New York State Route12D (NY12D) is a north–south state highway located in the northern part of New York in the United States. The southern terminus of the route is in the Oneida County village of Boonville, where it intersects NY12. The northern terminus is at a junction with NY12 in the Lewis County village of Lyons Falls. NY46 and NY294 are also present in the immediate area of the route's southern terminus.
NY12D was originally assigned as part of the 1930 renumbering of state highways in New York to most of what is now NY12 between Boonville and Lowville. The alignments of both routes between the two locations were swapped c.1939, placing NY12D on its current alignment from Boonville to Potters Corners (in the Town of West Turin) and on NY26 between Potters Corners and Lowville. The overlap between NY12D and NY26 remained in place until the 1970s when NY12D was realigned onto its current routing between Potters Corners and Lyons Falls, replacing then-New York State Route337.
Route description
Southern terminus of NY12D at NY12 in Lowville
NY12D begins at an intersection with NY12 at the southeastern edge of the village of Boonville in northern Oneida County. While NY12 bypasses the village to the east, NY12D heads northwest into the village on Main Street. At Schuyler Street, NY12D bears west for one block to Post Street, where it intersects the northern terminus of NY46. The eastern terminus of NY294 is located one block to the south at the junction of Post and Ford streets. NY12D, meanwhile, turns north at Post Street and follows the street out of the village and through the town of Boonville to the Lewis County town of Leyden.[3]
Within Leyden, NY12D passes through largely rural terrain with the exception of a pair of roadside communities: the hamlet of Talcottville on the Sugar River, a tributary of the nearby Black River, and the community of Locust Grove at the intersection of NY12D and Locust Grove Road. The route crosses into West Turin roughly 1 mile (1.6km) later, where it intersects NY26 at Potters Corners. NY26 turns north here to follow the right-of-way of NY12D; however, NY12D turns northeast onto the right-of-way of NY26 toward Lyons Falls. Near the western edge of the village, NY12D passes over NY12 with no access between the two. The connection is made a short distance to the southeast via McAlpine and Cherry Streets, which NY12D follows to terminate at NY12.[3]
History
In 1908, the New York State Legislature created Route27, an unsigned legislative route that initially extended from Forestport to Alexandria Bay via Boonville, Lowville, and Watertown. From Boonville to Lowville, Route27 used what is now NY12D and NY26.[4][5] When the first set of posted routes in New York were assigned in 1924, the segment of legislative Route27 between Boonville and Lowville via Potters Corners was designated as part of NY12.[6][7] An alternate route of NY12 between Potters Corners and Lowville via Lyons Falls was assigned NY12D as part of the 1930 renumbering of state highways in New York.[2] By the following year, NY12D was rerouted south of Lyons Falls to follow a routing similar to modern NY12 to Boonville.[8] The former routing of NY12D between Potters Corners and Lyons Falls was redesignated as NY337 c.1935.[9][10] The routings of NY12 and NY12D between Boonville and Lowville were swapped c.1939.[11][12]
Originally, NY12 entered Lyons Falls on Franklin Street and followed Center and McAlpine Streets through the village before leaving the area on Cherry Street.[13] NY12 was rerouted onto its current alignment around the western edge of Lyons Falls in the late 1940s;[14][15] however, NY337 was not truncated nor rerouted to meet the new path of NY12. Instead, NY337 was initially extended eastward along the former alignment of NY12 on McAlpine Street to a new terminus at Center Street.[16] It was rerouted east of Cherry Street to follow Cherry south to NY12 c.1970.[17] The former routing of NY337 along McAlpine Street from Cherry Street to a grade crossing with the Mohawk, Adirondack and Northern Railroad, a distance of 0.03 miles (48m), is now designated as NY970J, an unsigned reference route.[1] The overlap between NY12D and NY26 north of Potters Corners was eliminated c.1972 when NY12D was rerouted to follow NY337 to Lyons Falls, placing NY12D on its current alignment.[18][19]
