Built in 1999 between two gravel traps and next to I-605, Irwindale Speedway is a 1/2 mile paved
oval which also contains a 1/3 mile paved oval. A 1/8 mile dragstrip was added in 2001, and a
1/3 mile figure 8 in 1999. The 1/2 mile oval features compound banking, with 6 degrees of banking on the inside line, 9 degrees of banking about 20 feet outside of the inside line, and 12 degrees near the wall.
