The simple gurney replaces the electric chair as the state's primary method of execution.
It cost $180,000 to build and is in the same building that housed the electric chair known for years as "yellow mama."
Alabama's prison commissioner said the new chamber has three large viewing rooms, allowing for more witnesses than the old chamber.
The first use of the new death chamber could come at 6 p.m. on Oct. 17. That's when Donald Dallas is supposed to die for the kidnapping, robbery and murder of a Millbrook, Alabama woman in 1994.
