Project Description

Project Information

The goal of this four-phase project is to provide an alternate route around one of the busiest roads in the Town Center area, Barrett Parkway. 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, scheduled for completion in 2018, will provide 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 a 5’ sidewalk will be 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.

Current Status

Phase two of the project received a $1.2M grant from Georgia Transportation Infrastructure Bank (GTIB) of the State Road and Tollway Authority (SRTA). Phase three of the project extends the Reliever over I-75 and improves Roberts Court between the Reliever and Barrett Parkway to the east. In June 2017, this phase received a $1.5MM grant from GTIB/SRTA. The Preliminary Engineering is currently underway.


The South Barett Reliever will cost $43,502,968 across three phases, which will be paid for in a joint effort between the Town Center CID, SRTA & GTIB, Georgia DOT and Cobb County DOT.
