 The first set of posted routes in New York were assigned in 1924. Two of the routes assigned at this time were NY 6, a north – south route extending from the New York City line to the Canadian border, and NY 30, another north – south route connecting NY 6 in Mechanicville to the Vermont state line west of Fair Haven. NY 6 left Albany on modern NY 32 and followed it to Mechanicville, where NY 6 veered westward on what is now NY 67 and NY 30 picked up the current alignment of NY 32. NY 30 continued north on modern NY 32 to Glens Falls, at which point it went east to Hudson Falls via Warren and River streets. It headed northward from there to Vermont on modern US 4. From Mechanicville to Schuylerville, NY 30 utilized the alignment of legislative Route 44. By 1926, NY 30 was rerouted north of Whitehall to continue north toward the Canadian border. The old alignment of NY 30 between Whitehall and Vermont was not assigned a new number. Meanwhile, an alternate route of NY 6 on the east side of the Hudson River between NY 5 (now US 20) in East Greenbush and NY 6 in Waterford was designated as NY 6B by 1926.
