The bridges are all screwed and bolted together so that they can be taken apart in case we move when I retire or if I put them up for sale
I have the plans in a cad program and .dxf files and the main drawings in .dwg I could add all the dimensions to the drawings. It would take a little time but I will do it if someone wants a drawing. The difficult part is getting the use of a machine to cut the parts out.
