That 68 billion could end Kalifornia’s drought problems forever, by way of aqueducts from soggy Washington and Oregon. Fact. Pretty much follow the existing I-5 corridor.
Better yet, invest it in desalination plants to serve the big coastal cities. Oh, I forgot. They use "evil" electricity produced by either nukes or fossil fuels. I guess the RR/tunnel is an electorally safer endless boondoggle for the corrupt politician/union complex.
