Having already cleared nearly 90,000 cubic yards of rock material from a mountainside, the Arizona Department of Transportation is entering its final stages of blasting work needed to build a passing lane and widen roadway shoulders east of Superior.

After having no travel restrictions this week, US 60 blasting operations will resume on Tuesday, March 1, and Thursday, March 3, and continue on a twice-weekly schedule until the end of the project in late April.

During that period, the closures for work between Devil’s Canyon and Oak Flat (mileposts 231-233) will be every Tuesday and Thursday from 9 a.m. to 1 p.m. Motorists should plan ahead and consider alternate routes.

Traffic on eastbound US 60 will be stopped east of Superior (milepost 227), and traffic on westbound US 60 will be stopped at the Top of the World, west of Miami (milepost 235), until the blasting work is completed and debris is cleared.

Blasting operations are expected to be completed by the end of April. ADOT needs to excavate an additional 40,000-50,000 cubic yards of earth. Following the blasting work, ADOT will pave the widened roadway before opening the additional travel lane to traffic this summer.

ADOT started the $8.8 million project in August 2015 to provide the westbound passing lane, shoulder widening in Devil’s Canyon (mileposts 233-234), bridge work at Waterfall Canyon (milepost 229) and drainage improvements (milepost 242) west of Miami.

Approximately 30 minutes prior to each blast, motorists should be prepared for possible delays and lane closures as crews set concrete barrier prior to each scheduled closure.

Motorists seeking an alternate route can consider state routes 77 and 177, which is approximately 68 miles long. Motorists headed to the White Mountains region, including Show Low and Springerville, can take State Route 87 through Payson and travel east on State Route 260.

Drivers should use caution, watch for construction equipment and personnel, and allow extra time.
