Jacobs Designing Southern Arizona’s Largest Highway Construction Project

Jacobs is designing southern Arizona’s largest highway construction project in a design-build partnership with Sundt Construction. The Arizona Department of Transportation’s Kino to Country Club project aims to improve traffic flow and safety on Interstate 10 (I-10), creating a critical link between major highways and local roads. 

This $600 million investment will expand a three-mile stretch of I-10 in both directions and reconstruct and remove existing interchanges to ease congestion. Our design team will develop the final design for all the structures and roadways and provide engineering documents for construction. 

“The Kino to Country Club Road program is a pioneering effort and will bring best practices in alternative program delivery to Arizona,” says Jacobs Transportation Market Growth Director – West Central Galina Leiphart. “Working with the Arizona Department of Transportation and Sundt as our design-build partner, we’ll deliver a safer, more efficient transportation system that supports growth and connectivity across Arizona and improves traffic flow and safety in the local Tucson community.” 

Construction began in June 2025 and is anticipated to continue through 2028.
