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.
Pennsylvania Route 655 Pennsylvania Route 655 (PA 655) is an 83 mi north–south state highway located in central Pennsylvania. The southern terminus of the route is at the Mason–Dixon line in Thompson Township, where the road becomes a local road (Pennsylvania Avenue) in Hancock, Maryland. The northern terminus is at old U.S. Route 322 in Reedsville.
