I didn’t get quite far enough with this run to get to my next point of interest, but that’s the one I’m going to talk about anyway. (The Illinois River is coming up, so that’s the reason for the southward turn.) U.S. 24 originally ran from Kansas City, MO, to Pontiac, MI, though it now extends westward as far as central Colorado. In Illinois, it connects Quincy and Peoria along what used to be the stagecoach route between the two cities before heading straight east into Indiana.
