DOVER, DE:  Dover International Speedway is a NASCAR-sanctioned 1 mile (1.6 km) race track located in Dover, Delaware, owned by, and serving as the corporate headquarters of, Dover Motorsports, Inc. It is co-located with a harness racing track, Dover Downs, and shares the complex with Dover Downs Hotel & Casino. At one time both the entertainment complex and the speedway were owned by the publicly traded Dover Downs Entertainment, but they have since been split into two separate companies.

Dover is unique in many ways. It is exactly one mile long; technically this means that it is neither a superspeedway nor a short track. The speedway surface is concrete; most NASCAR track surfaces are asphalt (Dover was at one time an asphalt track, however; it wasn't until the mid-1990s that the asphalt surface was replaced with concrete). Dover is one of three concrete ovals used in NASCAR's three major series; Bristol Motor Speedway and Dover's sister track Nashville Superspeedway are the others (Dover and Bristol are the only two of the concrete tracks used by the Sprint Cup Series as Nashville has yet to receive a premier series date since its 2001 opening, despite hosting Nationwide, Truck, and IndyCar races).
