Hi.  I don't mean to take alway from this great thread. But, but I'm writing about the photo of the bridge Track Fiddler ("TF") posted.

I like this bridge.  I think his experience might help others - like me.  TF, would you mind telling us about your girders - purchased ready made or scratch built; how you attached the girders; and are they straight or curved?  If curved, how did you curve them?

Thanks and sorry for any inconvenience this communication may cause.
