New York State Route 120 (NY 120) is a state highway in southern Westchester County, New York, in the United States. It begins in the city of Rye at an intersection with U.S. Route 1 (US 1) and runs for about north to the hamlet of Millwood, where it ends at a junction with NY 100. The route intersects with Interstate 684 (I-684) and the Saw Mill River Parkway, and serves the Westchester County Airport in North Castle. Portions of the route have been signed ceremonially in remembrance of American serviceman killed in the 2000s and 2010s during the wars in Iraq and Afghanistan. NY 120 was assigned as part of the 1930 renumbering of state highways in New York, but only to the portion of its routing north of Westchester Avenue. It was extended south to Rye , then rerouted to follow Westchester Avenue east to Port Chester by the following year. Most of NY 120's former routing to Rye became part of New York State Route 119A at that time. NY 120 was rerouted to serve Rye again in October 1960, replacing NY 119A. Route description Rye to Harrison NY 120 begins at an intersection with US 1 (Boston Post Road) in the city of Rye. The route proceeds northward along Purchase Street as a two-lane street through the Locust Avenue Business District, intersecting a handful of local streets and serving Rye's station on the Metro-North Railroad's New Haven Line. Past the station, the highway passes under the New Haven Line, Amtrak's Northeast Corridor line, and I-95 in quick succession ahead of the Purchase Street Business District. The commercial surroundings give way to residential neighborhoods after three blocks as NY 120 winds northward through the northern part of Rye to the adjacent village/town of Harrison. In Harrison, NY 120 passes several mansions on both sides of the highway as it gradually turns northwestward and approaches I-287 (the Cross Westchester Expressway). The route parallels the western edge of the freeway for several blocks to Westchester Avenue, where NY 120 meets the southern end of NY 120A, an alternate route through the easternmost part of Westchester County. While NY 120A heads east toward Port Chester, NY 120 takes on the Westchester Avenue name as the two directions of the route split to follow collector/distributor roads running northwestward along both sides of I-287. The route remains on the frontage roads for
