Hyperloop One, one of the companies looking to bring Elon Musk's idea of super-fast ground transportation to the public, says that 11 possibles routes inside the United States are in the running to receive support from the company.

Thirty-five total routes around the world are competing to be one of the three that will "work closely with Hyperloop One engineering and business development teams to explore project development and financing," the firm says.

What's next: The company will whittle down the options to the three finalists. Hyperloop One also announced on Thursday that it had just finished a test track in Nevada.
