Steel Vengeance, formerly known as Mean Streak, is a steel roller coaster at Cedar Point in Sandusky, Ohio. The roller coaster, originally constructed by Dinn Corporation as a wooden roller coaster, was rebuilt by Rocky Mountain Construction (RMC) and opened to the public on May 5, 2018. It is a hybrid coaster, using RMC's steel I-Box track and a significant portion of Mean Streak's former support structure. Upon completion, Steel Vengeance set 10 world records, including those for the tallest, fastest, and longest hybrid roller coaster.
Mean Streak opened to the public on May 11, 1991, as the tallest wooden coaster in the world with the longest drop height. After more than 25 years of operation, Cedar Point closed Mean Streak on September 16, 2016, casting doubt and uncertainty regarding the ride's future. Over time, the park dropped subtle hints about a possible track conversion, which was officially confirmed in August 2017. It was marketed as the world's first hybrid hypercoaster – a wooden and steel roller coaster at least 200 feet (61 m) in height – and reemerged as Steel Vengeance. A minor collision on opening day led to a temporary closure and later modifications from RMC.
