HSHS St. Elizabeth's Hospital in O'Fallon, Illinois, is planning a $116 million renovation and expansion project. The work will expand the emergency department, increase inpatient nursing capacity, and add an outpatient surgery center, advanced imaging options and medical office space.
Hospital President and CEO Chris Klay announced the plans Sept. 15. "It is incredible that in the year we celebrate 150 years of existence, St. Elizabeth's Hospital remains vibrant and positioned for growth as demonstrated with these new expansions," Klay said in a release.
He added: "Our community deserves access to high-quality care close to home, and this project ensures we can deliver that for generations to come."
The project will modernize 32,000 square feet of space at the hospital and add 19,000 square feet of clinical space. The construction will add a 70,000-square-foot medical office building on the hospital campus. The work also includes adding four operating rooms, two procedure rooms, 32 private inpatient medical/surgical rooms, eight emergency department treatment rooms, a new cafeteria, an expanded waiting area and more security features.
Construction on the outpatient surgery center and the medical office building began this summer and is expected to be completed by October 2026.
