Ultimate Interstate 111
Description Ultimate interstate 111 replaces the planned freeway upgrade for AZ-74 northwest of Phoenix. This freeway would run from south of Wickenburg (planned Hassayampa Freeway) and Lake Pleasant at I-17.
Purpose and Need Connects ultimate intestate 11 route to the norhtside of Phoenix.
Ultimate Interstate 211 - Casa Grande Freeway
Description Ultimate interstate 211 is a planned repurposing of the planned southeastern section of the Hassayampa Freeway. this section would be renumbered as I-211 and I-11 would instead be routed southward along the Gila River wash to Gila Bend and connect directly with I-8 (see map balow). This also facilitates further southward expansion of I-11 southward to the desert regions for additional port of entry crossings than the routing to the southeast at Casa Grande would. This also provides a more simplified bypass for Phoenix using I-8 to I-11 returning to I-10 near Buckeye.
Purpose and Need Simplify interstate planning for central Arizona. Promote continuity with the greater interstate system.
