Silver Dollar City announced its biggest ride yet on National Roller Coaster Day.

The theme park will open Time Traveler next spring. SDC calls it the biggest attraction and investment ever, by far, at $26 million. The project is two years in the making.

It promises a something never seen before anywhere, custom designed for the mountainous terrain of the Ozarks! It will be the fastest, steepest and tallest spinning roller coaster in the world. You begin with a 10-story, 90-degree vertical drop, going from a standstill to 47 miles per hour in three seconds. That is one of two double launches. You will also go upside down while spinning. It has three inversions total. It also includes a 95-foot tall roll, and an acceleration from 30 mph to 45 mph in 3.5 seconds. The ride goes up to 50 miles per hour. Its tallest point is 100 feet.

The largest coaster club in America, American Coaster Enthusiasts, will hold its spring convention at Silver Dollar City for the opening of this new attraction.

While Silver Dollar City usually takes people back in time, park leaders say this investment is about the future of the Branson community.

"We believe in tourism of Branson. We believe that a project of this size, a project of this scope, is so significant that we will drive more visitors to Branson," Silver Dollar City President Brad Thomas said.
