The Disney Skyway was removed in November 1994 because it was too costly to make safety upgrades and prevent an incident. At Disneyland, the Fantasyland Skyway station remains, but the Tomorrowland station has been mostly removed. In 1998, Tokyo Disneyland closed their Skyway attraction and the Fantasyland station was removed to make room for Pooh's Hunny Hunt, while the Tomorrowland station was remodeled into a candy store.
Soon after, Disney began plans to build a smaller version of Space Mountain at Disneyland, and opened Disneyland's Space Mountain in 1977. The design of Disneyland's Space Mountain was replicated at Tokyo Disneyland in 1983 and Hong Kong Disneyland in 2005; the Tokyo version was significantly changed in 2006.
