GREENFIELD, Wis. (CBS 58) -- One of Milwaukee's signature companies, Rockwell Automation, announced an expansion plan Tuesday, Nov. 18. 

The company will build what it calls a "Greenfield manufacturing site" in southeastern Wisconsin. 

The announcement did not include details like where the plant will be located or how many people will work there. 

But what we do know is that it will be big with more than one million square-feet of manufacturing and warehouse space. 

This is part of Rockwell's $2 billion investment in plants, digital infrastructure and talent.
