From the ADOT Archives: Dust Storm Warnings

Dust storm warning on overhead sign

Back then, ADOT couldn’t utilize Twitter, Facebook or a blog to advise drivers of an impending dust storm, but the agency did have changeable message signs on I-8 and I-10 that were used to signal “Dust Storm Alerts” and refer drivers to the radio stations where dust storm advisories could be heard.

Workers set up dust storm warning on overhead sign

Crews install a "dust storm alert" sign on I-10 (6/2/76).

So, while there were no #HaboobHaikus being written in 1976 (at least that we know of), there was still a need – as there is today – for ADOT to communicate important safety messages with motorists.
