East Cobb Pipeline Project Updates

November 11, 2016:

The Cobb County-Marietta Water Authority’s East Cobb Pipeline project has surpassed the halfway point of construction.  With over 18,000 feet of new 54” diameter water main in the ground, crews continue installation along two challenging sections of roadway.  By mid-February of 2017, one crew plans to complete pipeline construction and temporary paving between Paper Mill Road and Old Canton Road along Terrell Mill Road. This pipe-laying crew should be able to maintain two-way traffic at all times, although there will be several traffic shifts and minor disruptions to traffic flow as work progresses. The second crew will be working along Lower Roswell Road from near Indian Hills Parkway/Cove Drive towards the crossing of Sope Creek (near Shadowlawn Rd.).  Due to the smaller 3-lane width of roadway and for safety of the crew and travelling public, traffic will be restricted to one lane in the immediate work zone from 9am-4pm daily.  As work progresses, alternative work schedules will be considered for this section.  

For more information, please visit CCMWA’s website.  For questions or concerns, please call the project hotline at 770-514-5301.  CCMWA appreciates your continued patience as construction progresses.
