2021 will be Walt Disney World's 50th anniversary, and a certain ride will be finished and available by then. The TRON Lightcycle Power Run Rollercoaster located in Tomorrowland seems to be currently under construction.
Some photos have been taken of the construction site from where it's, at the moment, visible in the park. Personally, when I look at the concept photo, I'm super excited for what the ride will look like in real life. The scale of this ride seems massive with multiple buildings, and the design looks so cool and futuristic.
I can't wait to see what DIsney has in store next!
