Who to call

Roads

County road work, closures and paving are on the Cobb DOT closure dashboard and our road construction page. Current projects include the Lower Roswell Road median and multi-use trail, scheduled to finish Nov. 19, and the planned Johnson Ferry Road at Shallowford Road intersection rebuild.

For I-75, I-285 and state routes, GDOT posts incidents, construction and cameras on the Georgia 511 map. Cobb also runs live traffic cameras. Toward downtown Marietta, the Marietta Square Farmers Market’s directions use I-75 exit 265 and North Marietta Parkway.

CobbLinc buses

CobbLinc, run by Cobb DOT, has two transfer centers (Marietta and Cumberland), nine local routes, a free circulator and a microtransit zone, according to the county’s routes page. Its system map (PDF) shows every route.

Route 50 is the line that touches East Cobb. It runs between the Marietta Transfer Center and the Cumberland Transfer Center by way of Delk Road at Powers Ferry Road, Powers Ferry Road at Windy Hill Road and Akers Mill Road at the Galleria, according to its schedule. Weekday trips leave Marietta every half hour from 6 a.m.

Microtransit. CobbLinc Go, the on-demand service, covers South Cobb, and the county held hearings this summer on adding an Acworth-Kennesaw zone. Neither zone includes East Cobb, according to the county’s microtransit notice.

Fares. CobbLinc uses the regional Breeze system. Riders can tap a bank card, phone or watch on the bus validator, or use a Breeze card, which also works in Apple Wallet, the county’s fares page says.

Holidays. CobbLinc does not run on New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day or Christmas Day.

Getting to MARTA and the airport

CobbLinc’s connections page lists the links to MARTA:

  • MARTA Route 12 stops at the Cumberland Transfer Center and runs to MARTA’s Midtown Station by way of Cumberland Mall and Georgia Tech.
  • CobbLinc’s Express routes and local Routes 10, Rapid 10, 25 and 30 connect to MARTA stations.

From MARTA, trains serve Hartsfield-Jackson Atlanta International Airport; check MARTA’s airport service page for current service alerts.

Cobb County’s own Cobb County International Airport, McCollum Field, is a general aviation airport run by Cobb DOT. It has no commercial airline service, the county says.

Trails, biking and walking

  • Chattahoochee River trails: Cochran Shoals, Sope Creek, Johnson Ferry and Gold Branch, with a $5 daily National Park Service pass. MARTA Route 148 serves the Powers Island entrance from Sandy Springs Station at weekday peak hours, the Park Service says.
  • County trails: see Cobb’s trail map and our parks and trails guide.
  • Sidewalks: neighborhoods without sidewalks can petition Cobb DOT for a sidewalk district. At least 75% of lot owners must approve, and each lot pays a share of the cost, according to the county’s bike and pedestrian page.

Parking

East Cobb has no downtown and no city parking rules; parking is in shopping center lots and at parks. Avenue East Cobb says it has surface parking off Roswell Road. The Chattahoochee River trail lots require the National Park Service pass. For events on the Marietta Square, use the city’s downtown Marietta parking map.

What this means for you

  • Plan on a car for most trips; check Georgia 511 before rush hour.
  • If you work in Cumberland or Midtown, Route 50 and MARTA Route 12 are the transit links.
  • Buy the $40 annual river pass if you use the Cochran Shoals lots often.
