Has anybody built a wooden trestle on an incline? I've got a 3% grade across the span for the bridge. I had two identical bents made when it dawned on me, the top of each bent needed to be at a different height. But this doesn't seem right. All bent tops should be in plane (level) and copies of each other, right? My original thought was to attach each bent cap to the stringers (as you would on a level trestle), but then I realized this would cause the girts, etc to be on an incline as well. That wouldn't look right, would it?
I could build a level trestle, then add small risers to each bent to build the grade, but would this be correct? How would the prototype do this?
Thanks in advance,
