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.

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.

After a year's work, the new ramps connecting SR 189 and I-19 are almost ready. And with them, a better day for commercial trucking and safety in Nogales.
