ATLANTA — Drivers in Midtown Atlanta should prepare for weeks of traffic disruptions as the city begins a major sewer repair project along 10th Street and Piedmont Avenue.

The Department of Watershed Management says crews will remove and replace existing sewer mains to fix defects and increase capacity. Full lane closures will take effect in the work zone, which stretches from Peachtree Street NE to just east of Myrtle Street NE on 10th Street, and from 10th Street NE to 961 Piedmont Avenue NE on Piedmont.

Crews are scheduled to work Monday through Saturday, 7 a.m. to 7 p.m., with closures in place around the clock. City officials say the project is expected to run through mid-to-late October, weather permitting. Traffic control measures, including signs and detours, will guide drivers.

Local residents and businesses will still have access to essential services, though alternative parking will be required for vehicles normally left on the street.

Preparations began on Monday with partial lane closures on 10th Street between Juniper Street NE and Piedmont Avenue NE.
