As of June 27, 2014, the United States Route 15 going through New York State was redesignated as what motorway, running from central Pennsylvania through southern New York?
Interstate 99 Interstate 99 (I-99) is an Interstate Highway with two segments: one located in central Pennsylvania, and the other in southern New York in the United States. The southern terminus of the route is at exit 146 of the Pennsylvania Turnpike (I-70 and I-76) north of Bedford, where the road continues south as U.S. Route 220 (US 220). The northern terminus of the Pennsylvania segment is at I-80 near Bellefonte. The New York segment follows US 15 from the Pennsylvania–New York border to an interchange with I-86 in Corning. I-99 passes through Altoona and State College—the latter home to Pennsylvania State University—and is entirely concurrent to US 220, within Pennsylvania. Long-term plans call for I-99 to be extended southward along the US 220 corridor to an interchange with I-68 in Cumberland, Maryland.
New York State Route 14A New York State Route 14A (NY 14A) is a north–south state highway located in the Finger Lakes region of New York in the United States. It extends for 35.99 mi from an interchange with NY 14 in the Schuyler County town of Reading to an intersection with U.S. Route 20 (US 20) and NY 5 west of the Ontario County city of Geneva. In between, the two-lane route serves Yates County and the village of Penn Yan, located at the northeastern tip of Keuka Lake. Outside of Penn Yan, NY 14A traverses rural, rolling terrain dominated by farmland.
