About 250 Milwaukee-area construction workers will help pour 10,000 cubic yards of concrete that will be delivered Friday and Saturday, March 27 and 28. To prepare for the event, some street and sidewalk closings will occur. Construction of the 1.1 million-square-foot Northwestern Mutual Tower and Commons is scheduled for completion at the end of 2017.
