Arizona isn’t known for its harsh, winter weather conditions, but that doesn’t mean we don’t see some considerable snowfall during our colder months.

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 …

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.

Construction got started earlier this fall on a project that’s designed to bring some big improvements for a stretch of Interstate-10 in the Tucson area. The I-10 widening project from Ruthrauff Road to Prince Road will not only expand the freeway to four lanes in each direction, but will also reconstruct the Prince Road traffic interchange so the road will pass over the Union Pacific Railroad tracks and I-10. New landscaping and entrance and exit ramp improvements are also part of the plan.

Several miles of new HOV lanes opened earlier this week in Chandler and the West Valley … just in time for the Monday morning commute!
