The Arizona Department of Transportation (ADOT) began a $600 million project that will widen Interstate 10 between Kino Parkway and Country Club Road, kvoa.com reported.
The project is the largest highway construction initiative in southern Arizona's history.
The State Transportation Board awarded the design-build project to Sundt-Jacobs.
The project is designed to improve traffic flow and safety by adding lanes and constructing new interchanges, according to kvoa.com.
That includes expanding I-10 into three lanes in each direction between Kino Parkway and Alvernon Way. It also includes the reconstruction of the Kino Parkway interchange, construction of an I-10 undercrossing that connects the North and South Kino Sports Complex, and the construction of a new interchange at Country Club Road.
In addition, the existing Palo Verde Road interchange will be removed, while a new westbound on-ramp at Alvernon Way will be built, according to kvoa.com
This project will follow the 2020 Interstate 10 and State Route 210 Transportation Design Concept Report (DCR) that recommended improvements for a 10-mile stretch of I-10 to Kolb Road. That included extending State Route 210 along Alvernon Way to connect I-10 to downtown Tucson.
The I-10: Kino to Country Club project was programmed into the 2024-2028 Five-Year Transportation Facilities Construction Program as a Design/Build in FY 25.
Construction is expected to be completed by summer 2028.
