Making a grid.

I am no bridge engineer but I have worked with such people in the past so I understand a bit about bridge structures. So, I do know that the bridge deck sits on cross members that then sit on the girders. I certainly would not trust a real bridge that I designed but in model form it does at least look something like a real bridge should! On that basis I cut the required cross members from some plastic card and these then formed a grid pattern over he girders which I had cut to the right length.

Putting the finished steel (or should that ne plastic?) work onto the underside of the bridge it begins to look like a real bridge should. It just needs painting once the glue hardens and then it can be glued into position.
