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


The Arizona Department of Transportation, in partnership with the city of Scottsdale and the Maricopa Association of Governments, has initiated a project to widen the 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 current Loop 101 widening project west of Pima Road/Princess Drive currently under construction, as well as the previous 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.
  • Accommodating future bicycle lanes.

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 soon.  


  • The updated Design Concept Report was released in February 2021.
  • The design phase will begin in 2021.
  • Construction is expected to begin in fiscal year 2023.
