Arizona State Prison Complex – Florence
In 1908 inmates finished building and opened the Arizona Prison at Florence.The chamber was scaffolding above the death row cells that had a trap door for hanging inmates which opened to a room below.Convicts from Florence were a cheap source of labor and the state used them to build roads through the mountains between Bisbee and Tombstone in 1913.Convicts also built a bridge over the San Pedro River and improved the Douglas Highway.[citation needed] The ADC uses a score classification system to assess inmates appropriate custody and security level placement.
