World's Longest
Single-Span
Roof
Dallas Cowboys Stadium
Arlington, Texas
When this new, 80,000-seat home of NFL’s Dallas Cowboys opens in 2009, the world’s longest single-span roof will be part of the 2.3-million-square-foot stadium.
The 14,100-ton, structural steel, domed roof is supported by two 17-foot-wide by 35-foot-deep arch box trusses spanning 1225 feet. The 660,800-square-foot retractable roof will feature a 256-feet wide by 410-feet long roof opening. A rack-and-pinion drive system will open and close the two bi-parting mechanized roof panels in less than 12 minutes.
Both end zones will feature 180-foot-wide by 120-foot-high glass operable doors that will open in 18 minutes, making them the tallest glass retractable doors in the world.
