[1] IL 93 is a rural, two-lane undivided surface road for its entire length.

It travels east and curves north slightly, passing through southern Elmira.

Route 93 continues west through slight hills for the majority of its length, passing only township and county roads.

[3][4] SBI[clarification needed] Route 93 originally ran from Galva to Bradford, with a southern spur to Toulon.

In 1936, Illinois Route 91 replaced the remaining segment west of Elmira to the spur, and then south to Toulon.
