The opening of the Twin Peaks interchange marks the completion of an $84 million project more than 20 years in the making. The project was constructed to help relieve traffic congestion in the Town of Marana and the northwestern area of metropolitan Tucson. The new Twin Peaks Interchange is located on Interstate 10 (I-10) at exit 245 between the Avra Valley Road and Cortaro Road interchanges. Terracon provided full-time construction materials quality control and Special Inspection services for the project.
