The Springfield ARCA 100 (formerly the Allen Crowe 100, Atlas 100 and the Dutch Boy 100) is an ARCA Menards Series stock car race held annually on the Illinois State Fairgrounds Racetrack during the Illinois State Fair.
As USAC was downsizing its stock car division, the 1983 and 1984 running of the Allen Crowe Memorial was co-sanctioned with ARCA.
The race reverted to the "Allen Crowe Memorial 100" (or a variation of) moniker in 2002 and kept it until being renamed the "SuperChevyStores.com 100" for 2014.
Roper's car slowed on the frontstretch, then hit the inside retaining wall.
He was unconscious when medical help arrived and later pronounced dead at Springfield Memorial Hospital.
Race start delayed to 1448 local time, and distance changed to one lap after 1559.
