Which bridges are still convenient for train photography between Reading and Didcot ?

[Picasso]

Hello,

Having planned half a day along the GWML between Reading and Didcot on 17 August, I would like to kwow which bridges are still suitable for train photography, and which are not (under reconstruction, rebuilt with high sides...).
I intended to go to one of Purley-on-Thames bridges, or at Cholsey.

Thank you for your help.

I think there is a road bringe at the east end of Goring and Streatley which might be suitable; it runs at about a 30° angle to the line as well meaning the south side approach road might be good as well, if not better. Not sure of the fence height though.
