Loop 101 Widening Study: Interstate 17 to Pima Road

The Arizona Department of Transportation (ADOT), in cooperation with the Federal Highway Administration (FHWA), initiated a Design Concept Report (DCR) and environmental study to evaluate the addition of one general-purpose travel lane in each direction on a 13-mile stretch of Loop 101 (Pima Freeway) from I-17 to Princess Drive.

Growing traffic demand has caused the Loop 101 corridor to become increasingly congested during the morning and evening peak travel periods, and traffic volume projections indicate the congestion will worsen in the future. This study evaluated the addition of general-purpose travel lanes to increase freeway capacity and help alleviate increased levels of traffic congestion in the future.

The study evaluated numerous alternatives and potential impacts of providing the additional travel lanes, and the DCR includes a preliminary design concept for the recommended improvements. Potential environmental impacts will be documented in an environmental document following the requirements of the National Environmental Policy Act (NEPA). This study is a component of the Maricopa Association of Governments' Regional Transportation Plan Freeway Program. Multiple design alternatives were evaluated and considered for this study.

Recommended Improvements

The public was encouraged to provide study-related comments and questions to be considered by the project team and addressed in the DCR and draft environmental document. These are the recommended improvements:

  • Adding two general-purpose lanes in the eastbound direction between the I-17 and Seventh Avenue
  • Adding one general-purpose lane in the eastbound direction between Seventh Avenue and State Route 51 (SR 51)
  • Adding one general-purpose lane in the eastbound direction between Tatum Boulevard and Princess Drive
  • Adding two general-purpose lanes in the westbound direction between I-17 and Seventh Avenue
  • Adding one general-purpose lane in the westbound direction between Seventh Avenue and SR 51
  • Adding one general-purpose lane in the westbound direction between SR 51 and Princess Drive
  • Adding auxiliary lanes in each direction between Seventh Street and Cave Creek Road

Additional alternatives may be considered based on study-related comments and questions received.

Comments on the widening project were received in early 2015, and were submitted either by attending one of the three public information meetings listed below or by one of these methods:
