Twisted Colossus

Colossus opened in 1978 as one of the largest dual-track racing wooden coasters ever built, with two nearly-identical trains launching from side-by-side stations and dueling down the hillside together. It became a fixture of the park for more than three decades, appearing in films and remaining a crowd favorite even as newer, more intense coasters opened around it.

By the 2010s the wooden structure had aged past the point of cost-effective maintenance, and the park closed it after the 2014 season to hand the footprint to Rocky Mountain Construction. Rather than tear the whole thing down, RMC kept large sections of the original timber bents and rebuilt the track in its steel I-Box profile — creating a hybrid that races on the same general path as the old wooden Colossus but rides nothing like it.

The result, Twisted Colossus, opened in 2015 with an s-shaped double-down where the two trains interleave through overlapping drops, plus a nearly vertical stall element that lets riders on both trains briefly stare directly at each other. At nearly a mile long, it's one of the longest hybrid coasters ever built, and the visible wood structure beneath the steel track is a constant reminder of the ride it replaced.
