Colorado is one of 35 worldwide semifinalists vying to build a hyperloop, proposing a 40-mile high-speed link between Denver International Airport and Greeley.

Los Angeles-based Hyperloop One received 2,600 proposals in five months to build the levitation-based technology that would carry passengers and cargo at speeds of up to 700 mph, according to the Colorado Department of Transportation. The finalists will be announced in May.

“We are excited about the opportunity to provide the progressive perspective that Hyperloop One brings — it will change our customers’ current perception of transportation and, as a result, revolutionize what we think we know,” CDOT executive director Shailen Bhatt said.

The Rocky Mountain Hyperloop team is up against semifinalists from 17 countries. The United States has 11 teams in the running.
