Loop 101 (Pima Freeway), Princess Drive to Shea Boulevard Improvements


The Arizona Department of Transportation, in partnership with the city of Scottsdale, the Federal Highway Administration and the Maricopa Association of Governments, has initiated a project to widen Loop 101 (Pima Freeway) between Princess Drive and Shea Boulevard and modify existing interchanges to improve traffic flow on Loop 101 and the cross streets.


A Design Concept Report (DCR) and environmental study was completed in 2010, which recommended the addition of a general-purpose lane in each direction and interchange improvements. The DCR was updated in 2021 to re-evaluate the interchanges to better accommodate increased traffic volumes in this area.

Planned Project Elements

  • Widening Loop 101 to add one general-purpose lane in both the northbound and southbound directions between Princess Drive and Shea Boulevard. This project will tie into the Loop 101 widening project from I-17 to Pima Road/Princess Drive, completed in 2022, and the earlier Loop 101 widening project south of Shea Boulevard.
  • Reconstructing the interchange at Frank Lloyd Wright Boulevard to a new configuration.
  • Making minor modifications to the interchanges and cross-streets at Princess Drive, Raintree Drive and Shea Boulevard to improve turning movements.
  • Reconstructing sidewalks to comply with current Americans with Disabilities Act (ADA) standards.

Public Input

The public was surveyed in 2020 to gather input on the proposed interchange concepts. A summary of the survey results will be available in the near future. 


  • The updated Design Concept Report was released in February 2021.
  • Project is currently in the design phase.
  • A Virtual Public Meeting was held on Wednesday, Nov. 2, 2022.
  • Project construction is anticipated to begin in the fall of 2023.
  • It's expected to take approximately two years to complete.
