Diamondback

Diamondback is a steel roller coaster located at Kings Island in Mason, Ohio. Manufactured by Bolliger & Mabillard , the ride opened in 2009 as the first hypercoaster to feature a splashdown effect and the first B&M roller coaster at Kings Island. It is located in Rivertown just behind International Street and the Eiffel Tower. Diamondback was the biggest investment in Kings Island’s history at the time, costing $22 million to build, but that figure was surpassed in 2014 by Banshee. The coaster features a 230-foot lift hill with a 215-foot drop and a maximum speed of 80 mph . It is similar to Behemoth at Canada's Wonderland in statistics, layout, and seating.

Construction of Diamondback began on October 11, 2007, with the removal of a tree. Swan Lake was drained and filled with concrete before opening day in 2008; this would become the location of Diamondback's splashdown element. Kings Island started teasing visitors during the Fourth of July weekend in 2008 with signs saying, "Ride Sally ride" and "Steep incline ahead." Diamondback was announced on August 6, 2008 as the largest investment in Kings Island history. The ride was topped off with the 230 foot lift hill on October 30. The last piece of track was installed on January 26, 2009. Testing began the following month. Diamondback officially opened on April 18, 2009. Diamondback reached a milestone of one million riders in July 2009, and another milestone of ten million riders in July 2014.
