  • Drivers should expect a single lane of traffic where crews are working. Flaggers will guide motorists through the work zone.
  • Expect delays of up to 15 minutes during daylight hours.


The project will be completed in the summer and early fall of 2020.


SR 86 serves as a recreational and commercial route between Tucson and southwestern Arizona, carrying a high percentage of trucks and recreational vehicles. SR 86 provides access to the Tohono O’odham Nation and is widely used to reach popular destinations such as Organ Pipe National Monument and Puerto Peñasco, Mexico (also known as Rocky Point).
