Thanks guys.
Textured, scribed and attached the capping stones...
Also filled underneath those to make for easy casting, I'll cast this for the other half, tried to do it so it sits in the shadow and isn't immediately obvious...
One thing which bugs me about a lot of bridges in 6mil is how they're often too narrow to put a base of troops on, I'm aiming at fitting a 40mil base. Hence the length of the span. A short and wide bridge wouldn't look quite right, this will have correct proportions so be acceptable to the eye, well mine at least.
