Menomonee Falls-based Bradley Corp. recently began construction of a 190,000-square-foot plant at N106 W13500 Bradley Way, Germantown, in the Germantown Business Park. The plant is expected to be operational by early 2012. About 100 employees will work in the facility. It will replace the company's plant at 7020 W. Parkland Court, Milwaukee, which will be closed. The company said the new plant may be expanded in the future to more than 300,000 square feet.
