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.
State Route 74 (New York–Vermont) New York State Route 74 (NY 74) and Vermont Route 74 (VT 74) are adjoining state highways in the northeastern United States, connected by one of the last remaining cable ferries in North America. Together they extend for 34 mi through Essex County, New York, and Addison County, Vermont. NY 74 begins at exit 28 off Interstate 87 (I-87) in the hamlet of Severance in the Adirondack Mountains region of the northern part of New York State. It extends 20.44 mi to the western shore of Lake Champlain in Ticonderoga. There, the seasonal Fort Ticonderoga–Larrabees Point Ferry carries cars across the state border into Vermont, where VT 74 starts at the lake's eastern shore and terminates 13.26 mi later at a junction with VT 30 in the town of Cornwall.
