Nice idea - a pre-cast and/or poured concrete bridge - makes a change from the twee rose tinted chocolate box traditional brick/stone bridges
Can't help thinking if the concrete was poured on site wouldn't the wing walls be stepped or at a much shallower angle than 45 deg to prevent the concrete slumping? Unless they are pre-cast concrete slabs poured off-site.
Concrete bridges can be a fascinating subject in it's own right.
I quite agree - there's something nicely brutal about them. I was basing the angles on the structures on the Fawley branch which I've seen quite a bit of cycling around that area and they seem in line - the pour follows the shuttering of course . You can see this here: Google Maps and here: Google Maps (New Road, Hythe).
This bridge at Ketton is slightly different (it's all concrete for a start) but again, the angles aren't so different: Ketton Fowler
