US 60 east of Superior to close briefly for blasting operations Sept. 2 and 3 and Sept. 9 and 10

Posted on by

SUPERIOR — Motorists traveling along US 60 between Phoenix and Globe on Wednesday and Thursday mornings, for the next two weeks, need to plan ahead or allow extra time as the Arizona Department of Transportation continues blasting work as part of an improvement project to build a new passing lane and widen roadway shoulders east of Superior, approximately 65 miles east of downtown Phoenix. The closures are scheduled for Sept. 2 and 3 and the following week for Sept. 9 and 10.

The construction of the two-mile-long climbing lane from Devil’s Canyon to Oak Flat (mileposts 231-233) will require a full closure of US 60 for up to 90 minutes from 9 a.m. to 10:30 a.m. on Sept. 2 and 3.

Traffic on eastbound US 60 will be stopped east of Superior (milepost 227) and westbound US 60 will be stopped at the Top of the World, west of Miami (milepost 235) until the blasting work is completed and the roadway is reopened after all debris is cleared. Law enforcement officers will be stationed at each closure to assist with traffic control.

ADOT anticipates the highway will be closed at least once per week for blasting for up to three months. As blasting continues there will be a lesser impact on traffic and delays will be reduced.

Motorists seeking an alternate route can consider state routes 77 and 177, which is approximately 68 miles long.

The $8.8 million safety improvement project will make it easier for motorists to pass large trucks and slow-moving vehicles whose speed drops because of the sustained grades along this stretch of highway from Devil’s Canyon to the Oak Flat area.

The project will include the following:

  • Construction of a new westbound passing lane from Devil’s Canyon to Oak Flat (mileposts 231-233)
  • Widening shoulders in the Devil’s Canyon area (milepost 233-234)
  • Improvements to the Waterfall Canyon bridge (milepost 229)
  • Box culvert drainage improvements (milepost 242 just west of Miami)

ADOT will work to minimize the traffic impacts as much as possible, including scheduling some nighttime work.

There will be narrow traffic lanes, wide-load restrictions and a reduced speed limit through the work zone. Flaggers and pilot cars will be used at different times throughout the project.

Drivers are asked to use caution, watch for construction equipment and personnel, and allow extra time for your commute.
