New York State Route 10 is a
New York State highway that runs from
Deposit, Delaware County to the
Hamilton County hamlet of Higgins Bay in the town of
Arietta. NY 10 starts at the same southern terminus as
NY 8 in Deposit. Similar to NY 8, NY 10 travels through the Central Leatherstocking Region of Upstate New York. The route heads roughly northward and reaches its northern terminus at NY 8 in Higgins Bay. Along the way it intersects
I-88 and
US 20.
NY 10 was designated in 1924 on the alignments of legislative Route 3, plus modern
NY 5 from Albany to
Schenectady,
NY 50 from Schenectady to
Saratoga Springs,
NY 9N between Saratoga Springs and
Lake George,
US 9 from Lake George to
Chestertown,
NY 8 between Chestertown and
Wevertown,
NY 28 from Wevertown to
North Creek,
NY 28N from North Creek to
Long Lake,
NY 30 between Long Lake and
Tupper Lake,
NY 3 near Tupper Lake, and NY 30,
NY 186, and
NY 86 from east of Tupper Lake to
Saranac Lake. Since then, several realignments have taken place.
Route description
Southern Tier

NY 10 begins here with NY 8 at its junction with NY 17 in Deposit.
NY 10 begins
concurrent with
NY 8 at an interchange with the
Quickway (
NY 17) southeast of the village of
Deposit near the
Broome-
Delaware County line. The two routes continue north along the eastern extents of Deposit to the banks of the
west branch of the Delaware River, where NY 8 breaks from NY 10 to cross over the river. NY 10, however, continues northeast along the riverbank, passing south of the Cannonsville Dam and the resulting
Cannonsville Reservoir behind it. Near the midpoint of the water body, NY 10 crosses over the reservoir on the Cannonsville Bridge and proceeds to follow the northern edge of the reservoir. As the reservoir begins to narrow, NY 10 intersects
NY 268, a connector route leading south to the village of
Hancock.
Past the end of the reservoir, NY 10 continues northeast in the vicinity of the Delaware River to
Walton, a village located directly on the banks of the river. Within the village limits, NY 10 overlaps
NY 206 along Delaware Street before separating from the route and proceeding east out of the village. NY 10 remains alongside the Delaware as it continues northeast to
Delhi, the home of the
State University of New York at Delhi. After passing along the eastern edge of the campus, NY 10 intersects and briefly overlaps
NY 28 through the village center before quietly leaving the area.

NY 10 overlaps
NY 145 in
Cobleskill; erroneous US-style shields are used to denote
northeast of Delhi in northeastern Delaware County, NY 10 passes through both
Hobart and
Stamford, a pair of villages located on the northernmost few miles of the Delaware's west branch. In the latter, NY 10 meets
NY 23. North of Stamford in
Schoharie County, NY 10 turns northeast, bypassing the tall Mine Hill, home to the source of the west branch of the Delaware. At the northern edge of the hill, NY 10 curves back to the northwest to serve the
Jefferson hamlet of the same name.
Outside of Jefferson, NY 10 continues onward through rural Schoharie County, passing through only small roadside hamlets before entering the village of
Richmondville, a community situated on
NY 7 and the Cobleskill Creek. NY 10 bypasses the village to the southeast, however, and intersects both NY 7 and
Interstate 88, the
limited-access highway that parallels much of NY 7, east of the village center. NY 10 turns east, overlapping NY 7 through the
State University of New York at Cobleskill campus and into
Cobleskill, where NY 7 and NY 10 intersect
NY 145 at Grand Street. Here, NY 10, as well as NY 145 (which is concurrent with NY 7 east of this point), leave NY 7 and continue north for two blocks before NY 10 leaves NY 145 and heads west out of the village on Elm Street.
Between Cobleskill and
Sharon Springs, NY 10 proceeds northwest through rural terrain once more, with the points of interest limited to a small number of hamlets. Midway between the two locations in
Seward, NY 10 intersects
NY 165, a connector leading to
Cooperstown via
NY 166 and Otsego County Route 52. In Sharon Springs, a village situated in northwest Schoharie County, NY 10 intersects
U.S. Route 20. Shortly after exiting the village, NY 10 passes into
Montgomery County.
Montgomery, Fulton and Hamilton Counties
Just across the county line, NY 10 passes through the village of
Ames, a small community based around the junction of NY 10 and County Routes 88 and 89 and situated south of the Canajoharie Creek. NY 10 crosses over the creek shortly afterward and follows the waterway downhill. Upon entering the village of
Canajoharie, NY 10 uses Reed Street, Walnut Street, and Rock Street which form a
switchback to ease the descent before entering a valley containing the conjoined
Mohawk River/
Erie Canal and the
New York State Thruway (
Interstate 90). Downtown, NY 10 intersects
NY 5S and passes under the Thruway before crossing into the neighboring village of
Palatine Bridge at the midpoint of the Mohawk River. On the northern riverbank, NY 10 meets
NY 5 and overlaps the route westward for a block before continuing northward into the largely rural town of
Palatine.
from Palatine Bridge, NY 10 passes into the
Fulton County town of
Ephratah and intersects
NY 67 just inside the county line. NY 67 turns north, joining NY 10 to the community of Ephratah, where it splits from NY 10 and heads east to
Johnstown. NY 10, however, continues northward in the vicinity of Caroga Creek to an intersection with
NY 29 near the hamlet of Garoga. The two routes join for roughly before separating as the roadway crosses over the
Blue Line into
Adirondack Park.
Adirondack Park

NY 10 overlaps
NY 29A passing through Caroga Lake
North of Rockwood, the community centered around the northern split of the NY 10/NY 29 overlap, NY 10 intersects NY 10A, an alternate route around Rockwood Lake to the east. Farther north, NY 10 enters Caroga Lake, a community situated on the eastern edges of West and East Caroga Lakes. In the center of the hamlet, NY 10 meets
NY 29A and follows the route out of the area. Together, NY 10 and NY 29A head northward through a region dotted with small lakes, as well as the larger Canada Lake, before splitting in the vicinity of Pine Lake.
Farther north, NY 10 passes directly between the Stoner Lakes, a pair of small water bodies separated by only NY 10, just south of where it crosses into
Hamilton County. For most of its run through the county, NY 10 parallels a waterbody, namely the west branch of the
Sacandaga River to where the Piseco Outlet flows into it, then the Piseco Outlet north to Big Bay near the community of Higgins Bay. NY 10 terminates soon after at an intersection with
NY 8 south of Piseco Lake, west of Spy Lake, and southwest of Higgins Bay.
History
Prior to 1924, the primary north-south roadway along the west bank of the
Hudson River from the
New Jersey state line near
New York City to
Albany, now largely
U.S. Route 9W, was designated as
Route 3, an unsigned
legislative route. All of legislative Route 3, plus modern
NY 5 from Albany to
Schenectady,
NY 50 from Schenectady to
Saratoga Springs,
NY 9N between Saratoga Springs and
Lake George,
U.S. Route 9 from Lake George to
Chestertown,
NY 8 between Chestertown and
Wevertown,
NY 28 from Wevertown to
North Creek,
NY 28N from North Creek to
Long Lake,
NY 30 between Long Lake and
Tupper Lake,
NY 3 near Tupper Lake, and NY 30,
NY 186, and
NY 86 from east of Tupper Lake to
Saranac Lake were designated as NY 10 upon the creation of the modern state highway system in 1924.

NY 8 at the current northern terminus of NY 10 in
Arietta The first change to the routing of NY 10 came by 1926 when NY 10 was extended northward over modern NY 3 to
Plattsburgh, where it terminated at
NY 30 (now
NY 22).
When
U.S. Routes were first signed in
New York in the following year,
U.S. Route 9W was assigned to the portion of NY 10 between New Jersey and Albany. NY 10 was then truncated to the former western terminus of its overlap with NY 5 in Schenectady.
In the
1930 renumbering, NY 10 was rerouted south of Long Lake and north of Tupper Lake over a combination of previously numbered routes and unsigned roadways. From Long Lake south, NY 10 followed modern
NY 30 to
Speculator and overlapped
NY 8 from Speculator to
Arietta, where it followed its modern alignment south to
Deposit. North of Tupper Lake, NY 10 followed what is now NY 30 through
Malone to the
Canadian border.
The segment of post-1930 NY 10 from Deposit to
Stamford was originally designated as
New York State Route 51 in the mid-1920s.
Farther north, the portion from
Palatine Bridge to Speculator was originally part of
NY 80, a designation assigned in the late 1920s. The remainder of modern NY 10 was originally unnumbered.
NY 10 was truncated to its current northern terminus in Arietta between 1959 and 1962 and largely replaced with NY 30 north of Speculator.
NY 10A

NY 10A
There are two highways that have been designated NY 10A.
- The current NY 10A is a
long two-lane spur providing an alternate connection from NY 29 in Fulton County. The route begins at NY 29 in Johnstown and heads northwest to end at NY 10 in Caroga just inside the limits of Adirondack Park. NY 10A serves as a link for motorists wishing to access the western parts of Caroga via NY 10 from NY 29, bypassing the Rockwood hamlet, a reduced speed zone, and about a mile of highway.
