If the layout we have at our disposal is to be believed, then what you're saying is this coaster is going to make two passes OVER the bridge in near impossibly close proximity? I'm struggling to see a situation where that'd be the case.
There's certainly room for a banked turn through one of the middle sections, but at this point it'd be a little hard to install the track with a complete bridge. Unless this is another temporary(but more rugged) bridge to help with the summer/Hagrid crowds and some of the construction, and then they're gonna do a permanent bridge during the slow season.
Either that or the layout in that area has changed.
@Alicia, heard anything new?
