New York State Route 1A (NY 1A) was a north–south state highway mostly located within New York City. It extended for just under 18 miles (29 km) from an intersection with NY 27 near the Holland Tunnel in Lower Manhattan to an interchange with U.S. Route 1 (US 1) just north of the New York City line in the Westchester County village of Pelham Manor. In Manhattan and the South Bronx, NY 1A used several surface streets to traverse the boroughs, including a handful of one-way roads. At the Bronx River, it began to follow limited-access highways, specifically the Bruckner Expressway and the Hutchinson River Parkway.
The route was among those created when routes were first marked in New York City in 1934. At the time, NY 1A ran from the Holland Tunnel to US 1 and the Pelham Parkway at Bronx Park. Over the next three decades, the route was gradually altered to accommodate changes in New York City's street network, including the construction of new roads and the conversion of parallel two-way streets into one-way couplets. The designation was eliminated in the early 1960s.
