Subsidence causes road closure of Plum's Center Road
Work was expected to start this week on a portion of Center Road in Plum that remains closed to traffic because mine subsidence was causing it to collapse, Allegheny County officials said Monday.
Stephen Shanley, the county's public works director, said on Monday that a repair plan involves pouring a grout mixture or thin mortar into the area affected by the subsidence that is south of Trestle Road to north of the Boyce Park main entrance on Center Road.
The work was expected to begin on Wednesday and take several days to complete, Shanley said.
Shanley said the county is working with both the Pennsylvania Department of Environmental Protection and the Bureau of Abandoned Mine Reclamation to fix the roadway.
Shanley said the grout mixture is expected to minimize the chances of further collapse of the roadway.
The portion of Center Road affected by the collapse has been closed since March 25. Officials said a county public works supervisor noticed a hole near the side of the road, investigated further and determined the problem was mine subsidence.
Jersey barriers are in place across the road north of the Boyce Park main entrance and south of Trestle Road preventing through access on Center Road, officials said.
Plum police advised drivers to avoid Monroeville Trestle Road between Old Frankstown Road and Saltsburg Road. Traffic should detour by using Saltsburg Road to Pierson Run Road to Old Frankstown Road, according to the county.
