The Maricopa Association of Governments (MAG) completed a corridor study of the Interstate 10 Freeway from the Deck Park Tunnel to the Interstate 10 (I-10)/Interstate 17 (I-17) Interchange (also known as the Split).
The study also included the areas of the I-10/State Route 51/Loop 202 interchange (Mini-Stack) and the north-south portion of I-10 south of the Mini-Stack near Phoenix Sky Harbor International Airport. The study recommended design elements, alternatives, operational strategies, and policy actions to serve as the basis for design and construction of future projects in this corridor.
Several previous studies informed the study, including the I-10/I-17 Corridor Master Plan "Spine Study" and the I-10/Papago Tunnel Traffic Operations Study.
