The South's transportation story begins and ends with Hartsfield-Jackson Atlanta International Airport — the busiest airport in the world. Atlanta's central location, combined with Delta Air Lines' massive hub operation, makes it the most connected airport on the planet. More passengers pass through Atlanta each year than through any other airport, including London Heathrow, Dubai, and Tokyo Haneda.

The Gulf Coast is home to some of America's most important ports. The Port of Houston is the largest in the US by foreign waterborne tonnage, driven by the petrochemical industry and Texas's export economy. The Port of New Orleans sits at the mouth of the Mississippi River, a strategic position that has made it a trade hub since the French colonial era. The Port of Savannah has been the fastest-growing port in the country, benefiting from modern supply chain shifts.

The South has also contributed iconic transportation landmarks. Florida's Overseas Highway leaps across 42 bridges to connect the mainland to Key West — one of the most dramatic drives in America. The Sunshine Skyway Bridge across Tampa Bay is an architectural marvel. The Daytona International Speedway in Florida and the Dallas/Fort Worth International Airport in Texas represent the South's love of speed and scale.

This quiz covers the transportation networks that make the South move — from the world's busiest airport to the Gulf Coast's mighty ports to the scenic roads and bridges that make the region unforgettable.
