McLean County, Ill.
Created by: William Coltharp and Tom Healy
Introduced in: 1985
McLean County, located at the center of the state, is Illinois’ largest county. At the intersection of three interstate highways and multiple rail service lines, the county is home to major financial institutions including State Farm Insurance and Country Companies, and the state’s oldest public university, Illinois State University, as well as Illinois Wesleyan University.
The county’s prominence on the state map, both in size and location, make the outline of McLean County’s boundaries identifiable to a large portion of the state’s population. Its rich, fertile soil is some of the most
productive in the world and the topsoil layer reaches as deep as 48 inches.
The county logo pairs the county’s outline with the color green, representing its agricultural character. The logo also includes the silhouette of the old courthouse dome, built in 1903.
Bill Wasson, county administrator, assisted.
