Miller Park is a ballpark located in Milwaukee, Wisconsin. It is home to the Milwaukee Brewers and was built as a replacement for Milwaukee County Stadium. The park is located just southwest of the intersection of I-94, US-41, and Miller Park Way (WIS-341). The title sponsor is the Miller Brewing Company. Miller's contract with the stadium was for $40 million, and runs until 2020. The park, completed in 2001, features North America's only fan-shaped convertible roof, which can open and close in less than 10 minutes. Large panes of glass allow natural grass to grow.
