The last ten years have been a renaissance for baseball stadium construction�a trend that doesn't look likely to stop just yet�and four of the new parks are on the cutting edge, featuring dramatic retractable domes. Phoenix, Seattle, Houston and Milwaukee serve as the sites for these parks which all feature steel and concrete seating bowls covered by moving steel roofs. While each stadium has its quirks and features, all operate on the same basic concept: motorized bogeys slide 600 ft long truss panels back and forth to open and close the stadiums. Engineers on each project faced challenges because of differing climates and client demands, not to mention that there is little precedent in North America for building stadiums with retractable domes and the only other one on the continent is Toronto's Skydome. All four U.S. stadiums stay in step aesthetically with other modern parks (typified by Baltimore's Camden Yards) with generous amounts of exposed structural steel and brick exterior facades.
