Texas Worl Speedway was built in 1969 and is one of only seven superspeedways of two miles (3 km) or greater in the United States, the others being Indianapolis, Daytona, Pocono, Talladega, California, and Michigan. TWS is located on approximately 600 acres (2.4 km²) on State Highway 6 in College Station, Texas. There is a 2-mile (3 km) oval, and several road course configurations. The last major race occurred at the track in 1981. The track is still used by amateur racing clubs such as the SCCA, NASA, driving schools and car clubs, as well as hosting music concerts and the like.
