An uncommon structure over a roadway.
We have another "Where in AZ??" challenge that is sure to stump some of you but be easy for others.
Aerial view of the US 93
We've already widened 161 miles of US 93, the main route between Phoenix and Las Vegas, to divided four-lane highway. Now we're launching a project to widen nearly 4 more miles.
Roadway leading into a storm front
After an extended stretch of dry weather, Arizona drivers should prepare for driving in the rain – or in snow at higher elevations – late this week and into the weekend.
Hands on a steering wheel - Focus on Driving.com
We are launching a website with a collection of safe-driving resources to help drivers make better decisions behind the wheel.
Aerial view of the South Mountain Freeway overpass deck pour
This week's Art of Transportation is all about giving some scale to what goes into a major undertaking such as the South Mountain Freeway.
South Mountain Freeway Overpass construction
Before and after photos show how ADOT's Loop 202 South Mountain Freeway project is advancing quickly.
Small town main street
Showcase your knowledge with our Sunday "Where in AZ??" challenge!
Demolition of the old Jimmie Kerr Bridge
Watch as our drone flies over the demolition work on the old I-10 bridges at Jimmie Kerr Boulevard in Casa Grande and the new bridges that are part of a widening project there.
Salt River Bridge
Whether today or 40 years ago, our highway engineers and crews are thinking about how to move traffic from one side to the other of the Salt River in Phoenix.
Preparing to pour concrete deck over rebar.
A deck pour is a lot more than simply laying steel and pouring cement. It can be beautiful too.
Recycling old freeway material.
Recycling is for more than just old newspapers and soda cans. In Pinal County, ADOT is saving time and money as we widen I-10 near Eloy by recycling old highway lanes.
Dirt road
Some take the road less traveled. This week's "Where in AZ??" location definitely falls in this category.
