High Quality Content by WIKIPEDIA articles! New York State Route 352 (NY 352) is a state highway in the Southern Tier of New York, United States. It generally parallels the Southern Tier Expressway (Interstate 86 and NY 17) from the village of Riverside (exit 45) east through the city of Corning to the city of Elmira (exit 56). The portion of NY 352 west of the hamlet of Big Flats was once part of NY 17; the rest was originally New York State Route 17E. Construction of and improvements to the Southern Tier Expressway have resulted in extensions of NY 352, primarily along the former NY 17 right-of-way.
