(WPXI) – Ahead of this 4th of July weekend, two popular rides at Kennywood Park are closed for repairs. Kennywood General Manager Mark Pauls provided a statement confirming the Steel Curtain coaster is closed and they’re working to reopen it as soon as possible — although no timeline was given. Pauls said the record-setting ride is the first of its kind, and requires additional maintenance to best ensure guest and team member safety, which is their top priority. The Thunderbolt is also closed, but Pauls said they have a goal of opening in time for the holiday weekend.
