Advocate Aurora has dual headquarters in Milwaukee and Downers Grove, Ill.
The entire facility will be 185,000 square feet and have 10 new patient beds and an eight-bay emergency department.
The project was announced in 2020 and was supposed to begin construction in 2021, but was delayed by the COVID-19 pandemic. It is expected to open in 2024.
Aurora Medical Center in Oshkosh (Wis.) will partner with the hospital to provide some services.
