The new ride has had steel tracks added to the 1978 wooden structure, Colossus, according to the Los Angeles Times. The structure features dueling coasters with slight differences in route. The first part of the coaster is done on the blue track, and the second part is on the green portion, according to the Times report.
The most unusual feature about the new ride is a "high-five element" that, when done properly, places both trains side-by-side at 90-degree angles allowing for a potential high-five; the execution of the actual high-five is reportedly undoable, but it's one-of-a-kind nonetheless.
Idaho's Rocky Mountain Construction developed Twisted Colossus and similar upgrades to wooden coasters at Six Flags throughout the nation are expected in the coming years.
