Monaco Gateway Classic

The Monaco Gateway Classic was a NASCAR K&N Pro Series East and NASCAR K&N Pro Series West race at World Wide Technology Raceway at Gateway held from 2018 to 2019, The 1.25 mi oval is a favorite of many of the drivers who race there due to the unique shape and different degrees of banking in each corner. Turns 1 & 2 have characteristics similar to New Hampshire Motor Speedway while Turns 3 & 4 are similar to Phoenix International Raceway and the track's egg shape mimics the legendary Darlington Raceway. Several NASCAR Sprint Cup Series teams test at Gateway in preparation for these events.

There is also a 1.6 mi infield road course used by sports car clubs and motorcycle organizations through the warmer months. This road course hosted a round of the AMA Superbike Championship in 1995. Canadian Miguel Duhamel won the superbike class in blistering hot conditions.

In early-January 2008, it was announced that the Missouri-Illinois Dodge Dealers would move their sponsorship from the NASCAR Craftsman Truck race to the NASCAR Nationwide Series race, and was called the Missouri-Illinois Dodge Dealers 250. At the 2008 event, Carl Edwards became the fourth driver to win two NASCAR Nationwide Series events at Gateway.

2008 was a big year for the NHRA at Gateway, as legendary 14-time Funny Car champion John Force earned his 1,000th career win overtaking Ron Capps. Making the event doubly special was that it take place on his 59th birthday only one week after losing to his daughter Ashley Force in the finals at Atlanta for her first career win in the Funny Car series. Another was that Rod Fuller beat his arch rival Tony Schumacher in the finals, which became a big win for him as it represented one of the very few times Schumacher would be beat in an historic season for The Sarge, who won 15 races with seven of them consecutively with 31 round wins in a row, en route to his fifth consecutive Top Fuel title and his sixth overall.

The NASCAR Camping World Truck Series race at Gateway was sponsored by Camping World, becoming the Camping World 200. Coincidentally, the race was won by defending Truck Series champion Ron Hornaday Jr. driving the No. 33 Camping World-sponsored truck for Kevin Harvick Inc..

In 2010, Gateway received a second Nationwide Series race due to the closure of Memphis Motorsports Park. The date was the former late fall event at Memphis. This was the last NASCAR event held at Gateway until 2014, as Dover Motorsports announced it will not seek sanctioning for the three events held there in 2010. The track did not make an announcement concerning any of the other events the track holds. The former Nashville Superspeedway got Gateway's place on the schedule in July, while the race date for October would still be vacant. The NHRA did not schedule any races at Gateway for 2011 either.

On November 3, 2010, Dover Motorsports announced that Gateway was officially closing and ceasing all racing operations there. On September 8, 2011, it was officially announced that Gateway would re-open in 2012 and host the 15th AAA Insurance NHRA Midwest Nationals from September 28–30, under the leadership of Curtis Francois. On December 6, 2012, USAC announced that the track would have a USAC Traxxas Silver Crown Series date in 2013 on June 1.
