I-40

The I-40 or Interstate 40 is a freeway in the former United States. It was used to serve vacationers and commuters alike before the Great War. By 2281, Caesar's Legion has used the old highway to transport its legionaries and supplies as well as using it to display crucified prisoners and slaves such as the Twisted Hairs along it in the areas the Legion controls.
