When NY 348 was originally assigned as part of the 1930 renumbering of state highways in New York, it began in West Chazy and ended in the village of Champlain.

At this junction, NY 348 turned northeast along Fiske Road, crossing over the Little Chazy River and nearby Bayington Brook.

Bending further northeast through the town of Chazy, the route paralleled the Delaware and Hudson until reaching a crossing with the Adirondack Northway (I-87).

The 6.34 miles (10.20 km) alignment was 14 feet (4.3 m) wide and to be constructed with stones approved by the state with sand and limestone filler.

The state engineer estimated that the improvement of the road would cost $58,250 (1907 USD), and a contract was let on September 19, 1907 to Jeremiah T. Finch, who commenced work on the new roadway in October of that year.
