Indianapolis Motor Speedway has been around since 1909, and the historic track has seen plenty of renovation over the last 108 years.

If you’ve ever been curious to see how Indianapolis Motor Speedway has changed over the years, president J. Douglas Boles posted a picture showing the various layers of the track from repaves.

The track also shared a graphic showing when each layer was added and why.

It’s fascinating how the original surface in 1909 was creek gravel and limestone. The famous bricks were laid later that year, and then asphalt was later added decades later.
