Which Way to Which Highway?

US 136 in Fulton County, Illinois

The confusing concurrence of US 24, US 136, and Illinois 100 in Fulton County requires a careful reckoning of which highway is going in which direction.

I haven't seen this type of directional assembly anywhere else in Illinois. It's at the southernmost US 24-US 136-Illinois 100 intersection, seven miles west of Havana in west-central Illinois.
