New York State Route 429 (NY 429) is a north–south state highway located entirely within Niagara County, New York, in the United States. It extends for from an intersection with NY 265 and NY 384 in North Tonawanda to a junction with NY 104 (Ridge Road) on the border between the towns of Cambria and Lewiston. Although it is relatively minor in length, the route is regionally important nonetheless as it connects North Tonawanda to some of the county's interior regions. About midway between North Tonawanda and Ridge Road, NY 429 serves the hamlet of Sanborn, where it briefly overlaps with NY 31. At Pekin, a community situated between Sanborn and NY 104, NY 429 descends the Niagara Escarpment. The Sanborn–Ridge Road segment of modern NY 429 was originally designated as part of Route 30, an unsigned legislative route, in 1908. In the mid-1920s, the portion of Route 30 west of Rochester became part of the signed NY 31; however, NY 31 was realigned in the late 1920s to follow Ridge Road west from Cambria to the village of Lewiston. NY 31's former alignment from Niagara Falls to Ridge Road via Sanborn became New York State Route 31A at this time. NY 31A was eliminated in 1935 as part of the establishment of U.S. Route 104 (US 104). The portion of its former routing north of Sanborn became part of NY 429, which was extended from its terminus. Route description NY 429 begins on the banks of the Niagara River at a junction with NY 265 and NY 384 in downtown North Tonawanda. The route heads east as Wheatfield Street, crossing the CSX Transportation-owned Niagara Subdivision at a grade crossing that separates an industrialized block of the street from more residential sections to the east. After three blocks, NY 429 turns onto Oliver Street and follows it northwestward through residential and industrial portions of the city, paralleling NY 265 and NY 384 for to a junction with Ward Road. Oliver Street and Ward Road merge here, and the combined street takes on the Ward Road name as it proceeds due northward through the solely residential northern portion of North Tonawanda. NY 429 exits the city near a junction with Ruie Road, at which point maintenance of the route shifts from the city to the New York State Department of Transportation (NYSDOT). Now in the town of Wheatfield, NY 429 heads
