Work is officially underway for St. Louis’ highly anticipated expansion of the America’s Center Convention Complex expansion project. Regional leaders came together in mid-May in downtown St. Louis to celebrate the groundbreaking of the project, known as AC Next Gen. Last updated in 1995, the $210 million facelift will bring a new 75,000-square-foot exhibit hall and new entrance on Dr. Martin Luther King Jr. & 9th Streets, infused with daylight, featuring tall ceilings and networking lounges.
