I can see it now. 30 years the thing will be ready for opening after spending $150 billion to link SF and LA and the day before it opens a big earthquake hits, knocking at 50% of the bridges.
The greatest waste of money in world history.
IF it ever gets built.
Its safe to say though, none of us alive on this thread will get to ride it should it happen by some miracle.
Just bottomless spending up the wazoo and nothing gets done.
That will still be finished before a 2nd-level US Highway extension first discussed here in the late 1950s
