I think the rolled up (and uninflated) pontoons as shown in the photos should be fairly easy to make. The trucks would look a bit empty with just the Treadway sections used as a load.
You have to add also the elements of the saddle.
On the model the saddle is catsed on the pontoon but it is composed by 8 seprate plates and two beams, 1 ton in all.
In the first pic the saddle is already in place to speed up the erection of the bridge, so each pontoon weights about 1,5 ton. You will need a crane to load/unload them.
