This is intended to be a re-creation of popular parks in large cities where elevated railways were turned into parks (and long walks) creating nice space without traffic. New York City and Paris both have great versions of this kind of renewal.
It's amusing to build a "new" one though.... but will be a welcome space to escape and relax above the crowds at "Confusing Springs*."
*That's for all the people who won't be able to tell Disney Springs apart from Saratoga Springs, and the bus drivers who are still trying to keep guests straight on Fort Wilderness vs. Wilderness Lodge.
