 From Albany to Clifton Park and from South Glens Falls to Riparius, modern US 9 was part of Route 25.At Riparius, Route 25 met Route 22, which utilized what is now US 9 from Riparius to Elizabethtown and from Keeseville to the town of Champlain.While modern US 9 travels directly from Elizabethtown to Keeseville and bypasses Rouses Point to the west, Route 25 used current NY 9N between Elizabethtown and Keeseville and served Rouses Point via modern NY 9B.
