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 1/9 U.S. Route 1/9 (US 1/9) is the 31.01 mi long concurrency of US 1 and US 9 from their junction in Woodbridge Township, Middlesex County, New Jersey north to New York City. The route is a multilane road, with some freeway portions, that runs through urbanized areas of northern New Jersey adjacent to New York City. Throughout most of its length in New Jersey, the road runs near the New Jersey Turnpike/Interstate 95 (I-95). In Fort Lee, US 1/9 merges onto I-95 and crosses the Hudson River on the George Washington Bridge, where the two U.S. routes split a short distance into New York. US 1/9 intersects several major roads, including I-278 in Linden, Route 81 in Elizabeth, I-78 and US 22 in Newark, Route 139 in Jersey City, Route 3 and Route 495 in North Bergen, and US 46 in Palisades Park. Between Newark and Jersey City, US 1/9 runs along the Pulaski Skyway. Trucks are banned from this section of road and must use US 1/9 Truck. The concurrency between US 1 and US 9 is commonly referred to as "1 and 9". Some signage for the concurrency, as well as the truck route, combines the two roads into one shield, separated by a hyphen (1-9) or an ampersand (1&9).
