Caergwrle Bridge Apparition Ghost Picture

Dave sent in this ghost picture of an apparition.  It is a photo of the Caergwrle Bridge in North Wales, Great Britain.  The apparition and the entire photograph appear to have the same "graininess" and seem unaltered.  Is it an apparition?  You decide...

Astounding shape and form of a robed figure.  Though not clear, is it a capture of an apparition on the bridge?
