The work to repair Nadine Road in Penn Hills and its retaining wall will begin Aug. 20, the Allegheny County Department of Public Works said.
The section of the road between Allegheny River Boulevard and Lincoln Road has been closed since July 12 following storms that overturned the wall and caused a portion of the road to collapse.
The work, which includes removal of the overturned wall, excavation, construction of a new retaining wall and road repairs, is expected to last two months, public works said.
Traffic has been detoured using Allegheny River Boulevard, Sandy Creek, Verona and Lincoln roads.
