It has been billed as an opportunity to learn about Musk's "vision to alleviate soul-destroying traffic through Loop, a zero-emissions, high-speed, underground public transportation system!"
"If you build a tunnel in L.A., you can build one anywhere", Musk said, referring to the various challenges the test tunnel would need to overcome in the city, including seismic conditions, methane gas, oil fields, and regulations.
The test tunnel will stretch almost three miles along Sepulveda on LA's Westside, one of the most traffic-congested parts of the city.
The full-fledged project would include a tunnel along Los Angeles' notoriously busy 405 Freeway where, Musk said, traffic varied between the seventh and the eighth circles of hell.
There were concerns that the project of a high-speed transportation tunnel might interfere with the area's rail projects.

Elon Musk has also suggested building such hyperloop tunnels in other cities outside of Los Angeles like New York, Baltimore, Washington D.C., and Chicago.
Elon Musk touted a partnership between the Los Angeles County Metropolitan Transportation Agency (MTA) and The Boring Company, his tunnel-digging venture. The tunnel would run southward under Sepulveda Blvd. and would end, without surfacing, below the vicinity of the intersection of Sepulveda Blvd. and Washington Boulevard in Culver City. If the Boring Company wins all the regulatory go-aheads that are required, Musk's past record of hard-to-imagine achievements may be a big reason why.
That announcement on Thursday night preceded a public event Musk held in the LA suburb of Bel-Air on Thursday night, during which he and Boring Company officials talked about the tunneling activities and took questions from members of the community.
The West L.A. tunnel is the latest project Boring has undertaken after quietly digging a slightly shorter tunnel underneath tiny neighboring municipality of Hawthorne, where SpaceX and Boring are both headquartered.
The 150-metre (500ft) shaft, excavated by The Boring Company, "should be two miles [3.2km] long in three or four months", Musk said at the time.
"You won't hear us, you won't feel us, you won't even know we exist", Davis said.
