Circuit history:

Michigan International Speedway nestles on more than 1,200 acres of land in the Irish Hills of southeastern Michigan. Groundbreaking took place on September 28, 1967 and more than 2.5 million yards of earth were moved to form the D-shaped oval.

Designed by Charles Moneypenny (who had already designed the 2.5-mile Daytona International Speedway), the original layout included infield and exterior roads, which could be configured into a 3-mile or two 1.9-mile road courses.

The road courses were designed by Formula One great Stirling Moss and are still used on a limited basis for passenger car testing by area law enforcement agencies.

The last interior road course race was held in 1984, and the last time the exterior road course was used was in 1973.
