Rockwood Drive closure to begin Monday, Oct. 17


Rockwood Drive in Marietta, between Jamerson Road and Gray Rock Drive, will be closed to traffic Monday, Oct. 17 through Monday, Nov.14. 

The existing 48-inch corrugated metal pipe on Rockwood Drive has failed, causing settlement in the roadway.  This project includes replacing the existing pipe with a 48-inch reinforced concrete pipe, constructing new headwalls and repaving the failure area.

Please use detour routes to avoid the closure location.
