Drivers will begin driving on a newly constructed section of Interstate 10 this weekend.
Traffic will be shifted onto more than a mile of new concrete pavement from Park Avenue to Country Club Road.
This marks a major milestone in a $600 million project to reconstruct and widen I-10 from Kino Parkway to Alvernon Way.
ADOT says the project is now 40% complete.
Along with the traffic shift, ADOT wants drivers to be aware of other changes in the work zone.
- The westbound I-10 off-ramp to Park Avenue will close for up to 90 days.
- The eastbound I-10 on-ramp at Park Avenue will close for up to 90 days.
- The westbound I-10 on-ramp at Palo Verde Road will close permanently.
Work began in June 2025 with the goals of reducing delays and enhancing safety. Major project features include adding a third lane in each direction of I-10 and building two interchanges.

Considered the largest highway construction project in southern Arizona history, this improvement will:
- 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
- Remove the existing interchange Palo Verde Road
- 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 says it 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.
