More than 195 drivers have won a Cup Series race since NASCAR started in 1948, but who has won the most?

For the second year running the half-mile oval in Tennessee has been temporarily turned into a dirt track for its spring NASCAR weekend.

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.

After laying down three to four inches of sawdust to protect the pavement, it took 2,300 truckloads to move the 23,000 cubic yards of clay into the stadium.
The depth of the clay ranges one to two feet on the straights to six to 12 feet in the turns and the design of the banking has been modified using lessons learned at the first race. Instead of a nearly constant 17-18 degree grade they now feature a progressive design that goes from 16 degrees on the inside line to 20 degrees at the wall.
Swift said the hope is that this will create multiple grooves and that the steeper outside line will give the cars more to press against as they slide through the curves, which should increase their speed.

The track hosted the Karl Kustoms Bristol Dirt Nationals for modified cars in March to shake down the surface before the NASCAR Truck Series and Cup Series comes to town Easter weekend. Two weeks later the World of Outlaws sprint car series will race at the track and the cleanup begins as it is returned to concrete for the September NASCAR playoff weekend.
Swift said that will take six weeks to clean things up, quite literally. Over the course of the race weekends, clay gets kicked up into the stands and onto the roofs of the suites at the top of the facility. After removing the track surface, they start pressure washing at the top and work their way down until there’s not a spec of clay left inside.

They’ll be storing it again, however, with the expectation of another dirt race in 2023. It hasn’t been confirmed, but Swift said the spectacle has increased demand for tickets and interest in the event.
