleling the Saw Mill River into the town of New Castle. Now in the hamlet of Chappaqua, exit 32 southbound accesses NY 120 at Mill River Road. Nearby this junction is the Chappaqua Metro-North station. After crossing under NY 120, the northbound exit 32 connects to Hunts Place, which connects to NY 120. Running along a hillside in New Castle, the parkway becomes a divided highway for a short distance, becoming a two-lane roadway northbound. No interchange is present along this stretch and the lanes come back together just south of exit 33, an at-grade intersection with Readers Digest Road. At this interchange, the parkway has access to the former Global Headquarters of Reader's Digest and nearby NY 117.
