The first pieces are in place in Galveston for the forthcoming world’s tallest water coaster.

Schlitterbahn Waterpark will celebrate a decade on the island with a new thrill ride called MASSIV (German for “massive”). The water coaster will be extensive: 926 feet long. That’s more than double the length of any other slide currently at the park.

The height of the alleged “tallest” water coaster has not yet been announced. Riders will need to carry a tube up 123 steps to board the slide.

Park officials released a video Friday showing the initial construction on MASSIV’s tower. Andrew Mulligan, install advisor for construction company White Water, said everything is on schedule for a summer opening.

He said the project’s design needed to factor in two key challenges: The weight from the water that flows up to the top of the tower and also Galveston’s location in a hurricane zone.

Said Mulligan: “They’ve put up water coasters before but nothing this high. So there as excited about it as I am.”
