The Diamondback is currently under construction at Kings Island, but the last section of track was put in very recently, and the coaster will be ready to go when the park opens for the Summer 2009 season. More info? Of course:
The tallest, fastest and meanest roller coaster to hit Kings Island unleashes its fury with over 5,200 FEET of steel track. 230 FEET TALL, this monster twists and turns through 10 ACRES of terrain, wooded hills with a spectacular splashdown ending to give you the ultimate thrill, without the venom! Diamondback will open APRIL 2009.
