OSF HealthCare said Wednesday it plans to replace its Ottawa hospital as part of a multi-step plan to transform its operations in the Illinois Valley region.

The new inpatient hospital will be built across the street from OSF HealthCare Saint Elizabeth Medical Center, which was built in the early 1970s and is “at the end of its useful life,” according to a statement from the health system.

“When the new hospital is built, it will be reimagined as levels and types of services offered are realigned throughout the I-80 corridor,” said August Querciagrossa, CEO of the western region for OSF HealthCare. “Our intent across all our I-80 communities is to ensure current and future generations have access to care locally.”

The new site will include a 26-bed inpatient behavioral health unit, 12 medical/surgical beds, a surgery suite, emergency services, diagnostic imaging and outpatient care services.

Primary and specialty care clinics will include cardiovascular care, general surgery and OB-GYN services.

OSF expects to file an application later this month with the Illinois Health Facilities and Services Review Board, with the goal to open the hospital by late 2027.

The health system did not provide an expected cost for the project, saying that total investment in the community will be “more than $180 million.”

Additionally, the health system said OSF Saint Elizabeth-Peru, which is set to reopen in April, will serve as the “hub hospital” in the region. The site will have 45 medical/surgical beds, 8 intensive care unit rooms and 11 obstetric rooms to support the regional birthing center. It will also have surgery and procedure rooms, emergency services, diagnostic imaging and outpatient care services.

The Fox River Cancer Center in Ottawa will expand cancer care too, as part of a network with the OSF Cancer Institute in Peoria and the Patricia D. Pepe Center for Cancer Care at OSF Saint Anthony Medical Center in Rockford.
