South Barrett Reliever – Phase 3
- One of three phases that will help reduce congestion on Barrett Parkway by 22%
- Crossing over I-75 and the Managed Lanes
- One of the largest infrastructure projects to date

The South Barrett Reliever is a road realignment project to give drivers an alternate route around Barrett Parkway, one of the busiest corridors in Town Center. In Phase 3, the roadway will continue from where Phase 2 ended, then reach across I-75 and the Managed Lanes and extend to Barrett Parkway via Roberts Court.
The project was the result of the CID’s Barrett Parkway Reliever studies (which was also the catalyst for the Big Shanty Connector). This stretch is part of a four-phase initiative to form a new southern bypass from Cobb Parkway and Greers Chapel Road to Chastain Meadows Parkway, crossing both I-75 and I-575.
Phase 3’s complete east-west stretch will improve connectivity to Town Center’s prime areas of growth. With additional corridor improvements like bike lanes and crosswalks, the public will have a new opportunity to walk and bike where connections previously did not exist. By facilitating interest in these alternative transportation options, the Reliever is expected to decrease traffic during peak hours by 22%.

CID consulting partner Arcadis is conducting a study to determine the feasibility of a fourth phase for the Reliever. The study will analyze anticipated traffic and safety improvements in an extension of the corridor over I-575 to an undetermined point to the east. It will be completed in 2020.
