There are so many concerns besides load carrying capacity when designing a pedestrian bridge. If the structure goes over a highway, you have to wrap the pedestrians in a cocoon of wire mesh to protect the drivers below. I think these fences are aesthetically displeasing and they seldom work well with the structure.
This tied arch over the Pan American Highway includes a tunnel of fencing, which does a good job of protecting drivers but it stick out unpleasantly past the arch. I suppose it's possible to make the fencing work with the arch, but I've never seen a satisfactory solution.
