Nope, the ring of steel goes over the roofs via the arches and the north/south stands.
I was lucky enough to go on a stadium tour in a group, along with Martin Perry and Richard Hebbard around a year / 18 months before they finished the thing. They went into great detail on the structure design as we walked around what was then the shell of the stadium. They even gave us a little nose-tap as to the large flat exposed concourse-sized area in the East stand, where a few years later the 2nd tier would be built (but had not been officially 'declared' as we only had permission for 22,500 at that point). Fascinating tour.
I'm an absolute stadium NERD so this was utter nectar.
I was just going by a diagram I saw, perhaps it wasn’t labelled clear enough. Can’t remember where I saw it.
You might’ve guessed from my little model that I am also a bit of a stadium nerd
