The pieces are starting to come together for the world's tallest water coaster.

The new ride is under construction at Schlitterbahn's Galveston park. The MASSIV (German for "massive") will be 926 feet long; that's more than twice as long as any other slide in the park, the Houston Chronicle reports.

Officials are keeping the height of the MASSIV under wraps for now. But they have said that before riders can take off, they'll have to make their way up 123 steps to board the slide.

Officials at the park, which is celebrating its 10th anniversary in Galveston this year, say the Massiv will be ready for summer visitors.

Two summers ago, Schlitterbahn opened the Verruckt slide at its Kansas City, Kan., park. The ride, which means "insane" in German, was certified then as the tallest water slide in the world by Guinness World Records.

The slide drops 168 feet and takes riders in a three-person raft on a 60 to 70 mph journey.
