 The three routes never actually reached the village, however, as all three designations ended at an intersection with US 20 (the Cherry Valley Turnpike) west of the village limits and west of the village center.NY 20SY was assigned in 1951 as an alternate route of US 20 in the Syracuse area.While US 20 bypassed the city of Syracuse to the south, NY 20SY veered north to serve Downtown Syracuse and the eastern and western suburbs of the city.
