East Cobb Pipeline Project Updates

March 3, 2017:

East Cobb Pipeline Update

Cobb County-Marietta Water Authority’s East Cobb Pipeline project has continued to make progress this winter. Crews continue working in two locations along Lower Roswell Road, both moving towards the Sope Creek crossing. Crew #1 is continuing pipe installation in a northeastern direction from Hillingdon Court. Crew #2 is working in a southwestern direction near Dickerson Rd. 

*IMPORTANT NOTICE * -  Paving near the one work zone between Indian Hills Pkwy and Anniston Ct. is anticipated to begin the week of March 6th.  Due to the smaller 3-lane width of roadway along Lower Roswell Road, for safety of the crews and travelling public, traffic will be restricted to one lane in the immediate work zones from Tuesday, March 7th 9 AM through Thursday, March 9th 5 PM. Paving activities will occur during extended daytime hours on Tuesday and Thursday. Paving on Wednesday will occur overnight. Traffic Control  will be in place 24 hours a day. Due to the extent of pavement reconstruction activities and safety of the public it will be necessary to restrict traffic to  one lane during this time period.

Suggested alternate route includes Old Canton Road, Roswell Road and Johnson Ferry Road.
