Sorry for the slow response, I haven't check the boards in a few days.
Screamscape seems to have released the same artwork that I was leaked last month but asked not to share, sorry I had to be vague. Now that it's in the wild, I can confirm that the original plan (as presented to the govt) to build across Hollywood Way and use the existing IOA-side path was replaced with this garden bridge over adventure way and garden path along RPR.
BUT there is no way this new path will be done by 3/31, so there will have to be a way to cross Hollywood Way and walk along the current sidewalk at least temporarily. Shuttle busses alone can't handle the massive number of guests at CBBR.
