Nadine Road in Penn Hills is expected to remain closed for about three more weeks, during stabilization of a hillside.
The entire road from Allegheny River Boulevard to Lincoln Road was closed May 2 after a landslide. Traffic is being detoured via Sandy Creek and Verona roads.
Duquesne Light, which completed replacement of a transmission line along the road last year, has hired a contractor to shore up the hillside, spokesman Brian Knavish said.
“While the investigation into the cause of the landslide is ongoing, we do not believe it is the result of our construction or any other Duquesne Light work. We’ve hired a contractor to make repairs as part of our efforts to be a good corporate citizen and community neighbor,” he said.
