Not everybody is happy about plans for a million-square-foot warehouse near Interstate 94 in western Wisconsin. Many people living in Roberts, a village in St. Croix County, have voiced their opposition. They say Project Mallard will create traffic congestion, but village officials say the big structure will also create about 800 jobs. Roberts has just over 16 hundred residents. Village leaders haven’t said what company wants to build the warehouse. If it is approved at a meeting later this month, ground could be broken in the fall, and the building would be open late in the summer of 2022.
