New York State Route 3 (NY 3) is a major east–west state highway in New York, in the United States, that connects central New York to the North Country region near the Canadian border via Adirondack Park. The route extends for between its western terminus at an intersection with NY 104A in the Cayuga County town of Sterling and its eastern terminus at a junction with U.S. Route 9 (US 9) in the Clinton County city of Plattsburgh. NY 3 traverses eight counties and is a lakeside roadway from Mexico to Sackets Harbor, a mountainous route in Adirondack Park, and an urban arterial in Fulton, Watertown, and Plattsburgh. In 1924, the segment of the Theodore Roosevelt International Highway within New York was designated NY 3. At that time, it spanned the full east–west length of the state, extending from the eastern bank of the Niagara River in North Tonawanda to the western edge of Lake Champlain in Plattsburgh; however, the routing through the North Country was significantly different at that time from its modern alignment. The route was moved onto its modern routing east of Watertown as part of the 1930 renumbering of state highways in New York; it was truncated to Sterling on its western end and rerouted to follow its current alignment from Sterling to Watertown roughly five years later. Since 1924, there have been 14 suffixed routes of NY 3, all designated between NY 3A and NY 3G. Of these, all but one only existed during the 1930s. The only active designation is NY 3A, which was assigned in the 1950s to an alternate route of NY 3 in Jefferson County. ==Route description== A substantial portion of NY 3 travels east–west across northern New York and passes through the northern part of the Adirondack Mountain Range. Much of this section of the highway is named as part of the Olympic Trail Scenic Byway. The areas NY 3 passes through alternate between long stretches of rural area, consisting of a mix of open terrain and dispersed residences, and compact settlements containing concentrations of houses and businesses. NY 3 is classified mainly as a minor arterial road, the major exception being the section that is concurrent with NY 812, which is a principal arterial road. Most of the route is maintained by the New York State Department of Transportation. Exceptions are in the cities of Watertown and Plattsburgh, where at least part of the road is city-maintained. In Watertown, NY 3 is locally maintained from Massey Street (southbound US 11 junction) to the end of the NY 3/NY 12 overlap. The route is entirely city-maintained in Plattsburgh. 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 3」の詳細全文を読む スポンサード リンク
