Invisible No More
On the way to Hartsfield-Jackson Atlanta International Airport — the nation’s busiest transportation hub — the air is filled with the hum of planes and the drone of cars as they speed toward departures. What you don’t hear is the rushing of water. Or even the trickle of a stream. Which is problematic, given that the headwaters of the 344-mile Flint River, which supplies water to hundreds of thousands of people across Georgia, are located at the airport. Or, more precisely, under the airport. A network of urban tunnels moves the Flint beneath the sprawling parking lots and runways.
