ADOT will close the interchange at 9 p.m. Friday as part of a $600 million project to rebuild and widen I-10 from Kino Parkway to Alvernon Way.
The Arizona Department of Transportation (ADOT) will permanently close the Interstate 10 interchange at Palo Verde Road at 9 p.m. on Friday, Aug. 14, as part of an ongoing project to reconstruct and widen I-10 from Kino Parkway to Alvernon Way.
The closure will allow crews to demolish the existing bridges at Palo Verde and Irvington roads and continue rebuilding the highway. This is the latest step in ADOT’s $600 million project, which is the largest highway construction effort in Southern Arizona history.
What Drivers Need to Know
After the closure, motorists who currently use the Palo Verde interchange will need to use alternate routes. A new interchange at Country Club Road is expected to open this fall, providing access for traffic that previously used Palo Verde. Until then, ADOT advises drivers to plan ahead and use nearby interchanges such as Kino Parkway or Alvernon Way.
Throughout the project, ADOT will maintain two lanes of travel in each direction on I-10 during peak travel times, and access to businesses will be preserved.
Project Details
The I-10 project began in June 2025 and includes:
- Widening I-10 to three lanes in each direction between Kino Parkway and Alvernon Way, with auxiliary lanes
- Reconstructing the interchange at Kino Parkway
- Building a new interchange at Country Club Road
- Constructing a new westbound on-ramp at the Alvernon Way interchange
- Building an I-10 undercrossing to connect the North and South Kino Sports Complex
Construction is expected to continue through 2028. The project aims to reduce delays and enhance safety along this roughly 3-mile stretch of I-10 southeast of downtown Tucson.
The project is the first to result from a study completed in 2020 that recommended improvements for a 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.
