Drag track combined with speedway
Benton -
The nicest combined-purpose single location I'm aware of is Las Vegas Motor Speedway in Nevada. See the link below for an aerial photo of the complex:

The 1200-acre (490 ha) complex has a 1.5-mile superspeedway for NASCAR, a national event caliber dragstrip for NHRA, 2.5-mile roadcourse, 1/2-mile dirt oval, a 3/8-mile paved 'Bull Ring' oval, and kart tracks.
Locally here in Southern California, the complex in Fontana has a 2-mile superspeedway for NASCAR and IndyCar with a multi-configuration road course in the infield area, a NHRA-sanctioned dragstrip just outside the north side of the superspeedway, and a kart track.
Also in SoCal, Irwindale Speedway has both a banked 1/2-mile paved oval, a 1/3-mile paved oval, and a 1/8-mile dragstrip.
Pomona, where the NHRA Winternationals and World Finals drag races are held is also here in SoCal. That facility is a dragstrip only and only operates several times per year because of local noise ordinances.
