After more than three years and several location changes, Nemours Foundation will finally break ground on its children's hospital in February. Nemours officials said that groundbreaking for the hospital and children's clinic will be held on Feb. 25 at Lake Nona's medical city complex. The hospital, which will be built in a complex near the University of Central Florida's College of Medicine and the Burnham Institute for Medical Research, will likely open in the second half of 2012.
