Cobb is fortunate to have unparalleled transportation options.  Four major interstate highways traverse the county
(I-75, I-285, I-20 and I-575), as well as numerous state highways, two commercial rail lines (CSX and Norfolk Southern) and more than 2,000 miles of well maintained public roads.

Air Transportation
The center of Cobb is only 20 miles from Hartsfield-Jackson International Airport in Atlanta, the busiest passenger airport in the world. Twenty-three passenger and 19 cargo air carriers fly out of Hartsfield.  Being on the northwestern edge of Atlanta allows Cobb easy access to Hartsfield-Jackson via I-75, I-285 or surface streets, with a typical airport commute of 25-45 minutes.

McCollum Field in Kennesaw is the fourth-busiest airport in Georgia with an annual economic impact of more than $47 million to the local economy.  The field is home to more than 390 aircraft (both corporate and pleasure) and logs about 300 takeoffs and landings each day. McCollum Field is served by two full-service fixed-base operators and a fully-manned control tower.  

Cobb County continues to pursue additional improvements for McCollum Field. The airport runway is lengthening to 6,100 feet and has plans to widen the runway to 100 feet and construct an additional parallel taxiway.

McCollum Field is owned by Cobb County, operated by the County Department of Transportation and managed by a full-time, professional airport manager.

Public Transportation
Cobb Community Transit (CCT) operates a fleet of 75 buses on 17 routes, carrying 2.7 million passengers annually.  A reciprocal transfer agreement with the Metropolitan Atlanta Rapid Transit Authority (MARTA) links CCT services with regional employment, entertainment centers and Hartsfield-Jackson International Airport in Atlanta.

Transportation Alternatives
Cobb County is home to two Community Improvement Districts (CIDs) in the Cumberland and Town Center business markets. The CIDs levy a voluntary tax on commercial properties within the district.  A property owner-controlled Board of Directors in each CID decides how these funds will be utilized.  Policies mandated by the state legislation require that these funds be used to help finance transportation improvements and other business-oriented initiatives within the CID.  This innovative source of revenue ensures matching funds necessary for important road and public transportation improvements is available and serves to accelerate the timelines on the implementation of those projects.

The CIDs, along with county and state government, are aggressively pursuing expanded High Occupancy Vehicle (HOV) lanes, bus rapid transit and extensive interchange improvements on I-75 to help address the immediate and long term transportation needs of the community.

The CIDs each administer transportation management associations, Commuter Club in the Cumberland area and CobbRides in the Town Center district. These associations work to implement alternative modes of transportation for commuters.

Rail
The Norfolk Southern system operates a main line through the southern part of the county. Norfolk Southern’s Cobb operations include more than 18 miles of main line, almost 10 miles of second main, and eight miles of sidetrack. The company estimates that 35 trains per day run through Cobb County.

CSX Transportation also operates a main line through the center of Cobb, running from Atlanta to Chattanooga.
