Construction firm Robins & Morton has begun work on the $150 million vertical expansion at Huntsville Hospital Madison Street Tower in Huntsville.

The 5-story, 154,000-square-foot project will add 120 beds as well as a cardiothoracic intensive care unit, a neuro intensive care unit for neurosurgical and stroke patients, and three floors of new acute medical space. Additionally, a new and improved emergency department vehicle entrance will be included.

“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 Huntsville Hospital Health System.

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 881 currently.

“This project marks another chapter in our longstanding relationship with HH Health System as we work to deliver this important project for our community,” Robins & Morton Division Manager Mitch Coley said. “The hospital’s tower expansion will have a lasting, positive impact for many years ahead.”

Robins & Morton, the general contractor responsible for constructing the Madison Street Tower in 2006, is once again leading the project. Chapman Sisson Architects, who designed the original structure built by Robins & Morton in 2006, is serving as the architect for the project.

The project is scheduled for completion in 2027.
