Danny, I don't wish you any bad luck and you certainly are
determined to complete your project BUT it will be for naught.
Mother nature will get you again. You really need some consulting
engineers to finish the "project" before it goes down again.
If your trees never moved it would be a different story but
the variables are against you.

What? You're not our consulting engineers?
I have proof that we consulted you, and everyone here!

To your point, the trees did move in the last Pineapple Express
which caused the last slung section to crumple to the ground:

It also caused the wood to split in a couple of places:

We determined it was, as you said, because the small trees moved,
so, we detached the bridge from the small redwoods in the middle:

Now the bridge is no longer attached in the center, to the
small redwoods to either side of the 10-foot-wide section:

One other problem is that the bridge "bent" in the middle; but
we'll plan to resolve that when we do the final leveling:

We only have about 8 feet to go, and then we can walk from
ground level, to something like 30 or 40 feet up, over about
75 feet of length, and be flat and level the entire distance:
