TUCSON – The Arizona Department of Transportation (ADOT) is set to begin a major reconstruction and widening project on Interstate 10 between Kino Parkway and Country Club Road, southeast of downtown Tucson.

On Friday, the State Transportation Board awarded a $600 million design-build contract to Sundt Construction, Inc., to enhance mobility and safety along this stretch of I-10, according to ADOT.

Slated to begin in mid-2025, the project will be "the largest highway construction endeavor in southern Arizona's history," ADOT said.

The project will include the following key elements:

• Widening I-10 to three lanes in each direction between Kino Parkway and Alvernon Way, and to four lanes in each direction west of Kino Parkway.
• Reconstructing the interchange at Kino Parkway.
• Removing the existing interchange at Palo Verde Road.
• Constructing a new interchange at Country Club Road to provide safer access to and from I-10, replacing the Palo Verde Road interchange.
• Building a new westbound on-ramp at the Alvernon Way interchange.
• Constructing an I-10 undercrossing to connect the North and South Kino Sports Complex.

The design-build project is the first to emerge from a 2020 study that recommended improvements for a 10-mile stretch of Interstate 10 from Interstate 19 to Kolb Road.

The study also identified an alignment for extending State Route 210 (Barraza Aviation Parkway) along Alvernon Way, which will connect I-10 to downtown Tucson, according to the Arizona Department of Transportation (ADOT).

ADOT plans to present detailed design plans and offer an opportunity for public input at a community open house in early 2025.
