State Route 366 repair project begins Jan. 4

December 29, 2020

PHOENIX – Motorists on State Route 366 (Swift Trail) near Safford should expect intermittent delays starting Monday, Jan. 4, to repair damage from the 2017 Frye Fire on Mount Graham.

The work is scheduled for up to two years on SR 366 between mileposts 118 and 140. Key elements of the project include:

  • Removal of burned trees
  • Repairs to the road surface in some locations
  • Drainage repairs
  • Box culvert replacements
  • A chip seal on the paved portion of the highway

While SR 366 will remain open during repairs, drivers should continue to expect standard wintertime closures on the upper, unpaved portion of the highway. 

Most work will occur on weekdays, with some weekend work possible. Drivers should expect delays of up to 30 minutes. The contractor may work on two locations at a time, which could lead to multiple delays for drivers traveling through the area. Signals or flaggers will be used to control traffic.

ADOT is performing the repairs in cooperation with the Federal Highway Administration and the U.S. Forest Service.

Drivers should proceed with caution, slow down and watch for construction personnel and equipment. For more information, go to the project website.
