The Port Kent and Hopkinton Turnpike was a 19th-century toll road in the North Country of New York in the United States.
It began in the town of Hopkinton and ended at the hamlet of Port Kent, located on the western shore of Lake Champlain.
It headed eastward on what is now Port Kent and Red Tavern Roads through Saint Regis Falls to the town of Duane.
From Franklin to Au Sable Forks, the Port Kent and Hopkinton Turnpike used a series of roadways that are now primarily local roads.
The idea of constructing a highway leading southward from St. Lawrence County was first conceived as early as the beginning of the 19th century.
On April 16, 1827, a team of three surveyors were commissioned to determine a routing for a new highway leading from Hopkinton, a town in northeastern St. Lawrence County, to Lake Champlain.
