The first automobile race Speedway, 1909
The Indianapolis Motor Speedway is an automobile racing circuit located in Speedway, Indiana, Indianapolis in the United States. It is the home of the Indianapolis 500 and the Brickyard 400, and formerly the home of the United States Grand Prix.
Constructed in 1909, it is the second purpose-built, banked oval racing circuit after Brooklands and the first to be called a ‘speedway’. The first official racing began on the 19th August, 1909.
Considered relatively flat by American standards, the track is a 2.5-mile-long (4.0 km) rectangular oval with dimensions that have remained essentially unchanged since its construction. It has two 5⁄8-mile-long (1,000 m) straightaways, four geometrically identical 1⁄4-mile (400 m) turns, connected by two 1⁄8-mile (200 m) short straightaways, termed “short chutes”, between turns 1 and 2, and between turns 3 and 4.
Extra Note: Indianapolis businessman Carl G. Fisher first envisioned building the speedway in 1905 after assisting friends racing in France and seeing that Europe held the upper hand in automobile design and craftsmanship.
