Project Overview
The Arizona Department of Transportation (ADOT) is studying long-term improvements for 41 miles of Interstate 10 (I-10), between Interstate 8 (I-8) at milepost 199 in Casa Grande and Tangerine Road at milepost 240 in Marana.
The goal of the study is to establish a plan to guide the development of I-10 through the year 2030.
What the Study will Evaluate
• Highway deficiencies
• Freight mobility
• Frontage roads
• Traffic interchanges
• Drainage features
• Environmental issues
Project Schedule and Purpose
• Began in the spring of 2006
• Complete in the spring of 2008
• Will produce an Access Management Plan and Design Concept Report
• Will follow the National Environmental Policy Act process to evaluate alternatives for improvements and document potential impacts to the social, natural and cultural environment
• Will identify and incorporate environmental mitigation measures into future I-10 improvements

ADOT is planning to move forward with four additional widening projects along I-10 to expand the freeway to three lanes in each direction as follows:
Typical section of Interstate 8 to State Route (SR) 87: construction could begin in 2008
Typical section of SR 87 to Picacho Peak Road: construction could begin in 2008
Typical section of Picacho Peak Road to Pinal Air Park: construction to begin in winter 2007/2008
Typical section of Pinal Air Park to Tangerine Road: under construction
Please see Fact Sheets for more information regarding the Picacho Peak Road to Pinal Air Park section.
