This new traffic interchange on Interstate 10 between the existing Avra Valley Road and Cortaro Road interchanges will connect Twin Peaks Road, west of the Santa Cruz River, to Camino de Ma�ana and Linda Vista Boulevard on the east side of I-10. This project will relieve traffic congestion in the Town of Marana and the northwestern area of metropolitan Tucson and provide an infrastructure to aide the growth of northwest Pima County, which continues to exceed the current transportation infrastructure capacity.
