I have planned a 40" long 0-42 curved overpass over an 0-54 curve. The longest unsupported span is 12". The width of the overpass ranges from 4 to 6". The layout is luan 3/16" plywood screwed/glued onto 1" styrofoam to steel studs. The thickness of the overpass is critical in that it increases the grade. I plan a 5 7/8" vertical clearance. Home Depot has rather rigid clear 3/8" ash, a wood that I have not worked with. any suggestions?
