LO#1 - Bridges on the club railroad

On the far end of the 5'x10' club layout there is a curved upper track passing over a curved lower track at a quite close angle.  The upper bridge will be 21" on the outside and 18" on the inside.  I am looking at building a three segment through truss bridge with three 7" segments on the outside and three 6" segments on the inside.  They will have to be supported by extended beams to supports beyond the lower track.  Both curves are 23" radius, the layout minimum.  We meet Saturday morning so will try to get some pictures and maybe some mockups.  I know it is not very prototypical but was done in cities on the ells.
