INVESCO Field at Mile High was constructed in 1999 to replace the former Mile High Stadium. Providing 1.7 million square feet of space, the new INVESCO Field at Mile High can seat 76,125 spectators. The old stadium was almost as large, but the space wasn't used as efficiently and the stadium was outdated. The new INVESCO Field at Mile High has wider concourses, wider seats, more restrooms, more elevators, more escalators, and better accommodations for people with disabilities.
INVESCO Field at Mile High was designed and built by Turner/Empire/Alvarado Construction and HNTB Architects, in association with Fentress Bradburn Architects and Bertram A. Bruton Architects. Many other companies and designers, engineers, and construction tradesmen worked on the Broncos' new stadium.
Political parties traditionally use lavish decorations to impress and inspire prospective voters. To prepare INVESCO Field at Mile High for the nomination acceptance speech by Democratic presidential candidate Barack Obama, Democrats created a dramatic set that mimicked the look of a Greek temple. A stage was constructed at the 50-yard-line, the midpoint of INVESCO Field. Along the rear of the stage, designers constructed neoclassical columns made of plywood.
