August 19, 1909
The first race is held at the Indianapolis Motor Speedway, now the home of the world’s most famous motor racing competition, the Indianapolis 500. Since 1911, the Indianapolis 500 has been held every year, with the exception of 1917-18 and 1942-45, when the United States was involved in the two world wars. With an average crowd of 400,000, the Indy 500 is the best-attended event in U.S. sports. In 1936, asphalt was used for the first time to cover the rougher parts of the track, and by 1941 most of the track was paved. The last of the speedway’s original bricks were covered in 1961, except for a three-foot line of bricks left exposed at the start-finish line as a nostalgic reminder of the track’s history.
