A small preppy community by the Henry Hudson Bridge, spanning from the Hudson river's edge to and ending with the hill by Riverdale Avenue. Once down the hill you enter KINGSBRIDGE!!!!! The crappy drug infested area surrounding Manhattan College is called Kingsbridge and is commonly mistaken for Riverdale. Riverdale is nice; we don't have welfare families living up here and, we have good educations.

one of the three hill schools, the other two being fieldston and horace mann. riverdale is by far the best of all three schools. whereas at fieldston they get high, at riverdale the kids get drunk. academics are comprable to horace mann, and better than fieldston. riverdale kicks major ass.
i go to riverdale. i rock this world.
