US 191: Roadway Realignment Project near Morenci

Freeport-McMoRan Morenci, Ames Construction Company and the Arizona Department of Transportation are working together to realign US 191 from milepost 171 to 172 near Morenci. The 1-mile stretch of the highway is within Freeport-McMoRanMorenci’s open pit mining operation.

Ames will construct a new two-way, two-lane rural highway through this area.

Key elements of the project include:

  • Building a new road base
  • Constructing a tunnel
  • Paving and chip-sealing the roadway
  • Improving drainage through the area

Construction is scheduled to begin in August and last approximately 10 months. The majority of the work is scheduled between August and December 2018, with chip sealing and final striping planned for May and June 2019.

From late August through the end of November 2018, motorists should expect a gravel surface. Motorists are urged to use caution when traveling through the area, particularly during inclement weather, and to obey all temporary traffic signs. Delays of up to 30 minutes are possible.

Once the project is complete, US 191 traffic will flow through a tunnel, and haul trucks will travel over the tunnel, eliminating the current crossing that requires US 191 traffic to yield to haul trucks.
