The seat of Johnson County, Cleburne is found at US 67 and Hwy 174, south of the Dallas-Fort Worth Metroplex. Its origin and growth can be attributed to its role as a crossroads and transportation center.
After 1945 proximity to the Dallas-Fort Worth region resulted in substantial growth in Cleburne. By 1990 the city had a population of 22,205, forty manufacturing facilities, a new regional hospital, and a community college extension center. A major area employer has been the Comanche Peak Nuclear Power Station in nearby Glen Rose.
