On our trip home from Memphis, we took a new route across Alabama. We drove Hwy 78 to Birmingham, and then south on the interstate to Montgomery. From there, we took Hwy 231 south to I-10, and from there, it was a straight shot home. Very nice drive, with no bad traffic. They have extended Hwy 78, exposing some wonderful new road cuts.
