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.
Interstate 71 Interstate 71 (I-71) is a north-south (physically northeast-southwest) Interstate Highway in the Great Lakes/Midwestern and Southeastern region of the United States. Its southern terminus is at an interchange with Interstate 64 and Interstate 65 (the Kennedy Interchange) in Louisville, Kentucky. Its northern terminus is at an interchange with Interstate 90 in Cleveland, Ohio. I-71 runs concurrently with Interstate 75 from a point about 20 mi south of Cincinnati, Ohio into downtown Cincinnati. Almost three quarters of the route lies east of I-75, thereby putting it out of its proper place in the Interstate grid.
