Well, I've got the bridge to a point where it could be used at a pinch.
That's not the intended configuration but I don't have time to build approach ramps for the thing. The pieces I'm using as ramps would serve to extend the span considerably but this width is just nice for our version of the Maas.
I haven't done a proper paint job either. Apart from the grassy embankments these parts have just had a black undercoat and a quick splash of the relevant colours. I'll do some detail work over the next couple of evenings.
