Chicago-based Rush University Medical Center is declaring the end of the first phase of a $1 billion campus renovation with the opening this month of its orthopedic building. The $75 million, 220,000-square-foot building is one of the largest orthopedics facilities in the Midwest and is a key component of the renovation project, according to the hospital. The five-story structure, slated to open Nov. 16, will offer comprehensive outpatient care.
