Thanks Quincy.
"The Bible Camp transferred their ownership interest (if any)" ... is the key.
The question is, because they constructed the bridge on the private property of another, what ownership interest did they have?
I say none.
A court of law said differently when they granted the suit to quiet title. Therefore your opinion is meaningless. You could have intervened in the quiet title suit to try to stop the court from granting the suit but you did not do so. The owner of the land could have intervened in the quiet title suit to attempt to gain title to the bridge, but chose not to do so. No one challenged or appealed the court's ruling so it is a done deal.
However, again, it is possible for one person/entity to own land and another person/entity to own a structure upon that land.
On more time: You need to consult with a local attorney. You need to talk to someone who can explain things to you and you will believe their answers.
Please don't take this as being snarky, because it is not. You do not appear to understand some of the fundamentals of the law as far as these issues are concerned. You would not necessarily be expected to understand those fundamentals. However, when people are trying to explain some of them to you, you simply refuse to believe them which makes it difficult to help you learn those fundamentals.
