Part of Mt. Troy Road in Reserve is down to one lane Friday because of a landslide, according to the Allegheny County Department of Public Works.
The southbound lane is closed around the 2800 block, between Fornof Lane and Ampere Street.
Flaggers will direct traffic until the installation of a new temporary traffic signal.
Officials don’t know when the landslide damage will be repaired and the southbound lane will reopen.
