US571

US 571 was a United States Numbered Highway that ran through the state of New York. The highway's designation was established in 1926 and it was decommissioned in 1938. The route originally began at the Pennsylvania state line near Elmira and traveled north, terminating at US 11 in Whitney Point. Its length was approximately 47 miles.

The primary purpose of US 571 was to connect the city of Elmira with communities further north in New York State. It followed a generally north-northwesterly alignment for its entire route. Over its short lifespan, the highway's path was largely consolidated into New York State Route 17.

When US 571 was decommissioned in 1938, its former routing was absorbed into the state highway system. This reallocation was part of a broader effort by the New York State Department of Transportation to rationalize and simplify the state's road network. The number US 571 has not been reused for any other highway in the United States.
