Red means stop and green means go, but what about a flashing yellow arrow? It’s a traffic signal you might not encounter daily, however ADOT plans on adding one to the I-10 interchange at 32nd Street near Phoenix Sky Harbor International Airport and drivers should be prepared for the change.

What’s filled with sand, weighs up to 1,400 pounds and is designed to save lives? If you answered a sand barrel crash cushion, you’re correct! And, if you didn’t have a guess then you’re probably asking: What’s a sand barrel crash cushion?

Hard to believe, but just two months ago it was still technically winter… Since then, temperatures around the state have warmed up and we're officially headed toward summer. Besides the hotter temps, this time of year also brings about the reopening of roads, routes and highways closed by ADOT for the winter.

Late last week a travel alert went out to warn drivers of some heavy smoke present near SR 69 due to the Gladiator Fire burning near Crown King.

A three-day weekend is coming up and that means a lot of people will be hitting the road… It’s the perfect time to take a road trip, but it’s also wildfire season and we’ve all got to be a bit more careful in this dry, desert climate we live.

Next time you’re at a party and really want to impress the crowd, try throwing out this bit of transportation trivia: more than 1.3 million new Arizona license plates were produced last fiscal year. That’s a lot of plates!

If you’ve ever driven between Arizona and Las Vegas, you’re probably pretty familiar with US 93. It’s the stretch of road traveled by countless motorists each day and it is in the midst of a major update.

This is a blog post about the 2012 award for Airport of the Year – an honor presented annually to an airport that accomplishes much in the areas of community relations, airport management, maintenance activities and innovative programs.

Pedestrian hybrid beacons have been deployed across the nation, including the Phoenix and Tucson metro areas, to improve safety for pedestrians.

At ADOT we always want to give drivers a warning of what’s coming up on the road ahead... Whether it’s an impending freeway closure or a new type of traffic signal, we try our very best to get the word out ahead of time so motorists know what to expect. But, sometimes something will impact our roads (and the ability to drive them) quickly and without much notice, making it all the more difficult to get the message out.

Our mission this week is massive and we’ve got to admit, we are going to need a little help. We’re trying to spread the word on monsoon and dust storm safety and we want to reach as many people as possible, which is where you come in!

Since yesterday we’ve received a number of really inspired Haboob Haikus. We are overwhelmed by the creativity that’s out there! Have you had the chance to submit a poem yet?

We've been pretty entrenched in social media this week so we thought we'd take this opportunity to answer a question we get asked from time to time... Why, as a state agency, does ADOT commit resources to social media?

We're headed into monsoon season (the official start is today) and those dusty, unpredictable storms are on their way...

Would you say that you’re a planner, or do you adhere to more of a “let’s see what happens” approach to life? Nothing wrong with either attitude, but here at ADOT we’re definitely planners (no surprise – we’ve blogged plenty about it!).

Placing Portland Cement Concrete Pavement (PCCP) is one of the final steps involved when building a road, but it’s far from an afterthought…

When Haboob Haikus made the news all the way in New Zealand, we started to realize this Twitter challenge of ours was really taking off! Who could have guessed that #HaboobHaiku would end up yielding more than 500 stories in worldwide media outlets?

Transportation funding is an extensive topic and even though we’ve covered it in the past, there’s still more to blog about. So, today we’re focusing on a particular funding source available for really big transportation projects – ones that, when completed, will have a significant national or regional impact.

You probably don’t think much about drainage when you’re driving, but a well-designed drainage system can increase the lifespan of a highway and help keep the public safe. We’ll blog about how these systems are designed and maintained soon, but today we just want to give you a quick glimpse of the types of drainage solutions used on a project like the Loop 303/I-10 interchange.
