Elon Musk, the CEO of the Boring Company, tweeted Friday that he hopes that the firm’s hyperloop tunnel in Las Vegas will be fully operational in 2020. 

"Boring Co is completing its first commercial tunnel in Vegas, going from Convention Center to Strip, then will work on other projects," Musk said. When asked by a Twitter user how long it will take to complete, Musk responded that the tunnel will be “hopefully fully operational in 2020.” 

The Las Vegas tunnel allows people to travel on Tesla vehicles underneath the Las Vegas cityscape at high speeds. Preliminary construction on the $48.7 million project began in September. 

The Boring Company also has a one-mile-long test tunnel in Hawthorne, California. Musk also wants to build an underground shuttle between downtown Chicago and Chicago O’Hare International Airport. The shuttle would allow passengers to cross 18 miles in 12 minutes. Musk has also proposed a high-speed loop between Washington and Baltimore. 

The Boring Company was founded by Musk in 2016 after he expressed his frustration with Los Angeles’ heavy traffic. The company said that its goal is to “solve the problem of soul-crushing traffic” by building the underground high-speed tunnels.  

Musk is also the CEO of luxury electric vehicle company Tesla and space exploration enterprise SpaceX.
