Shortly after the oval track was constructed, the inaugural Motorola 300 was held on Saturday May 24, 1997 as part of the CART series. It was scheduled for the day before the Indianapolis 500 of the rival Indy Racing League. Rather than scheduling a race directly opposite the Indy 500 (as they had done in 1996 with the U.S. 500), CART scheduled Gateway the day before to serve as their Memorial Day weekend open-wheel alternative without direct conflict. On one instance, a couple of drivers actually competed in both events in the same weekend. The race was held on Memorial Day weekend for three seasons.
