Background
Atlanta Motor Speedway (formerly Atlanta International Raceway) is a track in Hampton, Georgia, 20 miles (32 km) south of Atlanta. It is a 1.54 mi quad-oval track with a seating capacity of 111,000. It opened in 1960 as a 1.5 mi standard oval. In 1994, 46 condominiums were built over the northeastern side of the track. In 1997, to standardize the track with Speedway Motorsports' other two 1.5 mi ovals, the entire track was almost completely rebuilt. The frontstretch and backstretch were swapped, and the configuration of the track was changed from oval to quad-oval. The project made the track one of the fastest on the NASCAR circuit.
