Viper (Six Flags Great America)

Viper (Six Flags Great America)

Viper is a wooden roller coaster located at Six Flags Great America in Gurnee, Illinois, which opened in 1995. Viper features a layout that is a mirror image of the Coney Island Cyclone and is the only roller coaster ever to be built directly by Six Flags. Viper is also the only wooden roller coaster that has ever carried this name, (all the other Viper roller coasters, both operating and not, have been steel roller coasters). It was built by Rygiel Construction.
