Indy 500. 3.2 Million Bricks!
How a 1909 disaster, 63 days, and 3.2 million bricks built the most kissed surface in American sports.
Five people died on the opening weekend of the Indianapolis Motor Speedway in 1909. The track founders had two months to fix it before everything they had built collapsed. Their answer: 3.2 million bricks, hand-placed in 63 days. This is how the Brickyard got its name and why three feet of those bricks still remain.
When the Indianapolis Motor Speedway opened in August 1909, the racing surface was a mix of crushed limestone, gravel, and tar. Within two days, the surface broke apart at racing speed. A wheel came off Wilfred Bourque's car and he died when it hit a fence post. Charlie Merz's car shredded a tire and flew into the crowd, killing two spectators. By the end of the opening weekend, five people were dead, including the two paying customers.
The AAA threatened to ban racing at IMS. Indiana's lieutenant governor wanted racing outlawed across the entire state. The four Speedway founders had two months to find an answer or lose everything.
Their answer was bricks. 3.2 million of them. Laid by hand in 63 days. Plus a 33-inch concrete wall to protect the spectators. The final brick, laid on December 14, 1909, was made of solid gold.
