The goal is to keep repeat offenders in jail a longer period of time.
Now, there is a new addition that will house 240 non-violent inmates.
There are new bunks, eating, exercise and visiting areas.
Sheriff Doc Holladay said a bigger jail translates into a safer community.
"If we can keep more of those non-violent felons for longer periods of time in this facility, our hope is we will reduce the crime rate in our city and in the county."
The entire addition cost $3,900,000.
Little Rock, North Little Rock, Maumelle, Sherwood and Jacksonville will pay two-thirds of the cost.
Counties will pick up the rest.
The new wing will see its first inmates come Thanksgiving Day.
