A portion of Route 51 (McGovern Boulevard) in Moon Township is closed in both directions due to a major landslide reported late last night. The heavily traveled roadway is closed between Purdy Road and Stoops Ferry Road after the landslide downed trees and power lines, according to Moon police. The landslide was reported shortly before midnight. Crews from PennDOT are on the scene to oversee repairs. Peoples Gas and Duquesne Light were also called in, police said. Power was restored around 5:30 this morning for about 600 Duquesne Light customers. Northbound drivers are being advised to turn left onto Flaugherty Run Road to avoid the closure; southbound drivers should take Brodhead Road.
