Our weekly challenge features a unique Arizona image and this week is no different.

This century-old other bridge over the Salt River deserves some recognition.

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

Ever wonder how a bridge, whether it be a stately metal connector over a canyon or a concrete slab over a wash, comes into being? And why they take the form they do? Well, let us tell you!

Angeline Hoagland would be amazed. After all, she was but a toddler when she died near the Old Black Canyon Highway in 1889, but stories of her death – and reports of her “ghost” – are alive and kicking today.

You are never too young to care about your community, something demonstrated recently by a group of middle school students who helped clean up a section of US 191 near Morenci.

If you're looking for a scenic Arizona drive, today's "Where in AZ??" location might be a good one!

Whether you are on two wheels or four, now is the time to make motorcycle safety a priority.

Things are looking pretty bright for our project to install LED lighting in the Deck Park Tunnel - pun intended.

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. 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.

Nothing ruins a great shot of Arizona's beautiful scenery like someone's trash. But, picture being the one who helps ensure the state looks camera ready by adopting a mile of highway.

Arizona is full of scenic roads, but it's hard to beat State Route 260 as it winds its way between Cottonwood and the White Mountains.

This body of water is a popular recreational area for many. Join our weekly challenge if you can identify this spot.

For the #ADOTKids out there, bicycles are how you get around. Since we are interested in all forms of transportation at ADOT, here are some tips to remain safe while riding through your neighborhood!

Let us just take a moment to say how much we love I-40. How much, you might ask? Oh, we love it to the tune of $275 million.

Once the project at Pinto Creek bridge on US 60 is done, ADOT will have accomplished more than just replacing a bridge. It will have helped experts preserve an endangered species of cactus that grows in the area.

Daunting engineering challenge or monster B-movie material? We are looking at a tangled web for Throwback Thursday.

The holiday weekend is a week away, but now is the time to prepare if you'll be traveling.

This week's "Where in AZ??" location is a bit out of the way.

For this 11-year-old interested in engineering and architecture, there was nothing better than going to the office with Dad.
