AT&T Stadium — sometimes called "Jerry World" — is one of the largest stadiums in the world by seating capacity. Located at 1 AT&T Way, Arlington, TX 76011, it seats approximately 80,000 with a capacity that has exceeded 100,000 for special events. It is home to the Dallas Cowboys NFL franchise.
The stadium features a retractable roof (which will almost certainly be closed for comfort during summer World Cup matches) and a massive HD video board spanning the length of the field.
Critical geography note: AT&T Stadium is in Arlington, Texas — not in Dallas proper. Arlington is a city between Dallas and Fort Worth, roughly 20 miles west of downtown Dallas and 20 miles east of downtown Fort Worth. There is essentially no public transit connecting Dallas/Fort Worth to Arlington.
Arlington has invested in a new event-day transit service that will shuttle fans from Dallas DART rail stations to the stadium — check arlingtontx.gov for World Cup shuttle service specifics.
