New York State Route 120A (NY 120A) is a state highway in southern Westchester County, New York, in the United States. It serves as an alternate route to the southern half of NY 120 running along the New York–Connecticut state line. The southern terminus of route is at NY 120 in Harrison. Its northern terminus is at NY 120 in North Castle. Most of the route straddles the New York–Connecticut state line, and part of the route is physically located in Connecticut. However, this part of the highway is not recognized by Connecticut as "Route 120A", and is considered to be part of NY 120A by the New York State Department of Transportation (NYSDOT). ==Route description== NY 120A begins at an intersection with NY 120 next to I-287 (the Cross-Westchester Expressway) in the village of Harrison. Although the route is signed north–south, it initially heads east along Westchester Avenue, overlapping with the northbound direction of NY 120 for as the road passes under I-287. East of the freeway overpass, NY 120 leaves to the northwest while NY 120A continues eastward on the four-lane Westchester Avenue. It serves residential areas until it crosses into Rye Brook, where the street makes a turn to the southeast and soon enters more commercialized neighborhoods. In the center of Rye Brook, the route meets Ridge Street (unsigned County Route 54 or CR 54). The businesses give way to homes east of the junction, and NY 120A passes into the village of Port Chester just three blocks from Ridge Street near an intersection with Bowman Avenue (CR 104). Inside the village limits, maintenance of NY 120A shifts from the state to Westchester County, which inventories the route as CR 112. Continuing on, the road narrows to two lanes ahead of Port Chester's central business district, where NY 120A passes the Port Chester Public Library and the village's post office ahead of a junction with Pearl Street three blocks west of U.S. Route 1 and two blocks west of the Metro-North Railroad. Here, NY 120A turns off Westchester Avenue and onto North Pearl Street,〔 becoming a village-maintained route in the process.〔 The route's northeastward run on North Pearl Street is brief, however, as NY 120A turns northwest onto King Street after just two blocks.〔 As the route heads away from Pearl Street and Port Chester's commercial center, the blocks of businesses are gradually replaced with the residential neighborhoods that comprise most of northern Port Chester. About north of Pearl Street, NY 120A passes Lyon Park〔 and reverts to a state-maintained road at an intersection with Putnam Avenue (unsigned NY 982C).〔 Continuing on, the highway serves King Street School before crossing from Port Chester to Rye Brook several blocks later. In the latter village, the route slowly bends northward toward the Connecticut state line. It eventually reaches the boundary, at which point NY 120A begins to run northwestward along the state line, with the southbound lane in New York and the northbound lane in Connecticut. A short distance later, the route connects to the Hutchinson River Parkway and its Connecticut continuation, the Merritt Parkway (Route 15), by way of a modified cloverleaf interchange.〔 Not far from the interchange, the highway bends northward to fully enter Connecticut.〔 Although the road is located outside of New York, it is maintained by NYSDOT and considered by the DOT to be part of NY 120A. In Connecticut, NY 120A travels generally northwestward through the town of Greenwich, intersecting several streets of local importance, including Greenwich's locally maintained continuation of Anderson Hill Road (CR 18). The foray into Connecticut ends soon afterward, and the route proceeds to straddle the state line for another . Along this stretch, the route passes a series of commercial buildings in an otherwise residential area. Another New York-maintained stretch in Greenwich, Connecticut, soon follows as the route veers north to bypass the grounds of Westchester County Airport. As the route heads past the airport, it meets Rye Lake Road, Greenwich's connection to both the airport and Airport Road (CR 135).〔 Past Rye Lake Road, NY 120A serves the Griffith E. Harris Golf Club and several mansions on its way back to the New York–Connecticut state line. Just north of the airport, NY 120A turns westward onto Gateway Lane, a small east–west street leading back into New York and the town of North Castle. Gateway Lane and NY 120A both end just inside the state line at an intersection with NY 120. Here, NY 120 changes names from Purchase Street to King Street as the route continues NY 120A's course along the state line.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New York State Route 120A」の詳細全文を読む スポンサード リンク
