The Boring Company has almost completed construction of a test tunnel under Los Angeles, which Elon Musk says will be open to public test rides in the coming months.

While Musk continues to deal with bottlenecks that are slowing production of the entry-level Tesla Model 3, he is still finding time to pursue his goal of fixing traffic congestion under LA.

Taking to Instagram, the outspoken entrepreneur and CEO posted a video from inside The Boring Company’s LA test tunnel. It apparently spans roughly two miles. and while it doesn’t appear anywhere near that long to our eyes, it does serve as proof of just how seriously Musk is taking this business.

You’ll still have to wait a while before it becomes operational

Before any member of the public can go for a ride through the tunnel, presumably on one of the company’s proposed sleds, The Boring Company will need regulatory approval. If everything pans out, Musk says the commercial version will offer rides to passengers for less than they’d pay for a bus ticket.

When The Boring Company was first established, Musk envisioned a system of interconnected tunnels where passenger cars would ride on high-speed sleds to avoid traffic. However, the company has since changed its focus and will initially cater for mass transit needs with public buses that ride on the sleds.
