Another short state road, and another that would be moved a few years later. State Road 65 was officially described as “Mt. Vernon north to new State Road 56 by way of New Harmony, Cynthiana, Ft. Branch, and Owensville. (Present State Road 20 extended north from Owensville.)”
The then current SR 20 turned east at Owensville, connecting to SR 10 (US 41) to Princeton, where the original SR 20 became SR 56 on its way to Jasper. The “new” SR 56 mentioned in the official description connected Princeton to Mt. Carmel, Illinois.
