QuoteTRON Lightcycle Power Run will open at the Magic Kingdom just before the park's 50th birthday (probably 2020/21), replacing the Tomorrowland Speedway attraction which opened in 1971 as the Grand Prix Raceway. The Speedway will likely close sometime in 2018 to make way for this construction.http://wdwnt.com/blog/2017/07/confirmed-tron-lightcycle-power-run-rollercoaster-replace-tomorrowland-speedway-magic-kingdom/
