State Route 86: Shoulder Widening near Sells

The Arizona Department of Transportation and Federal Highway Administration are completing a project to widen the shoulders on State Route 86 east of Sells between mileposts 120 and 124 on the Tohono O’odham Nation. In addition to widening the shoulders, the project includes a bridge replacement and culvert extensions.

Traffic Impacts

  • Drivers should expect a single lane of traffic where crews are working. Flaggers and pilot cars will guide motorists through the work zone.
  • Expect delays of up to 15 minutes.
  • During the bridge reconstruction phase, drivers will use a short bypass route.


Work began in September 2019 and will extend through late 2020.
