After years of planning and plenty of rush-hour grumbling, the South Barrett Reliever quietly opened last Thursday, giving Cobb County drivers in the Town Center area a fresh east-west route over I-75 that skips the famously jammed Barrett Parkway interchange. Local officials are betting the new connection will smooth daily commutes around the Town Center shopping and office hub and take some strain off the existing ramps.
County leaders marked the occasion with a ribbon-cutting on top of the new bridge, touting the project as a “transformative investment” that creates a direct link from Cobb Parkway to Barrett Parkway while avoiding the Barrett Parkway/I-75 interchange, according to Cobb County. The county release describes the reliever as a long-term, multimodal fix for the Town Center district, made possible through a mix of federal, state and local partners.
Cobb transportation director Drew Raessler told Atlanta News First that Barrett Parkway currently handles about 60,000 vehicles a day and that the new route could peel off around 12,000 of them, roughly a 20 percent traffic drop. He cast that shift as a way to boost day-to-day reliability for both commuters and freight moving through the Town Center corridor.
What the project includes
The Town Center Community Improvement District pegs the total investment at more than $62 million and says the work delivers a signature bridge spanning I-75 and the Northwest Corridor Express Lanes, modern multi-lane roundabouts, a four-lane divided roadway, sidewalks, bike lanes and a shared-use path. The reliever is described as the southern arc of "The Loop," a 7-mile complete-street concept meant to tie together the district’s major corridors. Town Center CID
Cobb Chairwoman Lisa Cupid praised the effort during the ceremony, calling it “a long time coming” and “worth every moment of the wait,” as noted in the county’s write-up. The same county release also highlights project partners including the Atlanta Regional Commission, the State Road & Tollways Authority, the Georgia Department of Transportation, Arcadis and C.W. Matthews Contracting Co., and characterizes the reliever as a potential spark for future redevelopment. Cobb County
How drivers are reacting
Early feedback from nearby residents leans optimistic, with some saying the new route already feels quicker during the usual choke points. In interviews with Atlanta News First, one driver said the bridge made “life easy,” while another pointed to simpler access to I-75 as a welcome change.
What to watch next
Transportation planners like to remind everyone that a new connection can reshuffle traffic in ways that only become clear over time, and this project is no exception. Local observers will be watching to see whether the reliever delivers lasting relief or mostly shifts congestion to new spots. Urbanize Atlanta previewed the opening with a call for follow-up monitoring, and WSB-TV noted that crews were still putting finishing touches on the bridge just ahead of opening, a reminder that the work continues after the ribbon comes down.
Officials say they plan to track traffic patterns and safety data as the reliever becomes part of drivers’ regular routines, with the CID pointing to targets such as better travel-time reliability and lower crash risks. They also frame the bridge as just the opening move in a broader rethink of how Town Center functions, with additional streetscape upgrades and redevelopment efforts expected to keep moving forward alongside the new link.
