The Arizona Department of Transportation (ADOT) is preparing to move forward with a project in 2025 that will reconstruct and widen I-10 between Kino Parkway and Country Club Road southeast of downtown Tucson.
On Friday, August 16, the State Transportation Board awarded the $600 million design-build project, which will be the largest highway construction project in southern Arizona history.
The I-10 project will include:
- Widen 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.
- Reconstruct the interchange at Kino Parkway.
- Remove the existing interchange Palo Verde Road.
- Construct a new interchange Country Club Road that will provide access for traffic that currently uses the interchange at Palo Verde Road to allow for safer traffic movements to and from I-10.
- Construct a new westbound on-ramp at the Alvernon Way interchange.
- Construct an I-10 undercrossing to connect the North and South Kino Sports Complex.
Construction is expected to begin in mid-2025 and continue through 2028.
The project will be the first to result from a study completed in 2020 that recommended how to best improve mobility along a roughly 10-mile stretch of I-10 from I-19 to Kolb Road. The study also identified an alignment for an extension of State Route 210 (Barraza Aviation Parkway) along Alvernon Way that will connect I-10 to downtown Tucson.
