 After World War II, Route 30, which had followed the course northeast that 30A does today, was realigned to its present course and the intersection reconfigured into a Y with Route 43 following a new road, parallel to a former rail corridor, that forked off south of the original intersection; the portion that had led west from the intersection to the realignment was vacated.In 1960 Route 43 was truncated to end at its junction with Route 30 in Schoharie; the portion north of the Route 30 intersection was made part of Route 30A, newly created at the behest of the Fulton County Automobile Club.This configuration of the intersection necessitated that traffic on southbound 30 not only stop at the bottom of the hill but turn left just before doing so.
