ADOT Blog

We’re just one day away from a very significant date in our state’s history … tomorrow is when Arizona officially celebrates 100 years of statehood! We don’t know about you, but such an important milestone really starts to make us think about what life must have been like for Arizonans way back in 1912.

When we blogged about quiet pavement back in December, we got a lot of comments… We received plenty of questions, too, which we’ll attempt to answer here on the blog in the coming weeks – starting with one on bridge expansion joints.

We asked and you answered! Back in December when we told you about the Quiet Pavement Pilot Program, we launched a survey asking for your thoughts on freeway surface conditions in Maricopa County.

Nothing seems to slow a commute down like having to stop at one red light after another. That’s why ADOT is working to synchronize some of its signals – a move that can help traffic flow a little more smoothly while reducing the type of stop-and-go traffic that can lead to congestion.

There's a lot of useful information to be obtained from our roadways and loops help ADOT collect some of that data.

Last week we received a blog comment requesting an update on the I-17 bridges that span over Pinewood Boulevard in Munds Park. We thought it was a great suggestion and figured a blog post was in order!

Yesterday we told you about ADOT’s Pavement Materials Testing group and how it is responsible for testing aggregate and creating asphalt friction course mix designs.

Placing asphalt friction course on a newly constructed road is sort of like icing a cake (stay with us here).

Remember this awesome time-lapse video showing the construction of a temporary bypass at Greenway Road and the Loop 303? Well, today we’ve got an even more in-depth look at how crews built the new intersection – complete with temporary barriers, fences and traffic signals – in just about 43 hours! (Take a look at the photos below for an amazing before and after aerial glimpse of the new bypass!)

When ADOT builds a freeway, there is an essential step that surprisingly requires absolutely no construction or even heavy lifting. We’re talking about partnering – the ADOT and construction industry process that allows everyone on the project to get together, set goals and talk about the work ahead.
