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 955 Pennsylvania Route 955 (designated by the Pennsylvania Department of Transportation as SR 0955) is a 3.80 mi state highway that runs between Pennsylvania Route 5 in Lawrence Park and U.S. Route 20 in Harborcreek Township. Route 955 continues to travel away from Route 5 as Iroquois Avenue in a diagonal until it reaches Nagle Road, where it straightens out and runs parallel to US 20. The highway stays parallel until US 20 makes a sharp left turn and intersects with Route 955. The route was first signed in 1928 and widened from Route 5 to an intersection with Nagle Road with a grassy median between 1950 and 1958.
