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 alongside it in the areas the Legion controls.[1]


The I-40 connects many territories together and is a major trade route for caravans. It starts in North Carolina and goes through Tennessee, Arkansas, Oklahoma, Texas, New Mexico, Flagstaff in Arizona as well as intersects with Highway 93, twists around Bullhead City, and then enters California where it intersects with Highway 95 and then merges with I-15.


I-40 is mentioned only in Fallout: New Vegas.

Behind the scenesEdit

I-40 is based on the real world Interstate 40.


  1. Legion slave ledger: "Of particular interest is the fate of the Twisted Hair tribe of Arizona, who formed an alliance with Caesar to serve as his army's scouts during the conquest of that region. Once the Arizona wastes were pacified, the Legion turned on its erstwhile allies, stripped them of their tribal identity, and forced them into slavery. Those who resisted were crucified along the remains of I-40."
