Project Description

Project Information

The goal of this multi-phase project is to provide an alternate route around one of the busiest roads in the Town Center area, Barrett Parkway. When complete, the Reliever will connect from Barrett Lakes Boulevard to Chastain Meadows Parkway, bypassing Barrett Parkway and both major interstate interchanges.

Phase one included the realignment of Greers Chapel Road at its intersection with Barrett Lakes Boulevard and the widening of the roadway to four lanes, including a 20-foot raised median, from Cobb Parkway to Barrett Parkway. This phase of the project was completed and open to the public in 2010.

The second phase of the South Barrett Reliever project, completed in 2018, provides critical safety improvements with the realignment of Barrett Lakes Boulevard at Shiloh Valley Drive, including a two-lane roundabout at the intersection. To make pedestrian travel easier, crosswalks and 5’-10′ sidewalks were built around the roundabout, further enhanced with lighting and area landscaping. These improvements will increase public interest in walking in the area, previously considered too congested to be enjoyable for those on foot. In addition, a new pocket park is being designed by Kimley-Horn and Associates that, if installed, will further enhance the walkability and pedestrian safety of the area. The pocket park would include shaded seating and landscaping located on the southwest side of Barrett Lakes Boulevard and the new roundabout.

Current Status

The phase two roundabout, road realignment, landscaping and lighting is complete and the design of the pocket park is in progress. Phase three of the project extends the Reliever over I-75 and improves Roberts Court between the Reliever and Barrett Parkway to the east. This phase received a $1.5M grant from GTIB/SRTA in 2017 and ARC committed an additional $10.4M in 2018. The Preliminary Engineering is complete and Right of Way Acquisition is currently in progress.
