Cal-Nev-Ari was created in the mid 1960s by Nancy & Slim Kidwell, who acquired a 640 acre section of land from the U. S. Government and commenced development of an airport-based community. In addition to the FAA designated Kidwell Airport, the community has grown over the years to include a casino, motel, RV and mobile home parks, convenience market, and over 100 residential lots.
A consequence of the September 11th terrorist attacks is that trucks and motorhomes are no longer allowed to pass over Hoover Dam. As a result, they have now been routed down highway 95 and through Cal-Nev-Ari in order to get to Arizona.
