Over behind the 1st launch structure you can spot here a small covered set of stairs and walkway. And near the bottom you can see that they've painted some supports with a rust texture ala Nemesis.
On the topic of the covered stairs and walkway though.
PHLMarcus of PhantaFriends recently shared his speculation about new paths, stairs and bridges that have arisen in the area.
Red: existing elevated paths, orange: existing stairways
Its
of course difficult to say which of these is perhaps only for evacuation or access purposes. However since these paths are covered and have built in grids so nothing can be thrown down, one would assume they are accessible by normal guests. A speculative suggestion for how it could be connected up as a queue line for F.L.Y. (with some extra annotations)
Would certainly be a great dynamic queue and add another dimension to Rookburgh winding its way through the area and coaster above the paths below if it does turn out like that.
