There isn’t much here — only a sign on each side that faces the traffic to note the spot and a slight widening of the shoulder to stop for a picture — but it’s an important marker. It is the Eastern hydrological divide, meaning that water spilled on one side would eventually flow to the Atlantic Ocean and water spilled on the other would flow to the Gulf of Mexico. This is not the spot where Eastern and Central time are divided — that’s about 60 miles west, somewhere in Tennessee. In the 1700’s, this was the line that split the British colonies in North America with those of the French. There wasn’t an Interstate through here back then, of course. You’ll also note that this is where, heading west, the lanes merge from three into two because the trucks aren’t going slow and climbing the«mountains» anymore. And from the west, heading east, they need to start checking their brakes because the road has a pretty steep grade, dropping from 2786 feet above sea level here to 1500 and less over the next few miles.
