Mid-State Correctional Facility is located on the grounds of Fort Dix, the military base in Burlington County. The 696-bed prison, which occupies 12.24 acres, opened in 1982, when the New Jersey Department of Corrections entered into a leasing agreement with the federal government requiring that unique operating procedures are followed on the military base. The State of New Jersey became the owner of Mid-State in August 2004. The facility, which had been closed since June 2014, reopened in April 2017. Mid-State is the first licensed, clinically driven drug treatment program provided by the NJDOC.
