New York State Route 128
State highway in Westchester County, New York, US
New York State Route 128 (NY 128) is a 5.53-mile (8.90 km) long north–south state highway in northern Westchester County, New York. The route begins at an intersection with NY 22 just west of I-684 in the hamlet of Armonk. Crossing through downtown Armonk, the route connects to NY 117 in the southern end of the village of Mount Kisco.
NY 128 was first constructed during the early 1900s with a pair of contracts handed out by the state of New York, which constructed the new alignment between NY 22 and the triangle junction with NY 117 in Mount Kisco. These segments were both added into the state highway system in 1903. NY 128 itself was designated in the 1930 renumbering of state highways from Armonk to Mount Kisco. This was extended in the mid-1930s to connect to the Connecticut state line at Riversville Road. However, in 1971, the state truncated NY 128 back to NY 22 in Armonk and renumbered the short connector as NY 433.

Why this record matters
The phrase “state highway in Westchester County, New York, US” 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.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Apr 26, 2025. The linked authority identifier is Q2486273. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1903, 1930 and 1971.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
