PHOENIX – The upper, unpaved portion of State Route 366, which ascends Mount Graham into the Pinaleño Mountains southwest of Safford, reopened Friday, April 24, for the spring, according to the Arizona Department of Transportation.

SR 366, also known as the Swift Trail, begins about 5 miles south of Safford off of US 191.

Before heading off to enjoy the mountains, motorists should do the following:

  • Make sure all occupants in a vehicle are buckled in.
  • Check tire pressure, fluids and more to make sure a vehicle is in proper running condition.
  • Be patient, including not following other vehicles too closely and building in extra travel time.
  • Get enough sleep before the trip.
  • Bring extra water and food.
  • Never drink and drive.
