I don't know what interstates they travel on, but the ones that I travel on have a lot of bridges that don't exceed 14-some feet of clearance. It must end up being a pretty convoluted route.

You are entirely correct, routing this kind of truly outsized cargo is a major effort and the Interstates are not useful generally, because they were designed with insufficient bridge clearance.
Often the convoy creeps through the countryside at very low speeds in the wee small hours, over some weeks. So leasing an An 124 is massively more efficient.
I think the airship delusion gets reinvigorated every time one of these big lumps must get moved from A to B.
