East Cobb Pipeline Project Updates

July 28, 2016:
Pipeline crews closed the two southbound lanes of Terrell Mill Road from Delk Road to just past Powers Ferry Road. Northbound traffic on that portion of Terrell Mill is proceeding normally. Southbound drivers are being routed to Delk Road to get to Powers Ferry. The traffic lights in the area have been adjusted to accommodate this shift in traffic. It is expected this portion of Terrell Mill will reopen in early September, barring weather delays or other complications. Stay up-to-date on project construction and traffic impact through our website, CobbCommute.org, Twitter (@waterCCMWA) and the project hotline (770-514-5301).
