ADOT Blog

ADOT will be testing out its Dynamic Message Signs by posting “EMERGENCY ALERT SYSTEM TEST IN PROGRESS” from 11:30 a.m. to 12:30 p.m. Dynamic Message Signs are an important tool and are already used by ADOT to get the word out on AMBER Alerts and other critical information.

You might say each ADOT road construction project is a sum of its parts

When a new highway operation technician is hired by ADOT, they’ve got one year to complete some basic training …

We started this blog back in April with a definite vision in mind… Informing readers about ADOT projects, programs and services was certainly our aim, but we also wanted to give some insight on why and how we do things around here and maybe even highlight some cool facts about our state’s transportation system.

Arizona drivers now have even more designs to consider… four new specialty plates (Arizona Centennial, Boy Scouts of Arizona, Hunger Relief and Channel 8 PBS) are available starting today!

If you haven't yet heard, last Friday night WSDOT closed the Alaskan Way viaduct -- one of the two main north-south freeways through downtown Seattle -- for demolition and ultimate replacement with a waterfront tunnel.

The ADOT Research Center Library might not carry any best-sellers, but where else are you going to find a title like, “Benefits of high volume fly ash: new concrete mixtures provide financial, environmental and performance gains”?

You know when you drive under or over a freeway bridge that it’s a massive structure… There are the two abutments (the upright supporting structures at each end that carries the load of the bridge span), there are usually center columns or piers, and, of course, the girders and the bridge deck (the part you actually drive across).

They're typically headed to one of the country’s biggest tourist destinations -- the Grand Canyon. One of the main routes to the popular south entrance happens to be State Route 64, which takes motorists right through the middle of Tusayan (pop. 560). The small town gets a lot of pedestrian and vehicle traffic and understandably there have been some concern related to all the activity on SR 64.

Earlier we told you about the new intercity rail study that’s going to help ADOT examine the possibility of a new transportation link between Phoenix and Tucson. (By the way, there’s still plenty of time to comment and we hope you will!) But, today, we really want to focus on why ADOT conducts studies like this one.
