So like, at the risk of sounding stupid; what are the curved cables at the top of these style bridges for? They don’t appear to be under any amount of tension, just drooping slightly above the surface.

I think the curve is about load distribution and material cost. I think the curve allows the load distribution to pull downwards on the supports rather than sideways. So strength would be improved.
