Just the other day, he Tweeted that an initial test segment of a tunnel was completed. Now, Musk has shared a video of the finished skeleton for the first car-transport elevator.

The elevator is just one of many that The Boring Company plans to build to transport vehicles to underground tunnels. This same type of boring and underground infrastructure system will become part of Musk's plans for his human civilizations on Mars.

In the original Boring Company teaser video, Musk shows electric cars, and multi-passenger transport "sleds" heading down to the tunnels. No one is certain if this concept will make it that far, but regardless, tunneling is underway, and the elevators are being constructed.

Musk previously Tweeted that The Boring Company is "no longer waiting for Godot". He affectionately and humorously named the first boring machine, Godot, after the Samuel Beckett stage play. Musk also added a Tweet with some video footage of where the tunnel leads.

Musk plans to build an entire network of tunnels underneath LA and other cities. The first digging began in Hawthorne, CA in the parking lot of the SpaceX headquarters.
