The Arizona Department of Transportation completed a study in 2023 that evaluated improvements to the Loop 101 (Agua Fria Freeway) and Interstate 10 system interchange in the West Valley, producing a Design Concept Report.
ADOT has initiated a project to widen and make other improvements to the Loop 202 between Loop 101 and Val Vista Drive in the city of Chandler and town of Gilbert.
The Loop 202 (South Mountain Freeway) adds 22 miles of freeway to the existing Phoenix metropolitan transportation system. The freeway connects the east and west valley while providing much needed relief to existing freeway corridors and local streets.
The Arizona Department of Transportation, in coordination with the Maricopa Association of Governments and the cities of Phoenix and Peoria, is improving Loop 303 between Lake Pleasant Parkway and Interstate 17 by adding an additional general purpose lane in each direction, bridges to accommodate a future interchange at 67th Avenue, and a new Loop 303/I-17 system-to-system interchange. The project seeks to address growing traffic demands on Loop 303.
The Arizona Department of Transportation, in partnership with the Maricopa County Department of Transportation and the Town of Gilbert, is improving Mews Road between Higley Road and 172nd Street.
State Route 30 (Tres Rios Freeway) is a new freeway planned in the southwest valley crossing the cities of Buckeye, Goodyear, Avondale and Phoenix. The center section of SR 30, between Loop 303 and Loop 202, will be constructed first due to its potential to serve as a traffic reliever and alternate route to Interstate 10.
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.
The Arizona Department of Transportation, in coordination with the Maricopa Association of Governments, is starting a pavement rehabilitation project along a 9.5-mile section of State Route 51, between Interstate 10 (Papago Freeway) and Shea Boulevard.
State Route 24 (SR 24), also referred to as the Gateway Freeway, is currently a 5-mile interim roadway between Loop 202 and Ironwood Drive. This section features two lanes in each direction with a center median, bridges over Ellsworth and Mountain roads and at-grade intersections at the following locations:
