Circle 75 Parkway, from Cobb Parkway to Heritage Court, will be closed to through traffic from Thursday, Jan. 19, to Wednesday, Jan. 25, 2017, for work on the I-285 Multiuse Bridge. To access Circle 75 from Cobb Parkway, motorists should take Windy Ridge Parkway. Access to the 900 building and Hampton Inn will be maintained at all times. Signage and traffic control devices will be in place to direct drivers.

The 1,100-foot I-285 Multiuse Bridge, which is slated to be operational by April 2017 and entirely complete later in the summer, will span Galleria Drive, I-285 and Circle 75 Parkway to provide pedestrian and shuttle access from the Cumberland Galleria to SunTrust Park and The Battery Atlanta.

Three transportation projects in Cobb County were recognized for their designs at the annual Georgia Partnership for Transportation Quality Preconstruction Design Awards during the 2016 Georgia Transportation Summit held Nov. 30, 2016, in Athens, Ga.


The Cobb County Department of Transportation today announced a data-sharing partnership with Waze (, the free, real-time crowdsourced traffic and navigation app powered by the world’s largest community of drivers.

The two right lanes of the I-285 westbound ramp to I-75 northbound will be closed Sunday, Nov. 20, 2016, from 5 a.m. to 8 p.m. (An additional closure may be required Monday, Nov. 21, 2016, from 9 p.m. through 5 a.m. Tuesday, Nov. 22, 2016, to complete the work.) The right lane from I-285 eastbound to I-75 northbound will be closed to allow traffic to shift over from the double lane closure. Signage and traffic control devices will be in place to direct drivers.

These lane closures will allow for the removal of a beam from the Windy Ridge Parkway Bridge on the north side to prepare for girder installation the following week. The Windy Ridge Parkway Bridge project consists of the widening of the existing bridge over the I-75 and I-285 ramps to provide enhanced pedestrian accommodations and greenway space. Completion is expected in 2017.

A public information open house for the Cobb County Department of Transportation (CCDOT) Windy Hill Road – Terrell Mill Road Connector project will take place Nov. 15, 2016, from 5 to 7 p.m. at Brumby Elementary School in Marietta.

A court reporter will be available to record public comments. 

Rockwood Drive in Marietta, between Jamerson Road and Gray Rock Drive, will be closed to traffic Monday, Oct. 17 through Monday, Nov.14. 

The existing 48-inch corrugated metal pipe on Rockwood Drive has failed, causing settlement in the roadway.  This project includes replacing the existing pipe with a 48-inch reinforced concrete pipe, constructing new headwalls and repaving the failure area.

Please use detour routes to avoid the closure location.

Beginning Sept. 30, 2016, the ramp from Windy Hill Road eastbound to I-285 westbound will be closed nightly from 9 p.m. to 5 a.m. through Oct. 3, 2016, for work on the Windy Ridge Parkway Bridge project. Drivers looking to take the westbound ramp to I-285 will be directed to I-75 southbound. Message signs, as well as a Cobb County police officer, will be in place to announce the ramp closure and redirect motorists. The ramp from Windy Hill Road to I-75 southbound will remain open.

Beginning Wednesday, Sept. 7, 2016, the right lane for eastbound travel on Windy Hill Road at the I-75 overpass will close indefinitely as the westbound lane on the north side of the bridge reopens. This 24-hour lane closure will cause significant traffic congestion and delays at different times throughout the day. Following this traffic shift, the lane configuration for eastbound traffic across the I-75 bridge will be two through lanes and one left turn lane to I-75 North. Construction work in the area will take place weekdays from 9 a.m. to 4 p.m. Drivers are strongly encouraged to use alternate routes.

Cobb County transit riders will enjoy better service to the Cumberland region and downtown Atlanta on CobbLinc beginning Sept. 6, 2016.

The county’s bus service, CobbLinc, is adding a new route 25 from the Cumberland area to MARTA’s Hamilton E. Holmes rail station and updating several other routes.

CobbLinc is the new name for buses and other transit services provided by Cobb Community Transit. Today’s announcement includes expanded coverage, improved safety and a quicker ride for commuters using CobbLinc. All are part of a Cobb transit improvement plan reflected in the new CobbLinc branding.

After Aug. 29, 2016, motorists traveling along Windy Hill Road will no longer have access to the center turn lane, from U.S. 41/Cobb Parkway to Circle 75 Parkway, while the lane is permanently closed and converted into a raised median. Motorists will be able to make left-hand turns only at signalized intersections.

The lane-to-median conversion along the heavily-traveled, half-mile stretch of road is one of the $48 million traffic and safety improvement projects along the 1.43-mile stretch of Windy Hill Road, from U.S. 41/Cobb Parkway to Powers Ferry Road.

The Georgia Technology Authority (GTA) has awarded Cobb Commute top honors in Georgia’s 2016 Technology Innovation Showcase. The web-based application, provided via collaboration between the Cobb County Department of Transportation and Information Services Department, offers up-to-date traffic conditions for local commuters. It is one of eight projects that will be recognized at a luncheon during the Georgia Digital Government Summit on September 29, 2016, in Atlanta. Cobb Commute is the only county project to earn top honors in the showcase.

On June 22, 2016, the State Road and Tollway Authority Board (SRTA) approved a $1,600,000 grant to fund Cobb County Department of Transportation improvements in the Six Flags area. The project seeks to improve mobility on Riverside Parkway from the I-20 EB off-ramp to Six Flags Drive by realigning an intersection and improving sidewalks, traffic signals and signage. Employees and guests to Six Flags Over Georgia also will benefit from increased accessibility.

Plaques honoring Thomas E. "Skip" Spann were placed along the Skip Spann Connector on Tuesday, June 21, 2016. The connector, the first lighted bridge in the county, increases safety for pedestrians and bikers while reducing I-75 and Chastain Road congestion. Spann, founding chairman of the Town Center Community Improvement District, inspired growth and change in Cobb County and served on the TCCID Board of Directors until his passing in 2012.

A section of Paces Ferry Road, from Paces Mill Road and Cochise Drive, will be closed, Sunday, June 26, beginning at 10 a.m., while Georgia Power relocates several utility poles around the Cobb County Vinings fire station. The closure is expected to last approximately eight hours. To insure the safe and efficient relocation of poles, Georgia Power must turn off power to 18 residential customers in the immediate vicinity. Those customers are being contacted directly. No business customers will be impacted. Please use New Paces Ferry Road as a detour during construction.


The Cobb County Department of Transportation received more than $8 million in grants through the state-funded GO! Transit Capital Program on Wednesday, June 22, 2016. Gov. Nathan Deal and State Road and Tollway Authority (SRTA) Executive Director Chris Tomlinson announced awards for 11 transit projects, including two for Cobb County.
