SpaceX, Tesla and Boring Co. founder and CEO Elon Musk took to Twitter Sunday to announce the Boring Co.'s first tunnel, which runs beneath Hawthorne, will be ready to open on Dec. 10.
The project promises to carry cars underground at speeds of up to 155 miles per hour.
An opening event is planned for Dec. 10, with free rides planned for the public the following day, Musk tweeted.
The tunnel runs about 2 miles under the streets of Hawthorne, where Musk's SpaceX headquarters is located.
Musk has described a system in which vehicles or people pods are moved on electrically powered platforms called skates at speeds up to 155 mph.
Musk wants to build a tunnel across western Los Angeles and another between a Metro subway line and Dodger Stadium.
