Dirty job: How NASCAR's Bristol Motor Speedway was converted from concrete to clay
Fox News
Bristol Motor Speedway has been converted into a dirt track for the second year in a row and the head of operations, Steve Swift, shares the details on how it was done.
The project is on the same scale as when NASCAR converted the Los Angeles Memorial Coliseum into a paved quarter-mile track for the season-opening Clash in February, and the two-month process involves a lot more than just tossing some dirt onto the concrete.
Steve Swift, vice president of operations for Bristol owner Speedway Motorsports told Fox News Autos that they’re using the same red clay they shipped in from four locations for last year’s event, but have improved the blend to make for a more uniform surface.
