Hartsfield–Jackson is ranked as the world's busiest airport, both in passengers and number of flights.

In 2011 it accommodated 92 million passengers (252,000 passengers daily) and 923,991 flights. Atlanta serves as a major hub for travel throughout the Southeastern United States

The airport today employs approximately 55,300 airline, ground transportation, concessionaire, security, federal government, City of Atlanta and Airport tenant employees and is considered the largest employment center in the state of Georgia. With a payroll of $2.4 billion, the airport has a direct and indirect economic impact of $3.2 billion on the local and regional economy and a total annual, regional economic impact of more than $19.8 billion

By the turn of the century, Delta Air Lines had become a true global carrier—an extraordinary progress from three six-seat monoplanes and a few pilots serving four Deep South cities in 1929. As of mid-2004 Delta had access to more than 494 cities in 86 countries.

The system is named for President Dwight D. Eisenhower, who championed its formation.

The cost of construction has been estimated at $425 billion (in 2006 dollars),

making it the "largest public works program since the Pyramids."

The system has contributed in shaping the United States into a world economic superpower and a highly industrialized nation.

General Lucius D. Clay, a native son of Marietta, GA, was one of the people that helped make the interstate a reality. Due to him I75, I85 and I20 all run through Atlanta insuring it would be a hub for the south.

In the numbering scheme, east-west highways are assigned even numbers and north-south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north.

Numbers divisible by five are intended to be major arteries among the primary routes, carrying traffic long distances. Major north–south arterial Interstates increase in number from I-5 between Canada and Mexico along the West Coast to I-95 between Canada and Miami along the East Coast.

Georgia's rail history began in the 1830s as America was just beginning to build a network of tracks. By 1850 Georgia had the most rail miles of any southern state. More than a century and a half later, it continues to be a railroad leader.

In several cases county seats were moved to be on the railroad. In Bartow County the seat moved from Cassville to Cartersville.

ADJUSTED FOR INFLATION.

The classification of railroads in the U.S. as Class I, II or III was started by the Interstate Commerce Commission with its report for the year ending 30 June 1911. Initially Class I railroads were defined as railroads with annual operating revenue of at least $1 million while Class III railroads had less than $100,000.

Class I railroads had minimum carrier operating revenues of $346.8 million (USD) in 2006, $359 million (USD) in 2007, $401.4 million (USD) in 2008 and $378.8 million (USD) in 2009.

Georgia Ports Authority (GPA) Executive Director Curtis J. Foltz announced today the results of a study that confirms Georgia’s deepwater ports continue to be one of the state’s strongest economic engines, fostering the development of virtually every industry.

According to the study, Georgia’s deepwater ports support 295,422 full- and part-time jobs, which is nearly seven percent of Georgia’s total employment, or 9,000 additional jobs since the last study was conducted in 2006. This means that one job out of every 15 in Georgia is in some way dependent upon its ports

In 2005 Savannah was the and nation’s fastest growing port, with a compound annual growth rate of 16.5 percent; the national average was 9.7 percent.

The Port of Savannah offers more than 9,800 feet of linear berthing space, which is a 20 percent increase in capacity and is the nation’s largest single terminal container facility.

Meanwhile, the Port of Brunswick has carved a lucrative niche for itself in agricultural cargo and car shipments. A massive rail expansion project recently approved for this port will double its rail capacity.
