The track was designed with influence from Rusty Wallace and patterned after Richmond International Raceway, a short track where Wallace was very successful. It has over 25,000 permanent seats as well as a unique multi-tiered Recreational Vehicle viewing area along the backstretch. It is one of only three tracks on the NASCAR circuit to have a SAFER barrier installed around the entire circumference of the outer wall (with Martinsville Speedway and Atlanta Motor Speedway being the other).
