I-10

Ina Road has opened over Interstate 10 in Marana, a major step toward completing a modern traffic interchange that is one of the Tucson area’s largest road projects in years.

Take an interactive before-after look at a bridge demolition that's part of a project building a wider I-10 between Eloy and Picacho in central Arizona. 

PHOENIX – The Arizona Department of Transportation and partner agencies are taking an essential step toward widening and other improvements along 23 miles of Interstate 10 between Phoenix and Casa Grande.

In collaboration with the Maricopa Association of Governments and the Gila River Indian Community, where this stretch is located, ADOT has issued a request for proposals for a design concept report and environmental study on adding a lane in each direction and improving existing interchanges.

Both directions of Interstate 10 will be narrowed to one lane overnight in west Phoenix this week for bridge work at the Loop 202 South Mountain Freeway interchange.

Work to create a modern Ina Road interchange with I-10 maintains and improves connections with The Loop, a system of trails and bike routes in the Tucson area.

Meeting March 7 in Tucson

Interchange expected to open in March

Interstate 10: Earley Road to Interstate 8If a picture is worth a thousand words, then slideshows of our I-10 widening projects in Casa Grande and the Eloy area are worth many thousands.

Busy year in southern Arizona

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.

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.

Lane change begins Saturday Dec. 8

The shift comes almost a year to the day since we began clearing and grubbing to make room for a new, wider stretch of I-10, with three lanes in each direction.

Lane switch Dec. 5

Among other things, rest areas are places to stretch legs, walk pets, have picnic lunches and safely use phones and other mobile electronic devices.
