The way to best illustrate the early history of Dover International Speedway would be to look at the list of winners in the track's early years as a site for Cup racing.

From 1969 through '80, 21 of the 22 Cup races at Dover International Speedway were won by drivers who either already had or would go on to win championships in NASCAR's top series.

The names of those winners are part of the fabric of the sport -- Richard Petty, Bobby Allison, David Pearson, Cale Yarborough, Benny Parsons and Darrell Waltrip. Allison and Petty rank first on the all-time winner's list at Dover International Speedway with seven victories apiece.

About 3,200 seats were added to the facility in 1982. Each following year until 1998, more seats were added.

In 1995, the track's surface was switched to concrete -- making it the first all-concrete superspeedway in the sport. The unique look of the white concrete surface still makes Dover's appearance unique among the sport's bigger tracks.

Dover hosted the first Cup race held after the Sept. 11 terrorist attacks on the United States in 2001. Dale Earnhardt Jr. got the win that day and took a giant American flag on a victory lap.
