I-10/Palo Verde interchange in Tucson to permanently close Aug. 14

Closure needed as part of project to reconstruct, widen I-10 from Kino to Alvernon Way

TUCSON - The Arizona Department of Transportation will permanently close the Interstate 10 interchange at Palo Verde Road the night of Friday, Aug. 14, as part of an ongoing project to reconstruct and widen I-10 from Kino Parkway to Alvernon Way.

The closure is set for 9 p.m. Aug. 14. The upcoming change is the latest sign of progress on ADOT's $600 million project to modernize approximately 3 miles of I-10 southeast of downtown Tucson by adding travel lanes and improving interchanges.

The Palo Verde interchange closure will allow crews to further reconstruct the highway after demolishing the existing bridges at Palo Verde and Irvington roads, along with demolishing the existing travel lanes on I-10.

The closure sets the stage for another nearby change. Just west of the Palo Verde interchange, ADOT will open a new interchange at Country Club Road this fall. That interchange is taking shape, with much of the paving complete for the new roadway and ramps.

The I-10 project began in June 2025 with the goal of reducing delays and enhancing safety. Major project features include adding a third lane in each direction of I-10 and building two interchanges.

The project, considered the the largest highway construction project in Southern Arizona history, will include:

• Widen I-10 to three lanes in each direction between Kino Parkway and Alvernon Way with auxiliary lanes
• Reconstruct the interchange at Kino Parkway
• 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

Throughout the project, ADOT will maintain two lanes of travel in each direction on I-10 during peak travel times while maintaining access to businesses. Construction is expected to continue through 2028.

The project is the first to result from the I-10/SR 210 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.
