Loop 202 South Mountain Freeway

South Mountain Freeway

Project Update

On Friday, February 26, 2016, the Arizona Department of Transportation finalized the public-private partnership agreement with Connect 202 Partners to deliver the Loop 202 South Mountain Freeway three years sooner and at a cost savings topping $100 million. The 22-mile freeway, expected to open by late 2019, will provide a long-planned direct link between the East Valley and West Valley and a much-needed alternative to Interstate 10 through downtown Phoenix. For more information, see the official media release.

The Loop 202 freeway, also known as the South Mountain Freeway, will run east and west along Pecos Road and then turn north between 55th and 63rd avenues, connecting with Interstate 10 on each end. A video simulation of the freeway is provided below.

The South Mountain Freeway is the last piece to complete the Loop 202 and Loop 101 freeway system necessary for high-quality regional mobility.

The project has been a critical part of the Maricopa Association of Governments Regional Freeway Program since it was first included in funding through Proposition 300 approved by Maricopa County voters in 1985. The freeway is also part of the Regional Transportation Plan funding passed by Maricopa County voters in 2004 through Proposition 400.

Ongoing Activities

ADOT is currently conducting preliminary engineering activities along the future freeway corridor. Preliminary engineering activities can include soil and rock testing, field investigations and other activities to fulfill the environmental commitments that were made during the study phase of the project.

Additional pre-construction activities include the removal of structures on ADOT-owned properties. ADOT is working very closely with the City of Phoenix on structure removal activity and traffic control, including the posting of work-zone traffic barricades and safety flagmen as necessary. Neighborhood access points will remain open during removal activities. Security personnel will monitor all activity sites throughout this phase of the project to deter any criminal activity.

Please note this visual simulation is a representation of the freeway alignment and conceptual design selected during the study phase of the project. While the alignment of the freeway will remain unchanged, interchanges, elevations and other elements of the freeway may be modified during final design.
