In March construction started on a $150 million tower expansion at Huntsville Hospital.

The five-story, 154,000-square-foot project will add 120 beds, a cardiothoracic intensive care unit, a neuro intensive care unit for neurosurgical and stroke patients, three floors of acute medical space and a new emergency department vehicle entrance.

“Expanding the Madison Street Tower will give us the space to meet the advanced health care needs of North Alabama and southern Tennessee for decades to come,” said Jeff Samz, president and CEO of the Huntsville Hospital Health System.

Additionally, the project will convert 70 existing patient rooms from double occupancy to single occupancy. When the expansion is complete the hospital will have a total of 931 patient beds, up from its current 881 beds.

Robins & Morton, which built the Madison Street Tower in 2006, is serving as the general contract on the project, with Chapman Sisson Architects providing architectural services.
