As rumors swirl about the future of Kingda Ka, the fates of three other rides at Six Flags Great Adventure have become clear. Green Lantern, Twister Top, and the parachute ride are all slated for demolition, according to construction permits filed in Jackson Township, New Jersey, this week.

Six Flags is investing $1 billion for park improvements over the next two years. A new roller coaster is to replace two rides in the Arlington park.

The record-breaking ride, Kingda Ka, is officially being retired nearly two decades after it first opened in 2005
