the northeastern edge of the reservoir. North of the reservoir, NY 120 crosses the northernmost part of the Bronx River and traverses the northeastern corner of the town of Mount Pleasant, where the woods give way to a handful of residential neighborhoods. The transition in surroundings continues into the adjacent town of New Castle, home to housing tracts that become less isolated as the road veers westward toward the hamlet of Chappaqua. NY 120 proceeds west through residential and commercial areas to Chappaqua's central business district, where it meets the community's main north–south route, NY 117 (Bedford Road). NY 120 heads north through the center of Chappaqua, overlapping with NY 117 to reach another section of King Street one block to the north. Past NY 117, NY 120 continues generally westward through Chappaqua, changing names to Quaker Road a short distance east of Chappaqua's station on the Metro-North Railroad's Harlem Line. After crossing the Harlem Line, the route dips under the Saw Mill River Parkway and intersects two parallel local streets leading to the parkway's exit 32. NY 120 turns northward here, crossing over the Saw Mill River and leaving Chappaqua for less densely populated areas of the town of New Castle. At north of Chappaqua early 19th-century farmhouses that clustered around the Quaker meeting house that was then the center of Chappaqua, line the road. Today these are listed on the National Register of Historic Places as the Old Chappaqua Historic District. Roughly past the historic district, NY 120 makes a gradual turn to the west to reach a junction with NY 133 (Millwood Road). NY 120 turns onto NY 133, following Millwood Road westward into the hamlet of Millwood and its commercial center. Here, the two routes cross the right-of-way of the former Putnam Division of the New York Central Railroad and pass by the site of Millwood's station, which was demolished in May 2012 after years of neglect. Just after the railroad right-of-way, NY 133 turns southwestward onto Station Place while NY 120 proceeds northwest as Millwood Road for one more sparsely developed block before terminating at a junction with NY 100 (Saw Mill River Road) at the northern edge of the hamlet. History The segment of modern NY 120 between Westchester Avenue and the north end of the overlap with NY 22 was originally designated as part of Route 1, an unsigned legislative route, by the
