This barge, holding this monster crane, appears to be lowering one of the supports for the new Forth Replacement Crossing into the river.
What do I mean by "monster"? Well, it’s taller than the Forth Road Bridge’s platform. I took a pic from the other side of the river and I’ll upload that just to show how huge it was,
The thing was so high that traffic across the Forth Bridge slowed markedly, as people tried to get a look at the thing! It was massive!
