The Arizona Department of Transportation (ADOT), in cooperation with the City of Phoenix and the Maricopa Association of Governments (MAG), is studying I-10 between the Deck Park Tunnel (near downtown) and the “Split” interchange where I-10 meets I-17 near Sky Harbor Airport. The study also looks at nearby connections like SR 51 and Loop 202 because traffic in this area is all interconnected. See
