NY 9N is the longest suffixed route in the state, extending for from
Saratoga Springs to
Keeseville. The route stretches through four counties—
Saratoga,
Warren,
Essex and
Clinton—and serves several villages and
hamlets, including
Lake George,
Ticonderoga, and
Elizabethtown. It overlaps its parent route,
US 9, in Lake George and Elizabethtown and meets
Interstate 87 (I-87) four times. As NY 9N exits the city limits and enters the town of
Greenfield, it turns to follow a more northerly routing. It meets
County Route 21 (CR 21) just north of the town line, where the Church Street name ends, and
CR 36 (Wilton Road) to the north in the
hamlet of Greenfield Center. at NY 9N's southern terminus The route continues on into the
town of Corinth, where it crosses the
Blue Line into
Adirondack Park. Not far to the north, NY 9N enters the
village of Corinth, situated on the west bank of the
Hudson River. The highway follows Saratoga Avenue and Maple Streets into the village center, where it turns north and exits the village on Main Street. NY 9N follows the western edge of the river north for roughly through the towns of Corinth and
Hadley before crossing over it and passing from Saratoga County to Warren County.
Warren County Across the county line in
Lake Luzerne, NY 9N begins to deviate from the Hudson River, gradually curving to the northeast as it passes through the hamlets of
Lake Luzerne, Fourth Lake, and Lake Vanare, all of which are named for small lakes bearing those names near the center of the communities. Just northeast of Lake Vanare, NY 9N enters the
town of Lake George, where it connects to
I-87 (the
Adirondack Northway) at exit 21 and meets US 9. Here, it joins its parent route northward toward the
village of Lake George. The conjoined routes intersect the northern end of
NY 9L just south of the village line before becoming Canada Street and entering the village limits upon crossing over West Brook. US 9 and NY 9N serve as the primary north–south thoroughfare through the village before splitting at the north end of the village. While US 9 continues to the north, NY 9N heads northeast along the western edge of
Lake George. The portion of NY 9N between Lake George village and
Hague is relatively isolated, with mountains lining the western edge of the highway and the lakeshore located to the immediate east. Along this stretch, NY 9N serves numerous lakeside hamlets, the southernmost of which is Diamond Point, a community just south of the Lake George–
Bolton town line. The route continues on, passing through the hamlets of Bolton and
Bolton Landing, the latter of which is home to
The Sagamore, a resort situated on an island in Lake George. . North of Bolton Landing, the route leaves the main lake and instead follows the edge of Northwest Bay, an inlet separated from Lake George itself by a large, mountainous peninsula. The bay abruptly ends about to the north, at which point NY 9N curves to the east and proceeds through a pass in the mountains to rejoin the western edge of Lake George at Sabbath Day Point in the town of Hague. Here, the route turns back to the north and follows Lake George to the hamlet of Hague, where it meets the northern (signed as the eastern) terminus of
NY 8. NY 9N continues to serve as the lakeside roadway for another before curving away from the lake and entering
Essex County.
Essex and Clinton counties Now in the town of
Ticonderoga, NY 9N passes through a valley before curving to the east and entering the
hamlet of Ticonderoga. For the most part, NY 9N bypasses the community as it turns north onto Wicker Street, the westernmost north–south through street in the hamlet. Northwest of the former village's center, NY 9N meets
NY 22 and
NY 74, the latter of which serves as a northerly bypass of Ticonderoga. NY 22 joins NY 9N here, following the route out of the hamlet. NY 9N and NY 22 head generally northward through an area of lowlands, which eventually give way to
Lake Champlain as the conjoined routes pass into the town of
Crown Point. Once again, NY 9N serves as the lakeside highway as it follows the western edge of the lake through the hamlet of Crown Point to the peninsula that gives the town its name. While NY 9N and NY 22 pass by Crown Point to the west,
NY 185 directly serves the peninsula and the
Crown Point State Historic Site, located at its tip. The routes continue northward along the lakeshore through the town of
Moriah and the village of
Port Henry to the town of
Westport, where NY 9N and NY 22 split in the hamlet of Westport. While NY 22 continues north towards
Essex, NY 9N heads west to follow a more inland routing through a series of narrow valleys. NY 9N intersects I-87 once again at exit 31 just before entering the town of
Elizabethtown. The route continues west, passing over the
Bouquet River and entering the
hamlet of Elizabethtown, where it rejoins US 9 in the former village's center. Unlike the overlap in Lake George, this concurrency lasts for only three blocks before the two routes split. NY 9N continues to the west for through deep, narrow valleys to
Keene, where it meets
NY 73 north of Keene Valley. Here, NY 9N turns north, joining NY 73 for to the hamlet of Keene, located on the east branch of the
Ausable River. NY 73 heads off to the west from this point toward
Lake Placid; however, NY 9N follows the river northward into the town of
Jay, where it intersects the east end of
NY 86. The highway continues alongside the western bank of the river branch to the hamlet of
Au Sable Forks, situated on the Essex–
Clinton County line and at the point where the Ausable River's east and west branches come together. The highway enters Au Sable Forks from the south on South Main Street and becomes North Main Street upon crossing the west branch of the river and entering Clinton County and the town of
Black Brook. NY 9N immediately turns east upon crossing the river, following Ausable Street out of the hamlet and along the northern edge of the Ausable River into the town of
Au Sable. Here, NY 9N meets I-87 one final time at exit 34 just southwest of the village of
Keeseville. NY 9N continues on into Keeseville, where it meets NY 22 once again at an intersection across the river from the village center. NY 22 and NY 9N come together once more, overlapping for to an intersection with US 9 a short distance downstream from the center of Keeseville. NY 9N comes to an end here while NY 22 turns south onto US 9. ==History==
