Maddox declined to list potential investors in the project, but he said it included both active and retired professional athletes. The sports complex itself will cost roughly $50 million. “But what we were wanting was a theme for the entire development.” We could’ve done a bunch of one-off things and put a hotel in here or one or two restaurants, that kind of thing,” Maddox, president of Maddox Companies, told Knox News. The currently unnamed complex will feature 12 turfed fields, indoor arenas, half a dozen or more hotels, restaurants, retail stores and hundreds of apartment units, all privately funded. Starting this spring, Maddox will begin constructing a multimillion-dollar sports complex unlike any other in the region, a game-changing setup that will make Knoxville a go-to place for youth sports. Knox County developer Steve Maddox has been buying up property off Interstate 40 at Watt Road near the Loudon County line in West Knox County for years, and he’s ready to get to work.
