I was just joking about the artsy diagonals. In going through this whole thread now - it seems they installed the flat slabs (walkway and roof) and were going to attach the suspension diagonals later. You can see in the photos the grid of bolts on the roof - all nice and neat - ready to attach the diagonals to. Perhaps if they had some temporary footings underneath mid-span that may have worked - but it seems pretty obvious to me that you don’t add the necessary supports until later.
I’ve seen photos of how they build suspension bridges - it is pretty amazing. The suspension cables following behind the pavement as it is built, with the roadway hanging out in mid air.

Riding across the Mackinac Bridge with my parents as a little guy, it just seemed incredibly supercalifragilistically amazing !
