Elon Musk’s Boring Company has unveiled its first completed tunnel in Los Angeles, US.
The 4.3km, 3.65m diameter test tunnel in Hawthorne, LA, has an entrance on private land and is bored between 9.4m to 21m below ground.
At the launch on Tuesday (18 December) Musk said that modified electric cars would be lowered into the tunnel and travel at speeds up to 240km/ph.
In a change to Musk’s original plans, the cars would be lowered into the tunnel by lifts and then slotted into tracks, instead of a system that could transport up to 16 people at a time in electric-powered pods or “skates”.

Last month, the TBM named Godot was lifted from the test tunnel after it broke through to the vertical shaft in Hawthorne.
The test tunnel has been used for Boring Company engineers as a “proof-of-process” tunnel, to develop construction techniques, and system and safety testing of the transportation.
