Immediately after crossing under NY 454, the Sunken Meadow State Parkway continues northward into exit SM3, which serves as a cloverleaf interchange with NY 25 (Jericho Turnpike). The four-lane parkway continues north out of the interchange, immediately entering exit SM3A, which northbound connects to County Route 14 (CR 14; Indian Head Road). Southbound, this interchange serves Old Indian Head Road, and is signed as part of exit SM2. After exit SM3A, the Sunken Meadow bends northeast, becoming a divided highway once again, crossing through Smithtown. The parkway bends north once again, crossing under Scholar Lane before paralleling Old Commack Road under Old Northport Road. After a bend to the northeast, the parkway enters Kings Park.
