South Central Projects

State Route 86 from Valencia Road to Kinney Road Widening Project

The Arizona Department of Transportation, in conjunction with Pima County and the Federal Highway Administration, is currently in the design phase of a project to widen a segment of SR 86 (Ajo Highway) between Valencia and Kinney roads. The purpose of the project is to enhance safety and improve traffic flow along this segment of SR 86 in Tucson and to meet current and future traffic needs.

This segment of SR 86 experiences a steady volume in commuter traffic because of ongoing residential development in the area and existing employment destinations in Tucson.

Additionally, SR 86 serves as a regional transportation route between Tucson and south-central Arizona and provides access to the Tohono O'odham Nation. The state route also is used to reach the popular tourist destination of Puerto Peñasco in Sonora, Mexico, also known as Rocky Point.

The SR 86 Valencia Road to Kinney Road project's design phase began in October 2011 and is expected to last approximately 18 months. The new design will be consistent with the Final Design Concept Report and Environmental Assessment, which was finalized in the summer of 2010. Proposed construction is expected to begin in fall 2014.

These are the proposed improvements of the project:

  • Widening the roadway to two lanes in each direction
  • Creating four travel lanes from Valencia Road to Sheridan Avenue
  • Creating six travel lanes from Sheridan Avenue to Kinney Road

The design will include traffic control enhancements, utility relocation, drainage features, improved connections with local access streets and low-maintenance landscape.

The project includes six signalized intersections, two bridge structures and several major drainage structures.
