The speed hill after the second drop, the double-up element, and several of the ride's other hills were reprofiled. In 1979, the ride closed for approximately ten months to remove excessive negative g-forces.

Modifications Ĭolossus underwent a number of changes over the years. It was the tallest and fastest roller coaster in the world, as well as the first to feature two drops over 100 feet (30 m). At a final cost of $7 million, Colossus opened to the public on June 29, 1978. During construction, a tornado caused part of the structure to collapse, but the roller coaster was still completed on schedule. The design was finalized in May 1977, and construction began a few months later in August. A member of the design team traveled to Mexico City to study Montaña Rusa – the largest wooden roller coaster in the world at the time – in order to help plan for the project. IAD in turn subcontracted Bernard Brothers Construction for the construction of the ride, Continental Consultants for all of the mechanical systems, and Lorenz & Williams for the structural engineering and electronic systems. They hired Ohio-based International Amusement Devices (IAD), who began designing Colossus in January 1977. It retained much of its wooden structure, however, and reemerged as Twisted Colossus on May 23, 2015.įor its next attraction to debut in 1978, Magic Mountain wanted a wooden roller coaster for the classic "rumble and sway" experience that they felt was missing from steel coasters. Rocky Mountain Construction renovated the ride converting its wooden track to steel, allowing for the addition of inversions and steep drops. For 19 years, it was the park's main attraction until the opening of Superman: The Escape.Īfter more than 36 years in operation, Six Flags closed Colossus on August 16, 2014. Colossus became well known after appearances in film and television, including the box-office hit National Lampoon's Vacation and the made-for-TV movie Kiss Meets the Phantom of the Park. It was the tallest and fastest wooden roller coaster in the world and the first with two drops greater than 100 feet (30 m). Originally designed and built by International Amusement Devices, the roller coaster opened as Colossus, a dual-tracked roller coaster, on June 29, 1978. Twisted Colossus is a steel roller coaster located at Six Flags Magic Mountain in Valencia, California.
