I’ll tell you right now, you are insane if you think you are going to spam that long with a “connector plate” of some sort to join them. You shouldnt spam that far even if it was a solid beam. Asking for a disaster to happen.

You need multiple concrete spread footings on each side of the water with a vertical beam or concrete pedestal to support each beam. Either that or piles driven a good ways down.

Well, that's why I asked. Because I didn't know.
