The tallest roller coaster in the world is currently held by Kingda Ka at the Six Flags Great Adventure in New Jersey.
In 2019 we were supposed to see a $250 million roller coaster located at the Skyplex complex in Orlando, Florida. The new ride would have towered 570 feet-tall and would have been faster than any roller coaster you’ve probably ever ridden.
Sadly, the roller coaster would have been called “The Skyscraper” and was slated to be completed this year.
However, according to Trip Savy, “For years, the projects’ owners kept adding new rides and features to the planned project while simultaneously pushing the projected opening date forward. The last date announced was a 2019 debut. Now, the Website that featured the project, known as Skyplex, has been removed (all but dashing hopes that it will ever get built).”
