A new addition to the Star City skyline is on the horizon, as Carilion Roanoke Memorial Hospital unveils progress on its Crystal Spring Tower.

Another step forward for the state-of-the-art expansion at Carilion Roanoke Memorial Hospital.

Carilion Children’s patients are leaving their mark on a historic build — the Crystal Spring Tower.

As progress is made on Carilion’s Crystal Spring Tower build, there’s also progress happening inside the walls.

The parking garage will feature 600 spaces, available for both Carilion patients and staff as well as the public.

The $400 million, 400,000 square foot addition will feature an underground parking garage, additional emergency rooms, cardiovascular beds and cutting-edge technology.

Construction crews have erected a 240-foot tower crane that will be critical in building the new $400 million, 500,000 square foot Crystal Spring Tower expansion.

We reported in May about the huge expansion project, investing $300 million and adding three new buildings to Roanoke Memorial Hospital. Carilion vice president of facilities and operations Marty Misicko walked 10 News through the latest updates to the hospital's biggest project yet. The most visible change is noted in new renderings: the Crystal Spring Tower that's taking over the old tennis courts, pushed much further back off the road. The plan has also grown from the 400,000 square feet we reported in May to at least 454,000 square feet. I think that's a frustrating piece for anybody that's going to visit there, Misicko said.
