This bridge was a suspension bridge and was carrying the weight of the coal as well as the conveyor belt. I don't agree that the conveyor should be on layer 2 because the structure is exactly analogous to a highway bridge. The conveyor belt is equivalent to the roadway or pavement and is therefore IMO part of layer 1. Unfortunately, I did not save my photo of it.
