New York State Route 22
longest north–south state highway in New York
New York State Route 22 (NY 22) is a north–south state highway that parallels the eastern border of the U.S. state of New York, from the outskirts of New York City to the hamlet of Mooers in Clinton County near the Canadian border. At 337 miles (542 km), it is the state's longest north–south route and the third longest state route overall, after NY 5 and NY 17. Many of the state's major east–west roads intersect with, and often join, NY 22 just before crossing into the neighboring New England states, where U.S. Route 7 (US 7), which originally partially followed NY 22's alignment, similarly parallels the New York state line.
Almost all of NY 22 is a two-lane rural road through small villages and hamlets. The exceptions are its southern end in the heavily populated Bronx and lower Westchester County, and a section that runs through the city of Plattsburgh near the northern end. The rural landscape that the road passes through varies from horse country and views of the reservoirs of the New York City watershed in the northern suburbs of the city, to dairy farms further upstate in the Taconic and Berkshire mountains, to the undeveloped, heavily forested Adirondack Park along the shores of Lake Champlain. An 86-mile (138 km) section from Fort Ann to Keeseville is part of the All-American Road known as the Lakes to Locks Passage.
The oldest portions of today's NY 22, in Westchester County and along the Lake Champlain shoreline, were Native American trails. Dutch, and after them English, settlers continued to use the road to get their farm products to market, with the southernmost portion eventually becoming the White Plains Post Road in the 18th and 19th centuries. In the early 20th century, as automobile use became widespread, the state paved the more heavily used sections and built new roads to create the current highway, first designated as NY 22 in 1930.
