The state highway serves a corn-and-soybean-growing region in Macon County and Piatt County. Roads such as IL-105 carry corn and soybeans to the refineries of Decatur for the manufacture of commodities such as soybean oil and corn syrup.

SBI Route 105 was what Illinois Route 104 is now from Meredosia to Quincy from 1924 thru 1937. In 1945, the number was reused on former Illinois Route 47 north of Decatur. This is the current routing for Illinois 105.[2]
