State highways in Vermont

New York State Route 314 (NY 314) and Vermont Route 314 (VT 314) are a pair of like-numbered state highways in New York and Vermont in the United States, that are connected by way of the Grand Isle–Plattsburgh Ferry across Lake Champlain. NY 314 extends for 4.73 miles (7.61 km) through the Clinton County town of Plattsburgh from Interstate 87 (I-87) exit 39 to the ferry landing on Cumberland Head. Its Vermont counterpart is a 5.493-mile (8.840 km) loop route off of U.S. Route 2 (US 2) through the Grand Isle County towns of South Hero and Grand Isle that connects to the ferry near its midpoint.
VT 314 was originally designated as Vermont Route F-3 in the late 1920s. The roadway on the New York side was unnumbered until c. 1962, when Cumberland Head Road was designated as NY 314. VT F-3 was redesignated as VT 314 in 1964 to match the designation present at the New York ferry approach. In 2005, a new highway connecting US 9 to the ferry landing by way of the interior of Cumberland Head was completed and opened to traffic as the Commodore Thomas MacDonough Highway. NY 314 was realigned to follow the new highway while ownership and maintenance of its old alignment was transferred to the town of Plattsburgh. The designation of NY 314 east of US 9 was consolidated by July 2014.
