A three-year, $600 million undertaking to reconstruct and widen a stretch of Interstate 10 will be the largest highway construction project in Southern Arizona history.
In mid-2025, construction will begin on I-10 between Kino Parkway and Country Club Road, wrapping up in 2028, the Arizona Department of Transportation said Friday.
The project will 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.
It will also reconstruct the interchange at Kino Parkway, remove the existing interchange at Palo Verde Road, and construct a new interchange at Country Club Road, providing access for traffic that currently uses the interchange at Palo Verde Road.
A new westbound on-ramp at the Alvernon interchange will be built and an I-10 undercrossing to connect north and south Kino Sports Complex will be constructed.
The project is expected to address traffic congestion in the area, improve safety and increase traffic flow, ADOT said.
It stems from a 2020 study on how to improve mobility along a roughly 10-mile stretch of I-10 from Interstate 19 to Kolb Road, ADOT said.
The study also identified an alignment for an extension of Barraza Aviation Parkway along Alvernon that will connect I-10 to downtown.
The State Transportation Board awarded the design-build project to Sundt-Jacobs. Detailed design plans will be shared, and community members will get to speak with the design team early next year at an open house, ADOT said.
