Loop 101 (Pima Freeway) Improvement Project: Interstate 17 to Pima Road

In 2019, the Arizona Department of Transportation initiated a project to widen and improve the Loop 101 (Pima Freeway) from Interstate 17 in Phoenix east to Pima Road in Scottsdale. Improvements were needed to address growing traffic congestion on Loop 101, especially during the morning and evening peak travel periods.

Major elements of the project included:

  • Adding one general purpose lane in each direction between I-17 and Pima Road
  • Adding an auxiliary lane in each direction between Seventh Street and Cave Creek Road
  • Constructing a new overpass structure at the future Miller Road alignment in Scottsdale
  • Modifying freeway ramps and frontage road connections at 11 interchanges
  • Additional components included construction of noise or retaining walls where warranted, improvements to drainage and diamond grinding of the concrete pavement.

The project was completed in early spring 2022.
