about a half-mile (0.8 km) to another section of Purchase Street, where NY 120 turns to follow a slightly more northward track through another residential section of Harrison. Less than from I-287, NY 120 connects to the Hutchinson River Parkway by way of exit 27, a diamond interchange just northeast of the parkway's interchanges with I-287 and a reference route spur leading to I-684. Continuing northward from the parkway, the highway enters the hamlet of Purchase, where NY 120 runs along the eastern edge of Manhattanville College's campus and passes a short distance west of the State University of New York at Purchase. Part of Purchase Street near the entrance to SUNY Purchase at Anderson Hill Road is named the Specialist Anthony N. Kalladeen Memorial Highway in memory of United States Army Specialist Anthony Kalladeen, a SUNY Purchase student who was killed in Iraq in 2004. A dormitory at the school is also named for him. Another stretch of homes north of Purchase leads to Westchester County Airport, situated between NY 120 and the New York–Connecticut state line about to the east. Here, I-684 begins to run alongside NY 120 as both roads pass by Rye Lake, an offshoot of the Kensico Reservoir. NY 120 widens to four lanes ahead of the airport's main entrance in the town of North Castle, where the road connects to I-684 via Airport Road (unsigned County Route 135 or CR 135). North Castle to Millwood Continuing northward, I-684 and NY 120 head due north toward the state line, where NY 120A rejoins its parent route at a junction with King Street just north of the airport. From here, I-684 continues north into Connecticut while NY 120 takes on the King Street name and turns northwest to straddle the state line for roughly as a two-lane road. The route passes over I-684 and the northern tip of Rye Lake and serves an industrial complex in the Connecticut town of Greenwich before the state line turns 90 degrees to the northeast. NY 120 remains on a northwesterly alignment, however, and it crosses the Delaware Aqueduct prior to meeting NY 22 (Mount Kisco Road) on the edge of another Kensico Reservoir inlet. The two routes briefly overlap to cross the inlet on a causeway before splitting on the water body's north shore. From here, NY 120 heads through substantially less developed, mostly wooded areas as it traverses
