State Route 30: Studies

State Route 30: Studies

State Route 30 Corridor Overview

The Maricopa Association of Governments, in partnership with the Arizona Department of Transportation, has been studying a proposed freeway, State Route 30 (SR 30), in the southwest valley that would serve as an alternate route to Interstate 10 crossing the cities of Buckeye, Goodyear, Avondale and Phoenix. The ultimate corridor is planned to connect from State Route 85 (SR 85) on the west to Interstate 17 (I-17) Durango Curve on the east.

Planning for this new freeway corridor is divided into three sections: 

  • West: SR 85 to the future southward extension of Loop 303. This section is not currently funded for design or construction.
  • Center: The future southward extension of Loop 303 to Loop 202 (South Mountain Freeway). This section is partially funded for final design from 97th Avenue to Loop 202 (South Mountain Freeway) and advanced right of way acquisition from the future southward extension of Loop 303 to 97th Avenue. For more information on these projects, please visit the SR 30 Active Projects Page.
  • East: Loop 202 (South Mountain Freeway) to the I-17 Durango Curve. The segment of SR 30 between the future southward extension of Loop 303 from Van Buren Street to MC 85 and Loop 202 (South Mountain Freeway). This section is not currently funded for design or construction.

SR 30 West Section: SR 85 to Loop 303

This segment of SR 30 is not currently funded for design or construction.

SR 30 Center Section: Loop 303 to Loop 202 

This segment of SR 30 is currently funded for advance right of way acquisition and for final design between 97th Avenue and Loop 202. For more information on this project, please visit https://azdot.gov/sr30

SR 30 East Section: Loop 202 to I-17 Durango Curve 

MAG initiated a study to help lay the groundwork for future design, engineering studies, and National Environmental Policy Act (NEPA) documentation with a recommended SR 30 Durango Link corridor. 
The study utilized a two-level screening process, first determining whether potential corridors met the purpose and need identified at the outset of the study, followed by a more detailed review of engineering, environmental, performance and implementation considerations. The ultimate corridor recommendation, shown on the map below, was based on a combination of inputs, including the technical screening process, feedback from the public and stakeholder input. The study identified the south corridor alternative as the preferred alternative.

Construction of this facility is expected to help reduce the duration of traffic congestion on I-10 and I-17, and decrease travel times through and around the study area. The facility would also improve the reliability and redundancy of the transportation system by providing a second major east-to-west transportation facility in the southwestern Phoenix metropolitan area. Funding has been set aside for this facility in MAG’s most recent regional transportation plan, MOMENTUM.
