Pond Boss Forums GENERAL QUESTIONS Property Projects & Construction Building a small bridge in flood plain?

Yea no place around to cross, further down stream two creeks merge and this is why it backs up and floods some times. I was thinking of building the bridge then putting 55 gallon barrels under it and put two steel cables and tie off to a tree, so this way when it floods the bridge will be on top of the water and anchored to two trees, but not sure if this would work or not.
