Two small metal tins filled with thick, textured substances: one with yellow paste and one with white paste. Both have a portion scooped out, showing the metal bottom of the tins.

Thermoplastic paint is a very important part of Arizona’s highways. The shiny material marks lane lines, speed limits and even turn lanes. However, it has to meet a certain standard of reflectiveness before it can be used.

That is where ADOT’s Chemical Lab comes in. 

Part of the Materials Group, the Chemical Lab tests every batch of manufacturer thermoplastic or “hot melt” paint to ensure it is reflective enough and has a certain percentage of other ingredients such as binder and pigment. For example, white paint must have at least 40% glass beads, 20% binder content and a yellowness index of less than 0.12. Yellow paint must have at least 20% binder content and 40% glass beads. 

Transportation engineer specialist Matthew Nickday says each batch test takes eight hours. The paint powder is melted in a kettle at 424 degrees. Then, a small portion is placed in a small metal dish and dried. Pieces of the dried paint are baked in an oven in small crucibles, which are then rinsed out with acid in large beakers. (Are you reliving high school chemistry class?) Water is then added to the acid and the resulting liquid is poured into a small tub, which reveals glass beads at the bottom of the beaker.

Those beads are dried in an oven and weighed, and the sample’s percentage of glass beads is calculated.

When the paint batch meets standards, a certificate is issued for the lot and the material used throughout the state.

The most read blogs of 2023

By John LaBarbera / ADOT Communications
December 23, 2023
A graphic that says "Best blogs of 2023" over an image of a typewriter.

It’s been a great year for the ADOT Blog. We published more than 140 articles, covering a wide range of topics from project progress and historical anecdotes to animal rescues and Adopt a Highway updates.

Since it’s the end of the year, now’s the perfect time to count down the ten most-read blogs of 2023.

Number 10: State Route 79’s Gila River Bridge slide. For two weekends in January, crews used an innovative way to replace the Gila River Bridge on SR 79 in Florence. Each weekend, five separate segments of bridge were slid together to create the new structure. Work began on the new $22.1 million bridge in February 2022 by constructing new piers under the existing structure. Then, new bridge segments were constructed on either side of the existing bridge. Once the new segments were ready, they were slid into place. You can also check out the time lapse video of the slide! 

Number 9: Fall foliage in Arizona. The four seasons don’t always work the same way here as they do in other parts of the country. But that doesn’t mean we can’t experience them all without a little road trip! October might be the best time to see fall colors in the high country, but thanks to Arizona’s many mini-climates, you could see leaves changing all around the state well into December. Take a ride down some of our scenic roads and see for yourself! 

Number 8: Winter driving in Arizona’s high country. This blog we published in January becomes relevant again as winter weather heads our way once more. Traveling in the winter is serious business and it’s important to pack a kit in your vehicle for all the “just in cases'' you might encounter. A fully-charged cell phone, extra food and water, necessary medications, prescriptions and a first-aid kit are just a few of the items you should be taking as you venture out into the winter wonderland of Arizona’s high country. And don’t forget to check your windshield wipers, fluids and lights before hitting the road! 

Number 7: ADOT on Jeopardy! If we had a nickel for everytime ADOT infrastructure was mentioned on Jeopardy!, well, we’d have two nickels. That isn’t a lot, but it is odd that it happened twice! In July, the category was “Road” and the clue was: “In Phoenix, The Stack is the name for the interchange where I-17, going north-south, meets this east-west interstate.” The correct response, of course, is Interstate 10. Then in September, the category was “Same first and last letter geography” and the clue: “Driving I-40 from Winslow to Kingman, you might want to stop in this city and maybe take in the Museum of Northern Arizona.” The answer is Flagstaff. 

Number 6: Revisiting the Devil’s Highway. For Halloween this year, we dug into our archives and found some compelling, but definitely spooky, pictures of the former US 666. The route traveled through several states in the southwest as an offshoot of Route 66. Here in Arizona, it went from Douglas to Sanders. If that sounds familiar to you, that’s because today that road is known as US 191. Creepy supernatural tales prevailed throughout the highway’s existence, like UFO sightings, mysterious ghostly hitchhikers and packs of demon dogs. After years of negative connotations and a high rate of sign theft, US 666 was officially decommissioned nationwide in 2003.

Number 5: The Ultimate Bridge Takedown. In April, we made a great leap forward in the progress of the Broadway Curve Improvement project. In one weekend, three bridges were taken down to make room for already completed new ones. This blog served as a preview for the “Ready to Rubble” event, detailing the work happening and warning motorists that I-10 would be closed all weekend in order to prepare for these bridge takedowns. Learn more about the I-10 Broadway Curve Improvement Project at i10broadwaycurve.com.

Number 4: 48 songs about the 48th State. Sometimes we like to have a little fun with our Spotify account. This year, we crafted an ode to Arizona that ran the gamut of decades and genres to bring you a playlist of 48 desert-dwelling tunes. Sure, there’s plenty more AZ songs than 48, but what a fitting tribute to the 48th state. You’ll hear hits from mega-stars like Lady Gaga, Fleetwood Mac and Bruce Springsteen. Plus ditties from hometown heroes The Format, Jimmy Eat World and Gin Blossoms. So take this playlist with you on your next Arizona road trip!

Number 3: Ten most popular plates for 2022. More than 770,000 specialty license plates were ordered in Calendar Year 2022 and we tallied up the top ten in February. The veterans, first responder and Arizona Highways plates were the most-ordered plates. Specialty plates cost $25 for an initial fee and annual renewal, with $17 of the fee going directly to the charitable organization. Order your own specialty plate and support a great cause at azmvdnow.gov.

Number 2: Flex lanes coming to I-17. In 2025, Arizona will have its very first flex lanes along I-17 between Black Canyon City and Sunset Point. These new lanes will run adjacent to the existing southbound lanes, separated by a concrete barrier. Once completed, the flex lanes will typically be open northbound Monday through Saturday and southbound on Sunday, but will open as needed due to traffic and events and crashes that affect traffic flow. In addition to the flex lanes, the I-17 Improvement Project will see 15 miles of roadway widening between Anthem Way and Black Canyon City plus bridge improvements along the entire 23-mile project corridor between Anthem Way and Sunset Point. Stay up to date on the project by visiting ImprovingI17.com.

And a drumroll please!

The number one most read article this year was: Driver license makeover! After about a decade with the same design, Arizona’s driver licenses and IDs got a refresh this spring. They not only come with a fresh, new look, but they also have added security features to help reduce the ability of counterfeit copies and fraudulent uses. The new cards are made from a 100% polycarbonate material and features a laser-engraved black and white photograph, which is much harder to alter. The new look also highlights several state-famous items, like the Grand Canyon, a saguaro cactus, a Ponderosa pine tree and a ringtail, Arizona’s state mammal. Update your license to the new design by requesting a duplicate license, or upgrade to the new design by getting your Travel ID.

ADOT shines in the Electric Light Parade

ADOT shines in the Electric Light Parade

December 7, 2023
Two ADOT volunteers walking down the street in front of a semi truck decked out in Holiday lights for the Electric Light Parade.

Since the late 1980s, the APS Electric Light Parade has lit up Central Phoenix every December with festive celebrations of holiday spirit.

This year, though, marks the return of ADOT’s presence in the annual tradition.

“I’ve been here since 1996, and to my knowledge that’s the last time ADOT was in the parade,” said Mesa Maintenance Supervisor Jerry Turner. “We’re gonna make this look good.”

Jerry and his crew of five worked overnight for five days during the week leading up to the parade, preparing two floats.

The first was a snowplow decked out in white lights and red trim, symbolizing ADOT clearing the way for Santa’s sleigh.

The snowplow was the first of ADOT’s floats in the parade, followed by the grand statement: ADOT’s own interpretation of Rudolph the Red-Nosed Reindeer. A 45-foot-long flatbed trailer provided the support for a manufactured ramp that doubled as the nine reindeer guiding Santa’s sleigh into the night sky. 

Thousands of lights and yards upon yards of garland adorned the extravagant float, which traveled at a leisurely 5 miles per hour along the parade route to the tune of Gene Autry classics.

But before that could happen, a day before the parade, Jerry and his crew hit the road at midnight and made the 23-mile drive from the Mesa Maintenance Yard to the start of the parade route at Central Avenue and Bethany Home Road in Phoenix.

“A snail’s pace,” Jerry remarked. “We don’t want to lose any deer!”

When the crew arrived at the vast parking lot of the North Phoenix Baptist Church, some last-minute adjustments were made. This included styling the inside of the flatbed’s wheels with lights and placing some Christmas gifts on top of the sleigh.

During the parade, Jerry’s crew was joined by three elves who rode in the sleigh, while more than 20 ADOT volunteers walked the 2.5-mile parade route and handed out treats and goodies to the folks lined up to watch the festivities.

ADOT was just one of dozens of organizations with bright, colorful floats lighting up Central Phoenix for this annual tradition.

Will ADOT have a place in the parade again next year?

“I hope so,” said Jerry with a smile.

October 5, 2021

Please allow us to toot our own horn for a moment.

ADOT is proud to announce that we have won two TransComm awards from the American Association of State Highway and Transportation Officials!

Our Twitter account, @ArizonaDOT (give us a follow, won’t you?), scored the top prize in the Best Use of Single Social Media Platform. With nearly 260,000 followers, ADOT’s Twitter account not only provides up-to-the minute tweets on roadway conditions around the clock, but also delivers important information about upcoming highway projects and safe driving campaigns.

Twitter is staffed by a team embedded in ADOT’s Traffic Operations Center. By coordinating with dispatchers and law enforcement, the team brings the motoring public accurate details about lane blockages and unplanned road closures in real-time, so drivers and their passengers can make the best decisions for their travel plans.

Throw in a quiz or two, some humor (when appropriate of course), and answering all the burning highway questions that come our way, and you’ve got a winning combination!

The second award bestowed unto us this year is for something you’re reading right now. Yes, the ADOT Blog won Best Blog at the 2021 TransComm awards. And we couldn’t be more delighted!

Since 2011, the ADOT Blog has delivered digestible bites of insight on a wide variety of topics. We started out as a place for stories about how highways were built and the people who were building them. In the last decade, the ADOT Blog has blossomed into so much more.

Over the past year alone, we’ve brought you pertinent updates on long-term highway projects, road trip recipes, tales about transportation history and personal stories about individual ADOT workers. Not to mention, of course, several important messages from our director, John Halikowski.

You can sift through the archive of the ADOT Blog’s first ten years whenever you’d like right here.

Of course, none of this would have been possible without you, our Twitter followers and blog readers. Thanks for riding on this journey with us. We promise to continue being an informative and entertaining travel companion for years to come.

'Big Foot' former director left big transportation legacy

'Big Foot' former director left big transportation legacy

He was a hearty man with a winning style and warm smile.

He was beloved by his employees, who called him “Big Foot” for his height and size: 6 foot, 4 inches tall and some 240 pounds.

But history will most likely recall the late Justin Herman, Arizona Highway Department director from 1956 to 1973, as the energetic leader who shepherded in the modern state freeway system, including the Black Canyon (Interstate 17), Superstition (US 60) and Maricopa (Interstate 10) freeways.

“During his tenure of office, some of the most important and mammoth advances and improvements in the history of Arizona road building, dating back to the date of Statehood in 1912, have been initiated and completed,” the Arizona Public Employee publication said of Herman in March 1970.

Here are some of those mammoth advances, according to our 2012 Arizona Transportation History report

"Work began on the Maricopa Freeway in 1958, and soon contracts for both new freeways were being issued on a regular basis. By 1961, more than six miles of the Black Canyon were open to traffic, from McDowell Road to Northern Avenue, and work was proceeding at a rapid pace. In late 1964, the combined Black Canyon–Maricopa freeway was dedicated from 16th Street to just north of the Carefree Highway. At a cost of $33.5 million for 30 miles of roadway – more than a $1 million per mile – it was by far the most expensive highway built in Arizona up to that time.”

You can see Herman, second from the left in the photo above, at that 1964 dedication of the combined Maricopa and Black Canyon highways.

Herman was the first and only director of the Highway Department, as before him the chief transportation official had been the state engineer. He served 17 years under five governors, being appointed three times to five-year terms before his retirement in 1973. By then, he had notched 42 years of public service, including 32 with the department.

The next year, 1974, the department he formerly headed became the Arizona Department of Transportation.

Larger than life character

Herman’s 93-year-old son – also named Justin Herman – described his dad in a recent interview as a larger-than-life character with contagious enthusiasm and a drive to get things done.

“He was an all-around great person, one of those people whom others liked immensely, a good-natured and highly intelligent man,” he recalled. “His big mission in life was to help people in any way he could.”

ADOT’s Spotlight bulletin echoed this sentiment in an article about Herman receiving a plaque for his service.

“Herman’s style of ‘personal diplomacy,’ marked by a friendly smile, a ready, powerful handshake, and a kind word to all, made him one of the most widely known state officials in Arizona,” it said.

To get a sense of how widely known Herman was, his son shared about the time he was renewing his license at the Arizona Department of Motor Vehicles, when the woman behind the counter recognized Herman’s name.

“I want to tell you a story,” she told him.

She was only a temporary employee at ADOT, she said, when her husband died of cancer. Around the same time, she was notified that her position would end and she would be let go after that Christmas. She told her supervisor how desperately she needed a job, and he urged her to see the director.

When she went to meet with Herman, he didn’t even know her name. He would meet with anyone regardless of position. She told him her situation, and the next day she was offered a job as a full-time employee.

“He was beloved,” his son said.

Just another cowboy

There was also the time when Herman met with the producer of a movie being shot in Sedona, who was requesting another road for equipment and vehicles.

That producer was John Wayne. And the road, which ADOT built, led to a cottage industry of westerns getting filmed in Sedona, his son said.

Justin Herman, center back, watches then-Gov. Jack Williams declare "Highway Week"

What did Herman think of John Wayne?

“He’s just another cowboy,” he told his son.

Another time in 1950, Herman, his wife and son were on a trip up north when the car broke down.  Herman had to wait hours for another car to come by and give him a lift to a telephone.

He telephoned his employees for help, since at the time he was Superintendent of the Shops. His colleagues were so amused by the irony that they put up a sign at the breakdown location called “Herman’s Crossing.” The site was even on the map for a while, the younger Herman said.

Years later, the younger Herman’s own son, Dan Herman, retrieved the sign – which had become riddled with bullet holes – and put it on his college dorm-room door.

Dan Herman has heard plenty of tales like these about his grandfather, but he was also was privy to his domestic side.

“He puttered in the yard, read Zane Grey novels and cooked sausage and eggs for us on Sundays,” he said.  

If this seems like a long time ago, it was. But the past came to the surface recently when Herman’s granddaughter, Luciana Herman, spotted a photo of him on ADOT’s Twitter feed. The photo at the top of this post, in fact. 

“Such a proud day for my grandfather back in 1964,” Luciana tweeted. “I-10 took up a lot of space in his head in those years as director.”

The second photo on the right shows Gov. Jack Williams signing a proclamation about "Highway Week" in Arizona. while looking on behind him, from left, are William Price, state highway engineer; Herman, and Lew Davis, chairman of the Arizona State Highway Commission. 

Perhaps Herman’s most lasting legacy will be his passion for his job and the people of the state.

His son said: “He just loved his job and the people so much!”

"Transportation is personal. It affects every aspect of our daily lives, giving us the freedom to move where, when and how we want to go. It’s how we get to work in the morning and back home at night. It’s how the products we buy get to stores and how the products we sell get to our customers. It’s how we reach destinations in our state."

We couldn't agree more with those words. Mainly because we wrote them – 10 years ago this month when we published our first blog post.

That's right. A decade ago we were trying to find the right way (in the words of that post) "to help inform people about what we do and why and how we do it." One of the methods we settled on, aside from our fantastic and informative social media accounts, was to start up this very blog. 

Kicking off with that first post on April 11, 2011 we've done our best to meet that goal, whether it be telling you about passive acoustic devices, not-so-visible landscape maintenance tasks, how overhead freeway signage is installed, or all the best highway photos you can find on our Instagram account.

Along the way we've also kept you updated on the behind-the-scenes work of projects important to the driving public, such as when the Loop 303 interchange with I-10 neared completion, when US 89 was close to reopening after a devastating landslide, or when the Loop 202 South Mountain Freeway was ready for traffic

We've also had our fun. Remember the parachuting cows? Or Sasquatches off State Route 260? Or how ... uh ... thematic we've gotten with our overhead message boards?

But at the end of the day the goal has always been to tell you the who, what, when, where, why and how of designing, building and maintaining the state highway system. And we plan to continue doing just that for 10 more years and beyond.

With that in mind, it's only fitting that we close this post the same way we finished the very first one.

"So, I hope you’ll bookmark this page, subscribe to our RSS feed, share our posts, and, of course, leave behind lots of comments.

"Thanks for reading and stay tuned for more to come!"

In Arizona, nothing from Nothing equals a ghost town

In Arizona, nothing from Nothing equals a ghost town

In Arizona, nothing from Nothing equals a ghost town

In Arizona, nothing from Nothing equals a ghost town

By Laurie Merrill / ADOT Communications
September 2, 2020

Does Nothing from nothing leave nothing?

It does, except in Arizona, where Nothing is a ghost town, and that’s not nothing!

Its wind-weathered sign on US 93 between Wickenburg and Kingman is a faded reminder that Nothing’s population – once a thriving 9 – is now, well, nothing.

Nothing might be more accurately described as a ghost settlement, since it never gained incorporated status. It was more of a wide place along the road about 100 miles northwest of Phoenix at milepost 148.5.

But during its heyday, Nothing boasted the “Taint Much Ado” bar, a store, taco stand and gas station. Richard “Buddy” Kenworthy built the businesses after settling the outpost in 1977. The place managed to snag some gamblers and other ramblers traveling between Phoenix and Las Vegas.

After a 1988 fire destroyed Kenworthy’s businesses, he rebuilt the store and garage, but it wasn’t enough to return Nothing to something.  Kenworthy moved on in 2005.

Nothing had a near revival in 2008. A businessman, Mike Jensen, took a liking to Nothing and set up a pizza stand with a portable oven. He even spiffed up the place up with the goal of creating accommodations for RVs.

But by 2011, he too had moved on. It’s tempting to say nothing remained in Nothing, but the worn-out signs and collapsing structures are still there, providing a break in the scenery on the 128 miles between Wickenburg and Kingman. 

You could say it was all for Nothing, like the sign in Nothing:  

Town of Nothing Arizona. Founded 1977. Elevation 3269 ft.
The staunch citizens of Nothing are full of Hope, Faith, and Believe in the work ethic. Thru-the-years-these dedicated people had faith in Nothing, hoped for Nothing, worked at Nothing, for Nothing.

House Rock Flood Repair_US89A

US 89A, an 87-mile stretch between Bitter Springs to Fredonia in far northern Arizona, provides jaw-dropping views of spectacular vistas amid iconic rugged landscape.

It is known for Jacob Lake, gateway to the North Rim of the Grand Canyon, Navajo Bridge over Marble Canyon and a spectacular run beneath the Vermilion Cliffs.

But five years ago, a monster monsoon storm severely damaged 24 miles of the highway. What happened next was a chapter in Arizona Department of Transportation history that shows how quick action, preparedness and cooperation with the private and public sectors rebuilt what is probably the most photographed road in the state.  

It was on Aug. 9, 2015, that a powerful storm dropped nearly 1.5 inches of rain in just 15 minutes on an area that included US 89A. The resulting House Rock Flood carried monster rocks to the highway from the Vermilion Cliffs two miles away and dumped mud everywhere.

“When Arizona Department of Transportation crews arrived on that day in August 2015, what they saw stopped their bulldozers in their tracks: boulders the size of elephants  – 15 feet in diameter – and mud in seven different slides that covered portions of 24 miles of the only road across a wide area north of the Grand Canyon,” ADOT said in a press release. You can see some of that damage for yourself in this slideshow.

The enormity of the disaster prompted Governor Doug Ducey to issue a Declaration of Emergency to allow ADOT to seek approximately $2 million in federal emergency funding to cover the initial costs to reopen the highway as well as long-term repairs, according to another release from the time.

Both the biggest challenge and reward involved getting rid of those mammoth boulders fast enough to reopen US 89A within 24 hours.

“To break up the boulders, ADOT used Boulder Busters,” we wrote in a blog at the time. “These are explosive cartridges that look like 12-gauge shotgun shells but have a thicker rim that would prevent them from being used in a shotgun. Crews drill a hole in a boulder, fill it with fluid, insert one to three shells and trigger an explosion."

That blog even included a little spoof to go with the clearing work. Do you remember the “Ghostbusters” film theme song?

If there’s something strange sitting in your road
Who you gonna call? (Boulder Busters)
15 feet tall
In the northbound lane
Who you gonna call? (Boulder Busters)

US 89A received a makeover to beat all makeovers. The work was so exemplary that ADOT and contractor S.J. Anderson Co. of Mesa received the 2015 Harry H. Mellon Award of Excellence Winner in Job Order Contracting for the US 89A House Rock Flash Flood Project.

“Even with the challenges of a huge task in a remote location, the US 89A repairs were completed in just 53 days, with ADOT providing on-site inspection. The contractor mobilized within days of proposal acceptance, bringing crews and equipment from around the Southwest,” according to the release about the award. 

Tons of stone blocking your path
Who you gonna call? (Boulder Busters)
Can’t make your way
To Jacob Lake
Who you gonna call? (Boulder Busters)

I ain’t afraid of no rocks.

After almost 800 posts, it’s time to change the way we do things here on the ADOT Blog…

Now, we’re not talking about anything too drastic.

We’re still going to share stories that help foster meaningful conversations about transportation – not just about a construction project that will affect your daily commute – but conversations that put people in touch with services we provide and involve people in transportation issues and solutions.

If that line sounds familiar you must be a long-time reader because it is one that we used in our very first post and it still holds true!

What’s changing is that we’re going to have more people telling those stories. In fact, you may have already noticed a few new bylines in recent days. Our hope is that these new voices give you a fresh look at what ADOT does and how we do it.

By the way, we are not going far … or, maybe we should switch things over to first-person and say, I am not going far.

I’m still here at ADOT and may even pop in to write a post every now and then!

So, thanks for reading the ADOT Blog these past five years.

I know I’ve discovered a lot about Arizona’s transportation system by writing this blog. I hope you’ve been able to learn more about the state’s transportation story by reading along. Stay tuned for new and exciting things to come!


A few of our favorite posts...

From asphalt to zipper merges and everything in between, the ADOT Blog has covered plenty of transportation topics over the years. While it’d be impossible to choose the top post, we’ve gone back and selected a few favorites.

We have to start this list off with the ADOT Blog’s very first post – this is where we spelled out all our goals for the blog.

Anything having to do with the Deck Park Tunnel is interesting to us. Through the ADOT Blog, we’ve learned how the tunnel gets clean, what its construction looked like and even why other tunnels are down there too. We celebrated the tunnel’s birthday just last year and have shared a few videos, including this one from the afternoon a produce truck spilled its contents in the westbound lanes.

We really do enjoy the science of transportation, including this post that taught us how ADOT utilizes an Accelerated Weathering Tester to foretell how well paint will hold up against the elements (trust us, it’s more interesting than it sounds).

We love the history of transportation, too. That’s why the From the Archives series is one of our favorites!

Remember Rocky the Ringtail? How about all those posts that show what it takes to move oversize loads through the state? We can’t leave out this dog rescue, or this one. OK, this list really could go on and on, but we’ll wrap it up here.

ADOT Blog marks 600th post

December 5, 2014

Thanks for reading!

We’ve reached a milestone, here on the ADOT Blog.

Today, we mark our 600th blog post! We thought we’d take this as an opportunity to say thank you to all of our readers. We really appreciate everyone who takes the time to visit this blog

Before we get started on the next 600, we want to look back and point out a few of our all-time favorite blogs post...

  • Speaking of milestones, back in 2012, Arizona celebrated its Centennial. To mark the occasion, the ADOT Blog featured a really cool video that documented everything ADOT does in a single day. From construction projects and maintenance work to planning meetings and the MVD, the video gives a comprehensive look at ADOT’s many jobs across the state.
  • Some of our favorite posts are the ones that highlight a transportation-related object or concept that most people don’t know too much about. This post on ADOT’s use of an accelerated weathering tester certainly falls into that category. The accelerated weathering tester is used by ADOT’s Materials Testing team to analyze how well paint will perform on ADOT projects, come rain or shine. We promise, the topic is an interesting one!
  • We’re also really fond of blog posts that can answer the questions that motorists might think of as they’re driving through our state. For instance, have you ever wondered how ADOT cleans and maintains the I-10 Deck Park Tunnel? We’ve got the answer for you in this post from 2011!
  • Featuring the good things that happen out on the road is always fun. This post tells the story of how two ADOT workers were able to rescue a dog off the highway and reunite her with her owners.
  • Showing how ADOT plans for the future has been a big theme here on the blog. We especially liked this post from 2012 that explains how ADOT tests sign sheeting material to see how well it will hold up against the heat for years to come.
  • We’ve developed a few series over the last 600 posts in order to better explain transportation and the state’s highway system. Transportation Defined, From the Archives, Vehicles of ADOT, Science of Transportation, Building a Freeway and From the Rearview Mirror (our newest) are all worth checking out!
  • We can’t forget the videos! We’ve featured so many awesome ADOT videos on this blog. If you haven’t watched them all, you’re missing out!

Finally, we want say our thanks again and remind you that we’re open for feedback. Feel free to tell us about the types of stories and videos you want to see more of. Let us know the transportation questions you have that we haven’t answered yet.
