Newcastle (Pons Aelius) Bridge, Vallum and Fort (info needed

[MARCVS PETRONIVS MAIVS]

]If, as shown, the fort connected to the wall, then now all we need is to sort out the bridge.

I think you may have misread the plan, Yuri.
No-one is quite sure where Hadrian's Wall lies in relation to the Newcastle fort, but it certainly seems that the fort was free-standing, some way behind the Wall.

Yes I did misread it, I've seen now how it looks. Thanks.

The general views have been that the Westgate road is the line of Hadrians' Wall, this is the only road in the City that is absoloutely straight and comes all the way down from the fort of Condercum to about 100yrds above the Castle Keep.Therefore I would also say the fort has to be standing back from the wall, however with a projected line from the north end of the swing bridge the roman road passed the fort on its east side.

Thanks Brian, that helps a lot.
