Reply to "Upper loop “base” material suggestions."

I suspended my upper level on 450 signal bridges using a plywood roadbed.  I used textured paint and lined the sides with girder.  Added oak stiffeners on longer spans.  Hid the wiring in “downspouts.  Signal wiring and controls hid nicely under the plywood between girders.
