Massive New 300-Foot + Roller Coaster Coming Soon To Six Flags

Six Flags Over Texas in Arlington, Texas has some big plans in store for park visitors in 2026.

Late last year, the park confirmed plans for a new roller coaster, which it described as a 'dive coaster'. Six Flags said this new style of coaster would be 'record-breaking'.

To accommodate the new roller coaster, however, the park would have to remove two of its current rides. One of those rides is nearing completion of its demolition.

We're learning more details about the new roller coaster planned for Six Flags Over Texas

A filing with the Federal Aviation Administration (FAA) dated January 22nd indicates that an 'amusement park structure' is proposed for a site with GPS coordinates in the same location as the park's former bobsled-style coaster, 'La Vibora.'

The filing indicates the proposed structure is planned to be 309 feet high, making this new coaster the tallest among the park's 15 roller coasters. While there is no name for this new coaster, the project name on the filing is going by 'Project Rubi 1002' for now.

If this is indeed a filing about the new dive coaster at Six Flags Over Texas it will become the 9th tallest roller coaster in the US according to Rollercoaster Fandom. For reference, the tallest coaster in the US stood at 456 feet at Six Flags Great Adventure in New Jersey. The coaster was called Kingda Ka but was permanently closed in November of 2024.

What is a dive coaster?

Dive coasters were first introduced in 1988 and as of May 10, 2024, there are only 17 in the world. It's an exclusive type of coaster that is known for having one or more near-vertical drops where riders essentially feel the sensation of freefall. Examples of dive coasters can be found at:

• Valravn at Cedar Point in Sandusky, Ohio
