Disney World fans are fuming after the theme park announced the closure of three of its most iconic attractions: Rivers of America, Tom Sawyer Island and the Liberty Square Riverboat. The beloved destinations are set to shutter on July 7 to make way for Piston Peak National Park— a new attraction based on the Disney and Pixar “Cars” universe.

Disney announced Tuesday that Piston Peak National Park will be the "largest expansion in the history of Magic Kingdom," continuing "the sweeping storytelling tradition that has crossed Liberty Square and Frontierland since opening day."

Walt Disney World's upcoming Cars land will be called Piston Peak National Park and will be part of the "largest expansion in the history of Magic Kingdom," Disney has announced.
