Overview

The Arizona Department of Transportation, in partnership with the City of Scottsdale, widened Loop 101 (Pima Freeway) between Princess Drive/Pima Road and Shea Boulevard by one general-purpose lane in each direction and modified existing interchanges to improve traffic flow on Loop 101 and the cross streets. Construction was completed in early 2026.

Construction on the final surface of the roadway is anticipated to begin in spring 2026. Crews will use the concrete pavement treatment known as diamond grinding and will replace lane striping and other pavement markings.  

What to Expect

  • Work will require lane restrictions and ramp closures and will occur primarily during overnight hours during the week and weekends to minimize traffic impacts. No full closures of Loop 101 are anticipated. 

  • Construction is anticipated to take approximately three months to complete.

  • ADOT will provide advance notice of restrictions and closures to email subscribers and on the project web page.
