The Monster Mile of Dover International Speedway

The Dover International Speedway in Dover, Delaware, United States, is one of three publicly held concrete racetracks used in NASCAR races. The high-banked, one-mile long, oval racetrack with narrow straightaways is said to be one of the most challenging tracks in the competition. The turns at Dover International Speedway are banked at 24 degrees, which is among the steepest in NASCAR. But unlike most other tracks, the straightaways are banked too, at 9 degrees.
