New York State Route 12D
North–south state highway located in the northern part of New York in the United States
New York State Route 12D (NY 12D) 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 NY 12. The northern terminus is at a junction with NY 12 in the Lewis County village of Lyons Falls. NY 46 and NY 294 are also present in the immediate area of the route's southern terminus.
NY 12D was originally assigned as part of the 1930 renumbering of state highways in New York to most of what is now NY 12 between Boonville and Lowville. The alignments of both routes between the two locations were swapped c. 1939, placing NY 12D on its current alignment from Boonville to Potters Corners (in the Town of West Turin) and on NY 26 between Potters Corners and Lowville. The overlap between NY 12D and NY 26 remained in place until the 1970s when NY 12D was realigned onto its current routing between Potters Corners and Lyons Falls, replacing then-New York State Route 337.
Route description

Why this record matters
The phrase “north–south state highway located in the northern part of New York in the United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 26, 2025. The linked authority identifier is Q2485948. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1930 and 1939.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
