New York State Route 9N Much of NY 9N runs alongside either a river or a lake. It follows the Hudson River through northern Saratoga County and southern Warren County, the entirety of Lake George's western shoreline, the west edge of Lake Champlain between Ticonderoga and Westport, and the Ausable River from Keene to Keeseville. The other portions of NY 9N pass through predominantly rural and mountainous regions of the Adirondack Mountains. The NY 9N designation was originally created as part of the 1930 renumbering of state highways in New York to replace New York State Route 9W, a route assigned to an alternate routing
New York State Route 373 America. The park was further protected in 1894 when a clause was added to the New York State constitution which banned the selling of timber from state parks. On April 16, 1827, a team of three surveyors were commissioned to determine a routing for a new highway leading from Hopkinton, a town in northeastern St. Lawrence County, to Lake Champlain. The task took 26 days, after which it was determined that the highway would meet Lake Champlain at Fort Kent. An act authorizing the construction of the highway was passed by the New York State Legislature on April 18, 1829.
