A road in New Sewickley Township remains closed this noon, more than 15 hours after a tractor-trailer crashed Tuesday afternoon. The crash was reported just before 4 p.m. Tuesday on Freedom Crider Road, a 4-mile stretch of which was closed at one time. The closure is in place between Route 989 and Crows Run Road. Officials said the closure was needed after a tractor-trailer crashed off the road, taking out part of the guide rail and sliding down a hillside. No one was injured in the crash. Officials say the road will likely not reopen until later today, once crews from PennDOT can assess the situation.
