The roller coaster opened on March 31, 1973 as part of a new themed area called Cotton States Exposition of 1895.
From March to May 1993, in celebration of Great American Scream Machine's 20th anniversary, the trains were turned to run backwards. The coaster ran backwards again from March 10 to May 13, 2018.
In 2017, the Cotton States Exposition became Metropolis and the Lickskillet area was expanded to include Great American Scream Machine.
Great American Scream Machine features an out-and-back layout that travels over the water with eleven drops. The color scheme of the ride is a combination of the colors, red, white, and blue; the colors found on the flag of the United States of America.
