Here's a Taste of Musk's 'Disturbingly Long' Underground Tunnel

Elon Musk's two-mile tunnel underneath Los Angeles is set to open to the public Dec. 10, and on Saturday, Musk offered a preview of what it will be like to travel the tunnel, tweeting a sped-up 34-second-long video. "Walked full length of Boring Co tunnel under LA tonight. Disturbingly long. On track for opening party Dec 10. Will be very one-dimensional," he added. The tunnel is a test version of what Musk ultimately plans to be networks of tunnels underneath congested cities around the US in order to alleviate traffic.

The so-called hyperloop tunnel, built by Musk's Boring Company, is ultimately planned to carry people, bicycles, and cars up to 150mph, per NBC News and USA Today. As TechCrunch explains, electric-powered "skates" will either carry cars that are driven onto them or will hold vehicles that can carry up to 16 passengers. The test tunnel is located near the SpaceX campus in Hawthorne; the day after the launch party, Musk plans to offer free rides to the public. (Musk has similar plans underway in Chicago and DC.)
