Kings Dominion is retiring its Shockwave stand-up roller coaster.
The Virginia theme park announced Thursday that Shockwave will close Aug. 9 to make way for future growth in the park's Candy Apple Grove section.
The coaster has carried more than 22 million riders since it opened at the park in 1986.
Kings Dominion -- located north of Richmond in Doswell -- said Shockwave is the oldest operating stand-up coaster in the nation. It reaches speeds of 50 mph and is 95 feet tall at its highest point.
The park plans to announce special events for the closure of Shockwave on its social media accounts.
