Located in College Station, Texas, the Texas World Speedway opened in the fall of 1969. It was built to be almost exactly like the Michigan International Speedway, which placed it among the only eight superspeedways in the U.S. This speedway held many major races including the Texas 500 and Alamo 500. It had its last major race in 1981. The National Auto Sport Association, the Porsche Club of America, driving schools, and many other amateur racing clubs and businesses also used this speedway. The speedway was officially closed in the fall of 2017.
