PITTSBURGH (WPXI) – Kennywood’s newest roller coaster, the Steel Curtain, shut down early Saturday due to technical difficulties, according to a post on the park’s Facebook page. The park said crews will be working to have the ride reopened for Sunday morning. In the Facebook post, the park said, “Part of the process with a brand-new, big-time ride!” Saturday was the first day the new roller coaster was open to the public. At 220 feet, the coaster is now Pennsylvania’s tallest, according to Kennywood. It also includes the world’s tallest inversion, at 197 feet high. Part of a collaboration with the Pittsburgh Steelers, The Steel Curtain is the flagship attraction of a themed section of Kennywood that’s being called “Steelers Country.”
