The Towers Jail was built in 1982, designed as a 360-cell facility with six tower units. There are four pods in each tower, and each pod contains housing areas with general-purpose day rooms, and bathroom/shower areas. The jail also contains a fully staffed and equipped medical clinic, a non-denominational chapel for religious services, and classrooms for educational, drug rehabilitation, and life-skills programs. Additionally, there are three outside areas for recreation.

The jail houses multi-classification adult male inmates; the population is approximately 800 inmates.
