Where did the bricks come from whats the companies name to build the Indianapolis Speedway?

The Indianapolis Speedway's "Yard of Bricks" is the roughly 3' wide strip of bricks that marks the start/finish line at the track

• 'yard' refers literally to it being a YARD wide.

At least, it is only a yard wide today. Back in 1909, the track had originally been paved in 3.2 million bricks. Some 90% of these had been made by the Wabash Valley Clay Company of northern Indiana. Over the years, various repairs and resurfacing projects replaced layers of brick with asphalt, and today, only "The Yard" remains.
