Modifications approved by the FIA and FIM were made to the former Formula One circuit. The new circuit now has 16 turns. The motorcycle course runs counter-clockwise, the same direction as the oval track. It bypass the banking of the oval with a new infield section inside Turn 1. Also, the double-hairpin at the Hulman Straight was replaced with traditional S-turns. The construction was finished before the opening day of the 2008 Indianapolis 500.
