That discusses 'superloads', I hadn't heard it called that before but it's accurate in the sense that things like self-propelled modular transporters (or towed equivalents) can move just about anything just about anywhere IF the road infrastructure all along the route is amenable to it.

Pictures don't do them justice, they're amazing to see in person. I think a typical SMR is on the small end of what's possible to move by road.
