It's possible the bridge would be less stressed with the backhoe on the trailer rather than driving the backhoe across solo.

That could easily double or triple the load on the bridge per bounce. Also is the bounce of the tractor is "in rhythm" /same frequency or a harmonic. The backhoe could shake/bend the bridge to bits as it sways/bounces with higher amplitude. Anyone who has stood on an elevated wooden floor like a hayloft or wooden foot bridge. They have suddenly felt the floor/bridge shake, feeling it was starting to give way underneath them. The cause turned to be just the dog trotting along the same structure.
