The ADOT MVD Community Connections team was recently recognized with the AAMVA Region 4 2025 Community Service Award for their continued efforts to support community organizations across the state.
Two bridges under construction on US 93 north of Wikieup didn’t look much like bridges until recently, as they were little more than concrete piers jutting up from a dry wash. That all changed rapidly in the past few weeks, as crews lifted...

Over the past several years, ADOT has worked to transform the highly traveled US 93 between Wickenburg to the Hoover Dam from a two-lane highway to an environmentally friendly four-lane, divided highway. A project of this scale will always present its share of issues, but widening the final section – from Kingman to the Mike O’Callaghan - Pat Tillman Memorial Bridge – provided ADOT with an especially unique challenge …
Last week when we told you about National Preparedness Month, we briefly detailed the role ADOT plays when it comes to public safety. But, there’s a whole lot more to say on the subject, and who better to write about it than ADOT’s very own Emergency Manager…
A couple months ago we told you how ADOT works to minimize the noise impact a new freeway has on surrounding neighborhoods. Well, similar efforts also are made when it comes to air quality …
It’s not often that a tree gets wrapped up in a mystery, but a lot of unanswered questions surround one Juniper growing next to I-17. Some Arizonans might already know about the tree – it’s actually sort of famous around the state and even has its own Wikipedia page.
If you’ve been following along in the blog, you know that we’ve been chronicling ADOT’s reconstruction of the Mescal/J-Six bridge in southern Arizona since it was severely damaged when two semi trucks collided underneath it back in March. Completion of the fast-tracked bridge reconstruction is slated for later this month.
If you live and drive the Loop 101 in the West and North Valley you probably noticed the first stretch of HOV lanes on the eastbound Loop 101 recently opened. These new lanes already have helped to ease congestion in the North Valley, especially during the morning commute. You may have also noticed that the westbound HOV lanes appear to be done as well, but are not opened. ADOT has not decided to taunt you – these lanes aren’t open yet for a reason.
An ADOT Highway Operations Supervisor came across a sight Monday morning that he’s never seen before … As he was driving by Jeddito Wash on SR 87, Elliott Koinva noticed that thousands of tumbleweeds had clustered together to form a kind of solid wall.
Now that you know a little about the ADOT permitting process involved with moving oversize loads, take a look at the latest heavy haul to cross Arizona’s highways. The video above shows just a portion of the journey this 285-ton load took beginning the first week of August.
Last week we gave you an update on how the new Mescal/J-Six bridge is coming along... You might also remember that the night the damaged bridge was taken down, the old Marsh Station bridge was also demolished just a few miles away. It was a huge project that required completely shutting down I-10 for the night.
With roughly 240,000 vehicles driving through it each day, the I-10 Deck Park Tunnel needs the night off every once in a while for a good, thorough scrub! Just about every four months, the tunnel is closed to traffic in order to allow crews the chance to wash the walls, maintain the ventilation systems and check on the tunnel’s 3,700 light fixtures (about 150-200 light bulbs are changed out each quarter!).
