I-70 Speedway is now the home to a state of the art facility and 1/2 mile dirt oval racetrack hosting events for every kind of motorsports enthusiast.

Roberts' third son Dan, a Kansas City area country music DJ on KFKF-FM and later a long-time announcer at Arrowhead Stadium, got his start in sports broadcasting at I-70 Speedway.

I-70 Speedway was also one of the first tracks to feature a prototypical SAFER barrier; during a World Cup race in the early 1990s, huge styrofoam blocks were placed high along the retaining wall in all four turns.

All-Pro Series driver and former NASCAR Rookie of the Year, Jody Ridley, hit one of the blocks which sent him airborne over the wall in turn four upside down.

Other notable drivers who had driven there (not all of them on a full-time basis) included Mark Martin, Butch Miller, Bob Senneker, Dick Trickle, Mike Eddy, Johnny Benson Jr., Jamie McMurray, John O'Neal Jr., track champion Terry Bivins,[1] Jenny White, and Jennifer Jo Cobb.

On July 5, 2018, it was announced that I-70 Speedway was bought by Chris Payne, owner of Heartland Motorsports Park and would reopen in 2019.

In 2023, Chris Payne and his partner entered into an agreement with Scott Higgs to invest in the development of a drag strip on the property next to the 1/2 mile dirt oval track.

World of Outlaws announced in December 2019 that they would return to I-70 in 2020, on a new 0.375 mi (0.604 km) oval layout, surfaced with dirt.

The effort was delayed a year by the COVID-19 pandemic, but a grand opening of the track featuring World of Outlaws occurred on April 30, 2021.
