• Tesla and SpaceX CEO Elon Musk launched the Boring Company earlier this year.
• The Boring Company's aim is to build tunnels that could transport cars or support high-speed transit systems like the Hyperloop.
• The company is making progress on its test tunnel in Los Angeles.

Tesla CEO Elon Musk gave the public a glimpse of his tunnel under Los Angeles this weekend.

Musk posted a photo on Saturday showing the tunnel dug by the Boring Company, the serial entrepreneur's latest venture. Musk's ultimate goal for the city of LA is to build a network of tunnels that can transport cars and help alleviate traffic in the most-congested US city.

Musk said the tunnel is currently 500-feet long but should stretch two miles in four months. The tunnel is being dug in SpaceX's parking lot at the intersection of Crenshaw Boulevard and Rocket Road in Los Angeles. 

The Boring Company was granted approval in August by the city of Hawthorne, California, to dig the tunnel so it could prove its electric skate technology. The company wants to build an electric skate that can rocket cars through the tunnel, like so:

So far, the tunnel can only be used for research and development; once the Boring Company has finished testing the electric skate, the city of Hawthorne can request that the Boring Company refill its hole. The company is seeking approval to extend the tunnel under Interstate 405 of Los Angeles International Airport.

The Boring Company is also pursuing projects in Chicago and along the East Coast.

The company was granted state approval to dig a 10.3-mile tunnel beneath the Baltimore-Washington Parkway. It would be the first leg of a Hyperloop system that would extend from Baltimore to New York with stops in Washington and Philadelphia. 

A Hyperloop is a nascent transit system that experts say could transport people in pods at speeds exceeding 200 mph.
