 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 .
