This is a N Scale 104 ft. plate girder bridge. The following are some abutment options. I knew what I needed for abutments so I printed the center and wings as one piece. Since I don't know what you need I broke the center and wings into separate pieces. If you need a wing on the other side mirror it in your slicer program if possible. . Here are a few pictures of the initial install on the layout. . Later I'll paint the bridge and abutments and then glue them together and put them in place as a unit. . . More info on how the bridge was installed on the layout ( HERE ). Print files for the bridge and abutments ( HERE). You can find all the files to 3D print this object and others on my thingiverse.com account ( HERE ). Sumner
