In 1924, Warren Street in
Glens Falls and River Street in
Hudson Falls became part of
NY 30, a highway that initially extended from
Mechanicville to the
Vermont state line near
Fair Haven by way of Glens Falls and
Whitehall. It was realigned by 1926 to continue north from Whitehall toward the
Canadian border. In 1926, the portion of NY 30 between Glens Falls and Whitehall was included in the new
US 4, which began in Glens Falls and continued east from Whitehall into Vermont by way of NY 30's former routing. It was rerouted to follow its modern alignment south of Hudson Falls as part of the
1930 renumbering of state highways in New York. US 4's former routing between Glens Falls and Hudson Falls became part of NY 32B, a new route assigned in the renumbering that continued south to
NY 32 in
Northumberland by way of an
overlap with US 4. NY 32B was gradually truncated as time went on. In the early 1940s, NY 32B was cut back on its east end to its junction with US 4 in Hudson Falls, eliminating its lengthy overlap with US 4 along the
Hudson River. The route would have been severed from its parent, NY 32, as a result; however, NY 32 was extended northeastward along
US 9 from
South Glens Falls to NY 32B in Glens Falls by this time. On January 1, 1949, NY 32 was extended east to US 4 in Hudson Falls by way of Warren Street, Boulevard, and Feeder Street. The resulting overlap between NY 32 and NY 32B along Warren Street from downtown Glens Falls to Boulevard remained in place until when NY 32B was truncated on its western end to the eastern terminus of the overlap. NY 32B ceased to exist altogether when the portion of NY 32B east of the newly constructed Quaker Road was incorporated into the new
NY 254. ==Major intersections==
