The Boring Company CEO recently tweeted a video of the elevator that will lower the cars into the Tunnels, which will start operating next week.

The clip shows a vehicle riding onto a car skate, which then lowers itself underground into a network of tunnels.

At the time, Musk said At TED2017 in Vancouver his team was trying to “dig a hole under L.A.” to "create the beginning of what will be a 3D network of tunnels to alleviate congestion.”

Musk had previously told Bloomberg he planned to create a large underground network that would include 30 levels of tunnels for cars and high-speed trains, like the Hyperloop.

Am going to build a tunnel boring machine and just start digging.” In January, he held a Hyperloop competition outside SpaceX’ headquarters after introducing the concept of a few years before.
