New in 2025, The Dome at America’s Center in St. Louis, MO will see playoff racing for the first time. However, the city of St. Louis is no stranger to regular season Supercross racing, having hosted 26 Monster Energy Supercross races since 1996 and has been a consistent host market on the schedule since. The venue has gone through several name changes over the years, but The Dome at America’s Center has long been lauded as having the best “dirt” in the world. The domed stadium and adjacent exhibition hall combined feature an impressively large footprint with which the SMX master track builders will use to create a one-of-a-kind “motocross-inspired” SMX World Championship caliber track.
