Associated Bank has moved on to its next stage of renovations to its downtown Milwaukee office tower, about a year out from the scheduled move-in of about 400 employees. Green Bay-based Associated purchased the 28-story Milwaukee Center building, at 111 E. Kilbourn Ave., in 2016. It renamed the building to the Associated Bank River Center, and has commenced major renovations. The tower is connected to the company's private client services building, the Saint Kate hotel and others.
