Future improvement projects along US 60 near Globe to cause delays

Blog-2015-0515-US60_ Click for larger view. Attention motorists who travel regularly on US 60 between Globe and Phoenix: a series of upcoming improvement projects will impact traffic on the highway this summer...

ADOT  is investing nearly $65 million in four critical projects in Pinal/Gila counties that will start this year and build upon efforts to upgrade the US 60 corridor, which is a major transportation route connecting the Phoenix metropolitan area and the communities of Florence Junction, Superior, Globe, Miami, San Carlos and Show Low.

Here’s a look at the planned improvements:
  • The first project along US 60 will start in June, when ADOT will build a new westbound climbing lane and widen shoulders along a 13-mile stretch of US 60 from the Oak Flat area to the town of Miami (mileposts 229-242). This $13 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 (mileposts 230-232). When this project starts, blasting operations will require intermittent full closures of the highway.

  • Later in the summer, ADOT will convert the last remaining two-lane roadway segment on US 60 between Phoenix and Superior into a modern, four-lane divided highway. The $45 million US 60 Silver King/Superior Streets project just west of Superior (mileposts 222-227) is expected to take two years to complete and will include improving the urban section of highway in Superior. The five-mile-long widening improvements will improve traffic flow and enhance safety on US 60.

  • East of Superior at milepost 228, ADOT will replace the antiquated lighting in the US 60 Queen Creek Tunnel with a new light-emitting diode (LED) lighting system. This will be the first tunnel in Arizona to have this LED technology. The new lighting system will improve visibility within the tunnel, which was originally built in 1952, by using an adaptive control system that will adjust the lighting level based upon ambient light and weather conditions outside the tunnel. ADOT expects to replace the lighting system beginning this summer, which will require new conduit and wiring in the quarter-mile-long tunnel. The total project cost is estimated to be $3.8 million.

  • The final project on US 60 is a $3 million rock mitigation project along mileposts 228-229, where crews will remove loose boulders along this very rocky and steep section of highway adjacent to the Queen Creek Tunnel.
Motorists are urged to slow down in the work zone and plan ahead to allow for extra travel time once construction starts. ADOT will work to minimize the traffic impacts by scheduling work hours on overlapping projects at different times of the day as much as possible. A detailed schedule of traffic restrictions will be released to the public prior to the start of construction.

And remember, while ADOT works to inform the public about planned highway restrictions, there’s always 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.
