Concrete, like the one slab already running across the track before the spike that's there now, covering entire spike. And then rockwork facade around the structure to disguise it.
Also, more rockwork in the middle of the area, where that row of port-a-potties is now, to hide Fluffy from view.
EDIT: Pretty much every structure that's coming is already in place, or in the process of being themed, except for these. Pretty much.
