An actual flat bed trailer would work well too. But a box trailer, if you cut the sides and top out, would be the same as I mentioned earlier about the storage container.
We bought a used flat bed semi trailer. 45' X 8'. Guy we bought it from delivered it and kept the axles. Pulled it across with a winch on our D4. All steel and aluminum as on the highway caarries 40k. Added a hand rail and were done.
I built a bridge on my farm last summer using telephone poles running across with a wooden deck on top. So far the bridge has done great. I use it to access a big portion of my property that is cut off by a creek. I drive my truck and tractors over it quite often and it does great. The best part is the little money that it cost to build.
