SPD, collaborating with HKS Architects and the Dallas Cowboys, created the comprehensive program of exterior and interior signage and amenities for the AT&T Stadium. The multifunctional stadium includes conference facilities, offices, retail establishments, restaurants and other food services, a museum, parking services, sponsorship opportunities, and other public services. At 2.3 million square feet, the stadium holds 80,000 to 100,000 spectators and is the largest NFL stadium in the USA. SPD also created the AT&T Cotton Bowl office space at the Stadium.
