U.S. Route 60: Oak Flat to Miami East

US 60 Closures for Blasting
through the summer, closures are planned weekly on Tuesdays and Thursdays from 9 a.m. to 1 p.m. each day.

The Arizona Department of Transportation started the US 60 project, Oak Flat to Miami, June 17, 2015. The project is anticipated to be completed in summer 2016.

This project involves constructing a westbound passing lane from Devils Canyon to Oak Flat (approximately five miles east of Superior), shoulder widening in Devils Canyon, bridge work at Waterfall Canyon (located just east of the Queen Creek Tunnel) and some drainage improvement just west of Miami.  The passing lane and shoulder widening portion of this project will require the closure of US 60 for blasting.

Prior to each blast, there will be short delays as flaggers route traffic around crews who are placing concrete barrier at the blasting locations. The barrier is needed to control the debris from the blasts.

Steep, rugged terrain and high winds have added challenges for crews working to create room for an additional lane on US 60 between Globe and Superior. Because of that, the project will continue through the summer, including twice-weekly closures for blasting work.

Crews have about 25,000 cubic yards of rocks and dirt – about 2,000 truckloads – to remove to complete the project between mileposts 227 east of Superior to milepost 235 west of Miami.  In addition to creating a passing lane, the Arizona Department of Transportation project is widening the shoulders in Devil’s Canyon (mileposts 233-234), making improvements to the bridge at Waterfall Canyon (milepost 229) and improving drainage (milepost 242) west of Miami.

Drivers who rely on US 60 should continue to plan ahead for closures from 9 a.m. to 1 p.m. on Tuesdays and Thursdays.

After crews blast away rock in one area to make room for the climbing lane, they must maneuver heavy equipment up steep, narrow roads to prepare for the next blast. This spring, two periods of “red flag” conditions – high winds and low humidity that increase the danger of sparking a fire – have delayed work for about two weeks.

During the closures, drivers should consider taking state routes 77 and 177 between Superior and Globe, a route of about 68 miles. 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.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule. To stay up to date with the latest highway conditions around the state, visit the ADOT Traveler Information System at or call 511.

This page will be updated with the latest information on the project as it becomes available. Variable message boards will be posted on US 60 around the construction area to inform motorists about project.
