The Dark Knight Coaster is the name of three enclosed steel roller coasters located at Six Flags Great Adventure, Six Flags Great America, and Six Flags México. They opened in 2008 and 2009, timed closely to the theatrical release of The Dark Knight. All three installations were manufactured by Mack Rides. History Six Flags Great Adventure At Six Flags Great Adventure in Jackson Township, New Jersey, Batman & Robin: The Chiller and Movietown Water Effect were removed to make way for the construction of The Dark Knight. The roller coaster primarily occupies the previous location of the Movietown Water Effect, with the queue area placed in front of the building. Original plans called for the demolition of the Batman & Robin: The Chiller station and observatory but were later excluded from demolition plans. The exit was originally slated to go through the present Justice League gift shop adjacent to the ride, but this turned out not to be the case. On May 15, 2008, The Dark Knight officially opened to the public. Six Flags Great America At Six Flags Great America in Gurnee, Illinois, the building housing Theater Royale was extensively modified and themed as a Gotham City Rail terminal in preparation for The Dark Knight. The new ride officially opened to the public on May 21, 2008. Six Flags New England and Six Flags México In February 2008, construction on the ride had started at Six Flags New England before all of the necessary construction permits were in order, leading building inspector Dominic Urbinati to issue a stop-work order. Without the proper construction documents, according to Urbinati, there was no way he could ensure the project met state building and safety codes. In March, the park was still faced with having to seek a new set of permits after several changes were made to the plans previously approved by city boards. Park management still hoped to open The Dark Knight Coaster by Memorial Day weekend, but still faced hurdles from the town of Agawam due to changes in design from the original plans. The Planning Board and the Conservation Commission later approved the proposed changes, such as a shift in the building's footprint to meet state fire safety codes, but the plans were rejected by the Zoning Board, which had previously granted a special permit for changes in height to the original plans. References to the ride were later
