New York State Route 373 (NY 373) is a short state highway in Essex County, New York, within Adirondack Park. It begins at U.S. Route 9 (US 9) and proceeds eastward, ending at a ferry landing on Lake Champlain. It intersects two county routes, several local roads, and a reference route—NY 912T—which connects it with US 9. NY 373 is the only connector between US 9 and the hamlet of Port Kent and the ferry that serves it.
The hamlet of Port Kent and the connecting road were originally built in 1823. The village was planned to act as a source of labor for iron manufacturing and to provide for the industrial needs of Essex County. The hamlet grew and eventually became connected to Burlington, Vermont, via an hour-long ferry across Lake Champlain. The road that accessed Port Kent originally began in Keeseville, but became part of the longer Port Kent and Hopkinton Turnpike in the 1830s. The highway that is now NY 373 was also designated as part of the Theodore Roosevelt International Highway in 1919.
When NY 373 was designated in 1930, a small portion of it was maintained by the town of Chesterfield. This section was turned over to the State of New York during a maintenance swap with Essex County in 1985.
