They're at least going to have the land available to make the I-11/I-40 interchange in Kingman a complete "Y" interchange.
I wouldn't think hurricane evacuation routes would be important for NW AZ. When I was a kid my dad was stationed at MCAS Yuma; we were close enough to the Gulf of California that we experienced tropical storm force winds a couple times via hurricanes coming ashore in Baja California and moving into Arizona. Still, it wasn't all that big a deal compared to other far more hurricane-prone places we lived.
