I-10 Overhaul Set to Transform Tucson | Tucson News

Arizona’s biggest highway upgrade is hitting the road—$60 million, three miles of I-10 southeast of Tucson are being rebuilt with new lanes, bridges, and a groundbreaking diverging diamond interchange at Country Club Road. Starting Friday, August 14, the Palo Verde interchange shuts down for demolition and construction, paving the way for smoother traffic and safer travel. This massive project, launched in June 2025 and set to finish by 2028, marks the first major step since a 2020 mobility study—and could eventually connect downtown Tucson to I-10. Drivers brace for change as crews lay pavement, tear down old structures, and build the future of Southern Arizona’s busiest corridor.
