ADOT Update on $50M Ongoing US 60 Corridor Projects - Superior to Globe

ADOT projects invest in US 60 corridor east of the Phoenix area

Motorists should stay informed about intermittent closures between Superior and Globe

Several projects that are underway or planned during 2016 will significantly upgrade US 60 from Superior to Globe.

In all, the Arizona Department of Transportation has committed nearly $50 million to projects in the corridor, including the addition of a passing lane and wider shoulders as the highway climbs east from  Superior, five miles of new divided highway, rockfall mitigation, bridge work and drainage improvements.

As progress continues, including an upcoming project to replace lighting in the Queen Creek Tunnel, motorists traveling between Superior and Globe should plan ahead and be prepared for intermittent closures.

Two improvement projects are currently underway, and a third will start later this month:

A project started in August 2015 is adding a two-mile westbound passing lane between mileposts 231 and 233, widening the shoulder in Devil’s Canyon (mileposts 233-234), improving a bridge at Waterfall Canyon (milepost 229) and making drainage improvements west of Miami (milepost 242).  Blasting operations for this project have required occasional closures, usually lasting up to 90 minutes, and these are expected to be needed through the end of April with crews more than halfway through excavating 108,000 cubic yards of earth.

ADOT is widening five miles of US 60 just west of and through Superior, a project that when completed in 2017 will convert the last two-lane stretch between Phoenix and Superior to four-lane divided highway. This work will require some traffic restrictions later this year.

This month, ADOT will add LED lighting to improve visibility in the quarter-mile-long Queen Creek Tunnel, which was built in 1952, as well as new conduit and wiring.

In 2015, ADOT completed a rockfall-mitigation project along mileposts 228-229, where crews removed loose boulders along a rocky and steep section of highway adjacent to the Queen Creek Tunnel.

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.
