Atlanta Motor Speedway is an oval circuit, located south of Atlanta. The circuit is a quad oval, and has a seating capacity of over 125,000 people. Originally it opened in 1960 as a 1.5 mile circuit, however in 1997 the circuit was totally rebuilt. This included a change in the track to make it a quad oval, which increased the length by 0.04 miles. Atlanta is possibly the fastest circuit on the calender, with average qualifying speeds of over 190mph. Due to the location of the track, it had to be used as a shelter for hurricane victims, and over the years has been hit by bad weather.
