What I might suggest about the bridge Yuri, is that it may have had a wood upper structure on stone piers. Infact similar to the one at the fort of Cilurnum or modern day Chesters in the Hadrianic period of course. I think with regard to the fort it would be well to read the account in THE ROMAN WALL by J Collingwood Bruce, for here there is a good desciption of the ground layout from the 1929 excavations.
