The closing day caused such a stir online that one might have thought the area was being permanently removed, but thankfully the next day Disneyland shared new concept art of the area to help fans pass the time.
The park's railroad will cross a massive trestle, set among tall roaring waterfalls and intricate rockwork. Many of the area's famous displays will be relocated, like the Indian village, which of course means some will not. This new North part of the river will be backed by mature trees, creating a berm separating it from the new Star Wars land. Disneyland isn't totally confirming that all current forms of water transportation will return, though several of them can be seen in this new art.
For now the bulldozers will roll in and heavy work will soon start - but we can count of plenty of updates as time goes by!
