GLOBE – A new US 60 bridge over Pinto Creek opened to traffic Friday, Sept. 17, replacing a 72-year-old structure on the only route between Superior and the Globe-Miami area.

The Arizona Department of Transportation began the $22.7 million bridge replacement project 23 months ago, constructing the new bridge just feet away from traffic that continued using the existing structure. Then on the night of Sunday, Sept. 12, work crews closed US 60 between Superior and Miami for a round-the-clock operation to realign the roadway to the new bridge.

The 695.5-foot-long bridge opened to the public about noon Friday. While both bridges were designed for two lanes of traffic, the new structure also features 8-foot-wide shoulders and can handle heavier loads.

“US 60 is a critical route for passenger vehicles and commercial traffic, including heavy loads from mines in the area,” said ADOT Southeast District Engineer Bill Harmon. “By completing this new bridge at Pinto Creek, we’re making sure the highway will remain reliable and safe for decades to come.”

The bridge is expected to handle roughly 7,200 vehicles a day.

While the largest milestone of the project is complete, drivers should expect periodic lane restrictions and delays in the area through the rest of 2021. Crews will work to restore the project site to its natural state over the next several months, with work beginning shortly to remove the existing bridge.

The old bridge, opened in 1949 with an estimated lifespan of 50 years, remained safe for traffic but had reached the end of its useful life. As noted on plaques at each end of the structure, the American Institute of Steel Construction bestowed an annual award of merit for 1949’s Most Beautiful Steel Bridge, Class II. Days after closing the old bridge, crews removed the plaques so they can be donated to local historical societies.

GLOBE – Motorists who travel on US 60 between Superior and Miami need to begin planning for a full closure of the highway from Sept. 12-17 while crews with the Arizona Department of Transportation realign the roadway to meet with the new Pinto Creek bridge.

During the 5-day closure, motorists should expect an extra hour of travel and a 10 percent grade as traffic is detoured onto state routes 77 and 177 through Winkleman. Eastbound traffic in Superior will be directed onto SR 177, and westbound traffic will be redirected at the west end of Miami.

Motorists with a destination in the closed segment of US 60 will be allowed to pass the closure points, but no vehicles will be allowed between Top-of-the-World and Pinto Valley Mine Road. 

The closure is scheduled to begin at 10 p.m. Sunday, Sept. 12, and end at noon Friday, Sept. 17. The closure is subject to change based on weather.

While ADOT has worked to minimize the impact of the bridge replacement project, the extended closure is required because of the work involved with shifting the highway roughly 30 feet while also raising it 8 feet to align with the new structure. Crews will work 24 hours a day during the closure.

The work that will take place during the closure represents a major milestone in the two-year, $22.7 million project to replace the 72-year-old bridge. Once traffic is shifted onto the nearly 700-foot long bridge, construction crews will begin the process of removing the old structure and restoring the project site.

Also, drivers should expect a 4-hour closure in October when crews take down the old bridge. Through the rest of the year, occasional lane restrictions will be required as crews haul away remnants of the old bridge and complete other roadway improvements.

American engineer and educator James Kip Finch said “The engineer has been, and is, a maker of history.”

That can definitely be said of the engineers and team members working on the Pinto Creek Bridge project as they are creating a replacement for a 72-year-old bridge, located on US 60 about six miles west of Miami, to keep a southern Arizona community moving.

When the project began in 2012, many factors came into play, including addressing historic preservation with the Federal Highway Administration and bridge aesthetics with the U.S. Forest Service. Another consideration was environmental impact, which led to the mitigation and conservation of the Arizona Hedgehog Cactus in the canyon.

An interesting development was the discovery of a mine adit, which is basically a prospector’s tunnel, a consideration during the original construction in the 1940s. The team did 3D modeling of the foundation excavation limits to determine the type of foundation that would reduce any risk due to the mine adit.

ADOT used value engineering to develop improvements to the construction feasibility review and efficiency of the bridge, saving about $1.5 million.

“Adjustments were made to the foundations and column reinforcing for efficiency and constructibility,” Bridge Designer Rafe Davis explained. “A bid alternate was developed in the plans and specifications which provided the contractor flexibility.”

The bridge is now about 73% complete. The girder lift took place in April, but it was an involved process

“The girders took more than three months to fabricate, not including the time for required submittals and to prepare the structural steel shop drawings,” Project Supervisor Kim Vanvolkinburg said. “Once girder delivery to the project began, it took them about six weeks to set and splice all the girders and cross frames. The contractor brought in multiple cranes, and had to move them several times due to the logistics of working adjacent to the existing highway and within the canyon below.”

The projected completion date is January 2022.

“This will likely adjust some as there is a lot of work yet to be completed,” Vanvolkinburg said. “Hopefully, the weather will cooperate.”

GLOBE – US 60 will close between Miami and Superior the night of Wednesday, July 28, as crews pour a portion of the concrete deck on the new Pinto Creek Bridge.

The highway will close to all traffic between 8 p.m. and 4 a.m. as crews work in close proximity to the existing bridge. While US 60 is scheduled to reopen at 4 a.m. Thursday, July 29, drivers should be prepared for lane restrictions and flaggers directing traffic if work is necessary past that time.

With the new bridge nearly complete, the next major step of the $22.7 million bridge replacement project will be shifting the roadway alignment to the new bridge. The work will occur in September and require a full five-day closure of US 60. ADOT will provide notice of the closure dates when the schedule is confirmed.

When US 60 is closed, traffic will be detoured to SR 177 in Superior and SR 77 in Globe. The detour includes a 10% grade and will significantly increase travel time.

Motorists with a destination between SR 177 and Top-of-the-World to the west of Pinto Creek, or between Miami and Pinto Valley Mine Road east of Pinto Creek, will be allowed to pass during the closure. No vehicles will be allowed between Top-of-the-World and Pinto Valley Mine Road.

GLOBE – Full overnight closures are scheduled on US 60 between Miami and Superior Wednesday, July 21, and Wednesday, July 28, as part of the Pinto Creek Bridge replacement project.

The Arizona Department of Transportation will close the highway between 8 p.m. and 4 a.m. on July 21-22 and July 28-29 while crews pour the concrete deck on the new bridge. While the highway is scheduled to reopen at 4 a.m. the following Thursday mornings, drivers may encounter alternating lane restrictions and flaggers directing traffic if work extends past that hour.

During the closure, US 60 traffic will be detoured to SR 177 in Superior and SR 77 in Globe. The detour includes a 10% grade and will significantly increase travel time. Traffic will not be allowed to queue at the closure locations.

Motorists on US 60 with a destination between SR 177 and Top-of-the-World west of Pinto Creek or between Miami and Pinto Valley Mine Road east of Pinto Creek will be allowed to pass. However, no vehicles will be allowed between Top-of-the-World and Pinto Valley Mine Road.

There are some of us at the ol' ADOT Ranch who were born and raised here in Arizona. Some would say Arizona natives are as rare as hen’s teeth, but the truth is we have no idea what that “hen’s teeth” saying actually means. 

So let’s skip it. 

The issue here is the desert. Those of us who grew up here tend to think it’s quite beautiful. You may or may not agree, but, ahem, we’re right. We will concede that beauty is in the eye of the beholder. 

But what is NOT in the eye of the beholder is the idea that whether you think the desert is a plain brown landscape or you’re among the truly enlightened who see it as an ever-changing canopy of color and light, the environment is worth preserving. 

Where does ADOT fit into all of this? Like a glove. 

To wit: 

Since 2018, there has been a joint effort by the Arizona Department of Transportation and the Desert Botanical Garden in Phoenix to protect an endangered species of cactus that grow only in one tiny area of Arizona. That area also happens to be where ADOT is building a replacement bridge over Pinto Creek on U.S. 60 near Globe-Miami. 

A few years ago,  ADOT began the project to replace the current bridge that went up during the Truman administration. Before that work began, ADOT partnered with botanists from the Desert Botanical Garden to make sure endangered hedgehog cactuses that grow in the construction zone were rescued. 

Project work will be completed in 2022 and the cactuses replanted. 

The rescue effort required several of the members of the Desert Botanical Garden team to rappel into the canyon, carefully dig up, cover and transport the plants to the Garden complex in Phoenix where the cactuses are being cared for and propagated.

One cool thing is that not only will the cactuses come home, there will be more of them because of the great work the Desert Botanical Garden is doing to make sure these plants don’t just survive, but thrive. 

Oh, and there will be a great new bridge, too. But that’s a story for another day. 

No matter your opinion of the desert, or, for that matter any part of our diverse and beautiful state, preserving the land and the wildlife is not only the law but it’s  worth doing, and doing well. That’s an ADOT priority.

There's something beautiful about building a bridge. Whether it's the satisfying geometry of a bridge's lines and shapes or the sheer immensity of its size, the various construction stages are a sight to see. 

And when it comes to the new Pinto Creek Bridge on US 60, you have the added appeal of stunning desert scenery and staggering slopes set against an Arizona blue sky. You can see for yourself in this spectacular slideshow captured by a talented ADOT photographer. 

Motorists traveling along US 60 between Superior and Globe recently might have been lucky enough to catch a glimpse of a sky-high crane hoisting 35 massive girders into place.  

This was not a trifling matter. These girders weigh between 450,000 and 70,000 pounds. That's between 25 and 35 tons. And they range in length from 91 to 127 feet. 

The new bridge will be 695.5 feet length and supported by three piers rising from a canyon floor. It is being built adjacent to the old one, which was erected in 1949 and will be removed. Despite multiple life-extending projects, the 72-year-old span is still safe for motorists but nearing the end of its usefulness. 

The next US 60 closures are expected to take place overnight when crews pour bridge-deck concrete in mid-summer. A five-day closure will be scheduled when the bridge is nearing completion toward the end of the summer. 

You can sign up to receive traffic alerts relating to the bridge's construction at the project's page on our website or using this electronic signup sheet here. And you can always check az511.gov to find up-to-date information on construction or other restrictions.

During scheduled closures of US 60, motorists will be detoured to State Route 77 and State Route 177. This detour could add as many as 45 minutes to a trip, however, travel time may be significantly longer depending on the driver's starting point and destination.

A highrise of sorts is now standing within a few feet of US 60 where the Pinto Creek Bridge replacement project is underway east of Superior, but drivers passing through can be forgiven for overlooking it.

That’s because the towering structure is a 158-foot tall bridge pier rising from the bottom of a deep canyon, topping out roughly at the same level drivers pass through the area on the existing bridge.

The bridge pier is significant not just for its height, but also because its construction comes at what is roughly the halfway point of the $22.7 million bridge replacement project. This video gives a different perspective of how much progress ADOT is making, and you can really appreciate the height of the new piers as well as the existing bridge. If you still want more, we recently shared a fantastic slideshow showing what crews have been up to.

Once the three sets of bridge piers are complete in the coming months, crews will work into early 2021 to construct the bridge deck. That work will be a little more visible to drivers, as crews will work within about 30 feet of the existing bridge and at the same level as passing traffic.

Fortunately for drivers, ADOT will continue to minimize traffic impacts by keeping both lanes of travel open on US 60 in the project area during nearly all other stages of the project. 

Drivers can expect some restrictions when the concrete bridge deck is poured in early 2021. When the project nears completion next summer, US 60 will close for up to 5 days while crews realign the highway to the new structure. The existing bridge will be dismantled after traffic is shifted to the new structure.
