Incarcerated women to move into new Rapid City prison to alleviate overcrowding

Incarcerated women will start moving into a new $87 million prison in Rapid City next month, a South Dakota Department of Corrections spokesperson confirmed this week.

The medium-security prison will be the state’s second for women. The South Dakota Women’s Prison in Pierre has operated beyond its capacity for years, with dozens of people serving their sentences at the Hughes County Jail or in halfway house facilities.

The new prison in Rapid City, which was approved by state lawmakers in 2023, will add 288 beds to the state’s capacity. The Department of Corrections will begin transferring women there next month, according to spokesperson Michael Winder, who said the exact date of full operations won’t be released for security reasons

The prison includes a work release area, a mother-infant building that lets new moms stay in a home-like environment with their babies, a vocational training facility to be staffed by instructors from Western Dakota Technical Institute and 96 beds for chemical dependency treatment.

The majority of the women held in South Dakota prisons are incarcerated on nonviolent drug charges, and 97% have a substance use disorder diagnosis.

“Drug addiction is a disease that must be treated,” Corrections Secretary Nick Lamb said at Friday’s ribbon cutting, adding that “Through dedicated treatment space and the therapeutic community, women will receive the counseling support and skills that they need to break the cycle of addiction and successfully return to their families and communities.”

The mother-infant program mirrors one launched a few years ago in Pierre. 

Mothers who qualify under security guidelines stay in a group home separate from the main prison facility with other women and children for the first few years of their child’s life. The program was launched by former Corrections Secretary Kellie Wasko and was championed by Lamb in his first public conversations with lawmakers on the state’s budget committee during the 2026 legislative session.

At Friday’s event, Gov. Larry Rhoden said family connections and parenting skills are key factors in rehabilitation. He framed the program as an extension of a commitment to the well-being of South Dakota families.

“This program gives mothers and their children the opportunity to build that foundation from the very beginning,” Rhoden said.

Rhoden also called out the vocational training, drug treatment and work release programs as vital to rehabilitation — and to public safety by extension. The state recently broke ground on a new $650 million men’s prison in Sioux Falls, which is set to replace the state penitentiary and is also designed to expand programming and rehabilitation.

When combined with pending policy recommendations from the state’s correctional rehabilitation task force, Rhoden said, the new prisons will help improve public safety statewide by reducing the number of people who return to prison within a few years of their release. 

“At the end of the day, every person in our corrections system is a human being,” Rhoden said. “They are sons and daughters. They are mothers and fathers. People who’ve made mistakes but also have the capacity to change.”

Winder, the corrections spokesman, told South Dakota Searchlight that staff will spend the next few weeks training at the new facility in preparation for the arrival of inmates in August.

The state hired Eric Aldridge to serve as warden in March. Aldridge, who came to South Dakota after a stint as warden of a medium-security women’s prison in Troy, Virginia, said Friday his goal is to “to facilitate an environment, an atmosphere, a culture where people learn, they grow, they heal, and where people develop through dignity and respect.”
