TUCSON, AZ — The Arizona Department of Transportation (ADOT) has kicked off a project to reconstruct and widen Interstate 10 between Kino Parkway and Country Club Road southeast of downtown Tucson.
The $600 million project is the largest highway construction project in southern Arizona history and includes additional lanes on I-10 as well as new interchanges to reduce delays and enhance safety. The project 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 at 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 at 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 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 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.
