I think this is a great effort but I wonder if they could have done something cheaper that can be put in many places. I am not sure how useful one super shiny crossing will be.
Half the ~$100M probably disappears in administrative BS.
Now that they've captured the federal government (re. Trump/Elon bromance), maybe The Boring Company can obtain some national environmental restoration funding and dig a bunch of holes to put the ugly freeways in.
If digging a short tunnel is a repeatable operation free of BS and possible at ~2-3x this cost (~$250M) then it could perhaps be widely replicated to good effect on relatively natural lands adjacent to but outside of core urban areas.
