  • Miller Park Roof Information

    Undoubtedly, Miller Park's most unique feature is the roof. The only fan-shaped convertible roof in North America guarantees perfect conditions for every game. The 12,000-ton, seven-panel roof opens and closes almost silently in just 10 minutes.

    Three panels, each as big as the roof over the Bradley Center in downtown Milwaukee, move over a fixed panel on the third base side. Two more panels move over a fixed panel on the first base side. The roof panels pivot on a fixed point behind home plate, and are each powered by a 60-horsepower engine, or "bogey," that moves along a semi-circular rail system, or "track beam," about 150-feet above the exterior outfield wall.

    Inside, the roof reaches 200 feet above the playing field. Outside, the highest arch towers 30 stories, the newest fixture in Milwaukee's skyline.
