Contra Costa County’s Public Works Department on Tuesday closed Marsh Creek Road between Deer Valley Road and Pine Lane in Clayton because of a large sinkhole forming.
Because of the recent rains, a culvert under Marsh Creek Road near Morgan Territory Road has failed and a potential sinkhole is starting to form. Public Works crews are trying to determine the extent of damage and necessary next steps.
Drivers approaching the area on Marsh Creek Road will be turned around at either Deer Valley Road or Pine Lane. Local residents living between Pine Lane and Deer Valley Road will be able to access their homes.
