New York State Route 74 (NY 74) and Vermont Route 74 (VT 74) are state highways in the northeastern United States, connected by one of the last remaining cable ferries in North America. Together they extend for 34 miles (55 km) 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 miles (32.89 km) 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 miles (21.34 km) later at a junction with VT 30 in the town of Cornwall.
