ADOT is now offering audio versions of the Weekend Travel Advisory and Roadwork Roundup.

There's a lot of logistics and planning that goes into large products, like the concrete deck pour for the expansion project of I-10 in Casa Grande.

Today's Art of Transportation photo is a meta-level look at our project on I-17 and Pinnacle Peak.

Piers and bridge abutments for the new interchanges at Pinnacle Peak and Happy Valley roads are currently going up, so take a look at some of the work happening right now.

Two slideshows take you through and above projects widening I-10 to three lanes in each direction in Casa Grande and near Eloy.

Drivers can expect to see big things soon on I-17 in north Phoenix.

Before and after photos show how ADOT's Loop 202 South Mountain Freeway project is advancing quickly.

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.

We are just the past the one-year mark for our project to widen I-10 near Eloy. Watch what we have accomplished so far and what drivers can expect before the work finishes later this year.

This effort is interesting beyond the wow factor, as it's a major step forward for a project widening 4 miles of I-10 to three lanes between Earley Road and I-8 in Casa Grande.
