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

Project Overview

The Arizona Department of Transportation has initiated a project to widen and improve the Loop 101 (Pima Freeway) from Interstate 17 in Phoenix east to Pima Road in Scottsdale. Improvements are needed to address growing traffic demands in the northeast Valley and relieve traffic congestion on the Loop 101 during the morning and evening peak travel periods.

Major elements of this project include:

  • 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
  • Modifying freeway ramps and frontage road connections at 10 interchanges  

Additional components include construction of noise or retaining walls where warranted, improvements to drainage and new rubberized asphalt resurfacing and pavement markings.

This project is utilizing the design-build (D/B) method of delivery to help reduce the overall project timeline. This delivery method differs from the more traditional design-bid-build approach in which the project is completed in two phases (designed and then constructed).

The D/B method involves pairing civil engineering firms with construction contractors to create “design builders” who work synergistically from beginning to end. This creates more opportunities for innovation and can reduce costs. The D/B method of delivery is most advantageous when transportation improvements are needed immediately to reduce high traffic volume or chronic congestion. Learn more about the D/B project delivery method.

Future Related Projects

Study and design of a similar widening project is planned on Loop 101 (Pima Freeway) from Pima Road to Shea Boulevard in Scottsdale. Construction is currently programmed for late 2020/early 2021.

Public Outreach

ADOT is scheduled to host two public meetings in Phoenix and Scottsdale in late 2018 or early 2019 prior to the start of construction. Dates, time and locations of meetings will be announced in advance.
