Batman: The Dark Knight was announced to the public on February 6, 2002, though construction had started in September 2001.
After construction and testing was completed by Martin & Vleminckx, the ride officially opened on April 20, 2002.

In 2007, Six Flags announced three The Dark Knight Coaster roller coasters would be built at Six Flags Great Adventure, Six Flags Great America and Six Flags New England.
Because Batman: The Dark Knight's name was so similar to the new roller coaster, it was temporarily renamed Batman: The Ride to avoid confusion with the upcoming attraction.
However, as construction on the new roller coaster progressed, the city of Agawam forced Six Flags to stop construction after it was discovered the park had not received the appropriate construction permits.
In April 2008, Six Flags cancelled the project due to the delays and so the name was reverted to Batman: The Dark Knight.
