Elon Musk hopes to have a tunnel running under a 17-mile stretch of highway in Los Angeles "in a year or so."
"To solve the problem of soul-destroying traffic, roads must go 3-D, which means either flying cars or tunnels. Unlike flying cars, tunnels are weatherproof, out of sight and won't fall on your head," The Boring Co. website says.
So far, The Boring Co. has built 500 feet worth of tunnel.
In three or four months, the tunnel will be two miles long, Musk says in a tweet.
And "hopefully stretch the whole 405 N-S corridor from LAX to the 101 in a year or so," the iconic entrepreneur says, referring to two of California's famously busy highways and the airport.

According to Google Maps, that's a 17-mile journey that would currently take nearly an hour with LA traffic. (This estimate was generated Thursday at 11:15 a.m. EST, or 8:15 a.m. PST.)
That's just too much time for Musk. By comparison, traveling at 125 mph with zero traffic, that distance would take just over eight minutes.
In addition to tunneling his way under Los Angeles, Musk is the CEO of electric vehicle company Tesla and aerospace manufacturer and space services company SpaceX, and he is a co-founder of Neuralink, a company aiming to merge the brain with computers.
In December, Musk tweeted his frustration with the traffic in his hometown. "Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging."
And, well, he did, and is.
