The Illinois River valley serves as the industrial and geographic anchor of this Central Illinois landscape, connecting manufacturing centers like Peoria, Pekin, and East Peoria. The 1958 field data, revised through 1980, captures the region's transition into the interstate era, with Interstate 74 and Interstate 55 bisecting the fertile glacial till plains. Outside the urban hubs of Bloomington and Champaign, the map reveals a dense network of smaller rail-oriented towns such as Chenoa and Gibson City, which flourished as collection points for the surrounding grain belt.
