QUOTE: Originally posted by nfmisso Depends on your era. In modern times, a ballasted concrete deck type, earlier, either of your lower pictures, with the bottom one turned upside down. A bridge/trestle for each track is more likely on a curve.

QUOTE: Originally posted by Robert Knapp The bridge to be built is skewed and needs to be quite wide. Top timbers do seem out of the question, the bridge would look out of proportion. If you don't mind building the skewed timber bridge, timbers can anchor into the abutments, it should work and look great. Did you consider spanning the gorge with a skewed stone arch? Foam, 1/4" ply and sheet stone castings. This would be a simple solution, subroadbed/ roadbed can be continued and run a ballasted deck. Save the wooden truss bridge for a different spot, preferably not on a curve. Bob K.
