nothing wrong with this design itself but some details of his example are problematic. 6km down from the midway point between LA and SanFran is loaded with faults and I'm no geology expert either but this close to the ring of fire I bet rock in that vicinity would be pretty toasty. Sure, maybe not exactly magma but could easy be like 160F.

There'd still be some major engineering involved; ATW the deepest transit tunnel at present, the Seikan Tunnel in Japan, is only about 140 meters below the seabed and 240 meters below sea level. On the other hand, there's a mine in South Africa that's nearly 4km deep, and people work down there for extended periods of time. The mine has several hundred km of tunnels, too.
