CRYSTAL LAKE – A state board is expected Tuesday to decide whether it will reconsider Mercy Health System’s proposal to build a $115 million, 70-bed hospital in Crystal Lake.

The health care provider, based in Janesville, Wis., has been trying for nearly a decade to get permission from the Illinois Health Facilities and Services Review Board to build a hospital at Three Oaks Road and Route 31.

In the past 19 months, the review board twice has rejected Mercy’s proposal. However, an administrative law judge recommended that the review board take another look at both Mercy’s plan and a competing proposal from Centegra Health System to build a hospital in Huntley because of a clerical filing error.
