US 70 Passing Lane project near Peridot

The Arizona Department of Transportation has begun a project to add a passing lane along about 1 mile of US 70 near Peridot.  Work is taking place just west of the San Carlos High School between milepost 268 and milepost 269.

Drivers should plan for lane restrictions from June through October 2018.  Motorists can expect shoulder closures, single-lane travel, and flagger stations with possible pilot car operations.

The project includes the following elements:

  • Widening the existing roadway
  • Milling and repaving the existing travel lanes
  • Extending several pipes and box culverts

Work is scheduled to take place between approximately 5 a.m. and 3 p.m. weekdays. The speed limit within the work zone will be reduced from 55 mph to 35 mph.

Drivers and pedestrians should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
