Star Wars Land seems far overdue, but now that it’s underway it looks like it’s going to bring a lot of changes to Disneyland.

During construction, popular Disneyland attractions will be closed. However, the end result means that Rivers of America will be rerouted.

Disneyland Today confirmed this on Twitter:

According to a report on MiceChat, if the rumors are correct, the northwest perimeter of Disneyland will undergo huge modifications.

Disneyland’s Rivers of America and the Disneyland Railroad will need to be heavily modified and rerouted to make it all happen. The track of the Disneyland Railroad will be realigned for the first time since 1965. … The new railroad route will make a sharper right turn past Splash Mountain and head out towards what is now Tom Sawyer Island and the Big Thunder Ranch area. The tracks will pass along the backside of Big Thunder Mountain Railroad before making another dogleg turn to the north and joining the current alignment near the existing Toontown station. The Fantasyland Theatre will head off to Yesterland as the new railroad alignment is sent through that area, carving out some new acreage for a future Fantasyland expansion that is gaining steam with TDA planners now.
