History will most likely remember the late Justin Herman, Arizona Highway Department director from 1956-1973, as the energetic leader who shepherded in the modern state freeway system, including the Black Canyon (I-17), Superstition (US 60) and Maricopa (I-10) freeways.

This century-old other bridge over the Salt River deserves some recognition.

Our weekly challenge features a unique Arizona image and this week is no different.

Did you know that two highway workers have been injured this year while working on projects? That's why National Work Zone Awareness Week is so important. ADOT's director shares his thoughts.

ADOT has been posting to its blog for 10 years now, but the entire time we've had one mission - to give you the inside look at what we do and how and why we do it.

A year ago we introduced AZMVDNow.gov to help you complete MVD services on the Internet. But what about ServiceArizona.com? This is how the two work together to get you out of the MVD and onto the road.

Join our weekly challenge that test's your Arizona knowledge!
