ADOT does a lot of digging, but we have to be very careful not to disturb any historic (or prehistoric) sites that could be at a potential project site. That’s where the ADOT Historic Preservation Team comes in. As a part of ADOT’s Environmental Planning Group, this team is in place to make sure all ADOT projects adhere to state and federal historic preservation laws.

Ordinarily, an excavation like this would have to wait until ADOT had a highway construction project to work on (lane widening, new freeway construction, etc.) -- that way the cost would be included in the project’s scope. But this site’s a little different…

ADOT installed the 160-ton, 600-foot long bridge over two nights in June next to the Central Arizona Project (CAP) canal.

A new annual report shows that the number of fatalities on Arizona’s highways and local roads increased during 2011… According to ADOT’s most recent “Crash Facts” report, 825 people lost their lives in motor vehicle crashes in the state last year – an 8.7 percent increase from last year’s figure.

you were able to “virtually” drive on the new stretch of road and see the views around your neighborhood? Imagine if you could get a glimpse of what a freeway ramp would look like from the vantage of the road?

We’ve all been there... Sitting in traffic, moving slowly and wondering if we’ll ever get past the incident that’s causing the delay. Thousands of motorists experienced that scenario yesterday during a busier-than-usual morning rush hour.

Here we are, past the halfway point on the I-17/Cordes Junction interchange project and it’s clear that work is really moving along! At least, it’s clear if you drive the area frequently, or if you watched this video back in February. Crews have been busy since then, as you can see above.

“Utility relocation” is a phrase that might sound familiar if you get our traffic alerts. A fairly self-explanatory term, it refers to the moving of underground or overhead utilities (things like cable, telephone, electricity, sewer, water or gas lines).

We’re looking for your feedback on a transition plan that’s designed to outline in detail how ADOT plans to ensure safe access to all of its facilities for all individuals.

West Valley drivers have, no doubt, already noticed there’s a lot happening over on the I-10/Loop 303 interchange project, but for the rest of you, we thought we’d provide a quick update…

Social media is all about being social, which is exactly why we enjoy our Facebook page so much…

ADOT and its employees earned honors at the AAMVA 2012 International Conference held last month in North Carolina...

Construction had only recently started back when we first checked in on the SR 64 highway improvement project… That was about a year ago. Since then, well, just take a look at the video above and see for yourself how much this project has transformed the area’s landscape!

To say that ADOT crews were busy Tuesday would be a bit of an understatement. Heavy overnight and morning rains across the state started the day off with extremely slow commutes throughout the metro areas … but nothing like the messes that would happen later in the day …

In the world of transportation, rarely does anything stay the same.

It may look like something out of the latest hi-tech spy movie, but our newly refurbished Traffic Operations Center is wonderfully real. This state-of-the-art electronic data hub is located in Phoenix and allows ADOT staff to keep a watchful eye on traffic conditions around the state.

What is a roadway departure crash? By definition, a roadway departure crash is a non-intersection crash that occurs after a vehicle crosses an edge line or a centerline, or otherwise leaves the traveled way.

Hard to believe, but 10 years have passed since the first AMBER Alert was issued in Arizona… In that time, 70 AMBER Alerts have been issued in the state and all but one – the ongoing Jhessye Shockley case – were resolved successfully through a partnership between local radio and television broadcasters, law enforcement, the Arizona Department of Public Safety, the Arizona Department of Transportation and the public.

We’ve got a blog post coming up real soon that’s going to focus on Dynamic Message Signs (Don’t know what those are? Keep reading!).

It’s a real shame to see a road tagged with graffiti -- especially because we know all about the effort that goes into building a freeway in the first place.
