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.
U.S. Route 30 in Pennsylvania In the U.S. state of Pennsylvania, U.S. Route 30 (US 30) runs east–west across the southern part of the state, passing through Pittsburgh and Philadelphia on its way from the West Virginia state line east to the Benjamin Franklin Bridge over the Delaware River into New Jersey. In Pennsylvania, US 30 runs along or near the transcontinental Lincoln Highway, which ran from San Francisco, California to New York City before the U.S. Routes were designated. (However, the Lincoln Highway turned northeast at Philadelphia, using present U.S. Route 1 and its former alignments to cross the Delaware River into Trenton, New Jersey.)
