Kings Island amusement park is removing a wooden roller coaster plagued by problems since opening 12 years ago. Kings Island will begin dismantling the coaster this summer to make room for future expansion. A park statement does not say what will replace it. The ride was billed as the world's tallest and fastest wooden roller coaster when it opened. The track rose to a 218-foot peak with trains reaching speeds of 78 mph. It closed for nearly a year for reconstruction after more than two dozen people were injured in a 2006 accident. The park closed it again in 2009 after a woman reported she was injured. The park did not reopen it even though state inspectors found no irregularities.
