State Route 30 (Tres Rios Freeway) is a new freeway planned in the southwest valley crossing the cities of Buckeye, Goodyear, Avondale and Phoenix.

Design is currently underway for the SR 347: I-10 to the City of Maricopa Roadway Improvements Project. There are four main elements of this major corridor improvement project, which is located along SR 347 between Interstate 10 and the City of Maricopa.
