About Johnston City

Johnston City got its start in the late 1800s as a lively railroad and coal mining hub in southern Illinois. Today, it has settled into a quiet, close-knit community in Williamson County with a classic small-town feel. Located right off Interstate 57, the town makes daily commuting simple, with the shopping, dining, and healthcare of Marion only a short drive down the road. Between relaxing afternoons at Arrowhead Lake and easy access to regional amenities, Johnston City offers an affordable, comfortable setting for newcomers looking for a friendly place to live.
