A little more from the Robert Street Bridge. Most of the piers on the bridge, near the top, there is a decorative emblem of some sort or another. They are not all faces like this one shows, I guess I haven't really gotten close enough to take a good photo of the detail before. I do know some of the piers have emblems, as I barely captured one in a photo I took back in 2006 which can be seen here. What do all these symbols represent, my very brief search found nothing.
