I-10 Backup

Westbound Interstate 10 traffic was backed up for several miles on April 20, 2019, near Sacaton.

PHOENIX — Work on widening Interstate 10 between Casa Grande and Chandler could begin as early as 2023, according to the state’s newest five-year highway construction plan.

According to the Arizona Department of Transportation’s tentative 2021-2025 transportation facilities program posted for public comment Thursday, $50 million is budgeted for the widening project in the 2023 fiscal year.

“The $50 million programmed by ADOT in Fiscal Year 2023 is for the start of construction,” said Laura Douglas, ADOT’s community relations project manager. “The study for this section of I-10 is still ongoing at this point.”

The total budget for the project to widen the 26-mile stretch of freeway from two to three lanes in each direction across the Gila River Indian Community has been set at between $58.25 million and $66 million. More than $8 million has already been allocated for a scoping study and possible design of the project that would encompass construction in both Maricopa and Pinal counties.

Also budgeted for 2023-2024 is the installation of dynamic messaging signs and traffic cameras along the stretch of I-10. Previously approved for 2022 is reconstruction of the Gila River Bridge on the freeway to accommodate the additional lanes at a cost of $13.59 million, which is included in the overall estimate for the widening of the 26-mile stretch.

Another I-10 project in the five-year plan is the rehabilitation of the Red Rock interchange in 2024.

Starting Thursday, ADOT is asking everyone to take a look at the 2021-2025 tentative Five-Year Transportation Facilities Construction Program and send in their thoughts and comments.

The plan is part of the proposed annual update to ADOT’s lineup of all statewide projects. The 2021-2025 Tentative Five-Year Program allocates funding for preservation, modernization and expansion projects.

The complete report, along with an online comment form, can be found at azdot.gov/tentative5year.

You can also email fiveyearconstructionprogram@azdot.gov or call 855-712-8530 with your comments.

The comment period runs until June 2. The State Transportation Board will make its final decision on June 19 about what will be in the updated five-year program.

The program proposes an average of approximately $310 million per year for preservation of bridges and roadways statewide. This moves ADOT closer to its goal of allocating $320 million per year for system preservation.

Preservation projects include repaving highways, filling potholes, extending the life cycle of existing pavement, and repairing or reconstructing bridges. Approximately 67% of all funding allocated to greater Arizona will be directed to preservation projects from FY 2021 to FY 2025.
