One of the primary competitors of BROOKFIELD SQUARE was -and is- SOUTHRIDGE MALL. It was dedicated in September 1970 and was Wisconsin's first 2-level, fully-enclosed retail complex. Today, with a GLA of 1,177,000 square feet, it is the Dairy State's second-largest mall. As a matter of note, FOX RIVER MALL, in the Fox Cities area, is the largest.
