The saying, “a photo speaks 1,000 words” holds true when it comes to data. Because, for most people (we’re not talking about the engineers who are out there reading this!) it’s hard to pull real meaning from just a long list of numbers.

The official start of winter is approaching, but the cold weather is already here! Over the past few weeks, we’ve told you how ADOT prepares for the snowy conditions common this time of year in Arizona’s high country.

Before you can build a freeway, you’ve got to move a little dirt... Make that a LOT of dirt, especially in the case of the Loop 303 project under construction right now in the West Valley.

ADOT’s Long-Range Transportation Plan was formally adopted earlier this month. ADOT planners will now use the Long-Range Transportation Plan as a guide to build a transportation system designed to carry Arizona into the future! But just who is this group – otherwise known as the State Transportation Board – that adopted the plan?

Snow-covered, icy highways get swift attention from ADOT crews each winter, but some routes face factors so severe, that completely closing the road down for a few months is the best option.

You’d be amazed by how much there is to learn just by counting cars (yes, cars…not cards!)… Traffic counts are exactly what the name implies – physical counts of the traffic on a particular road – and ADOT takes them at approximately 1,400 locations around Arizona.

I-10 was closed most of the day and night last Wednesday after two tanker trucks collided near Chandler Boulevard south of downtown Phoenix. For hours, many drivers could see the resulting column of black smoke. Even more people saw footage and photos of the collision’s aftermath on the news and online.

Last month, as part of our Building a Freeway series, we told you about the massive underground support substructures that help give bridges strength. Next up in the series is an important -- but temporary -- structure that’s used as crews build a bridge, tunnel or even a box culvert.

Driving a snowplow is a lot harder than it looks … Luckily, ADOT has about 395 employees trained and ready to operate the nearly 200 snowplows in Arizona’s fleet.

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.
