Musk really had to dig tunnels to expose tunneling machines

[Global Science and Technology Report] SpaceX and Tesla's founder, billionaire Elon Musk, pushed his underground tunnel in December last year to solve the problem of traffic congestion in the United States, and pushed it on February 4th. Photographs of tunnelling machines (TBM) were released.

According to the British "Daily Mail" reported on February 6, Musk said "crowded traffic is mad," ready to dig underground tunnels to solve the problem, the tunnel has started construction at Los Angeles SpaceX headquarters. The completed test has a width of 9 meters, a length of 15 meters and a depth of 4.5 meters. Since the test trench is located within the scope of private property, it is legally excavated, but further extension of the tunnel requires application for a government permit.
