History

The Arizona State Highway system was introduced on September 9, 1927, by the State Highway Commission (formed on August 11 of the same year). It incorporated the new federal aid system and also the U.S. Highway system. The 1927 plan included 27 state routes, most of which were simply dirt roads. Until 1942, the state route marker signs contained a Native American swastika, but were removed after the U.S.'s entry into World War II against Nazi Germany which had a reversed swastika as its emblem.

The modern system was introduced and adopted in the 1950s.
