I do not know about a bridge but if you look closely as he scrolls over the site where "stream obstruction 100%" comes up there is a empty stream bed that flows to the tree. Then if you look around the tree there is sort of the same thing that then flows around each side to a little pool which then falls into another pool that connects to that empty river bed that leads out on the left hand side. There may come for a need to build a bridge after that stream is flowing. Also when he scrolled over the "main hut" it asked for "3 more herbs". Right next to the pot is a grill and what may be a sifting box( heres hoping). I'm hoping that the main hut can have a roof built over it or everyones gonna be getting a little wet. As for the poles on the cliff, I have not a clue.
