When it comes to describing some hauls, the term “oversize load” is a major understatement. We’re talking about the enormous “super-loads” driven through the state each day. Maybe you’ve seen them on the freeways … they’re the trucks lugging gigantic transformers, generators, turbines, and even houseboats.

Much has changed since ADOT got its start in 1927. Back then, the agency was known as the Arizona State Highway Department and roads certainly were built a little differently. Methods, materials and technology have changed so much since then.

In Arizona steps are being taken toward that future with the operation of METRO Light Rail and the anticipated launch of Tucson’s modern streetcar project. While ADOT is not responsible for rail transit in the state, the agency does play an important role …

The wait is over! After more than three years since work first started, West Valley motorists now have a new and improved drive on I-10 as it stretches through Buckeye, Goodyear, Avondale and Tolleson.

Some terrain is so rough and rocky that even heavy-duty machinery can’t break through. That was the case last Thursday when ADOT crews used more than 7,000 lbs. of explosives to remove roughly 8,000 cubic yards of material along SR 260, about 20 miles east of Payson.

With the number of road construction projects happening around the Valley right now, chances are you’ve driven through an active construction zone or two recently. Maybe you’ve noticed the lane lines in some of these construction zones look a little different. A little … temporary?

Ever been stuck on the side of the road? Perhaps a flat tire was to blame, or maybe an overheated engine forced you to pull over. Whatever the reason, most will agree the side of a busy freeway is not the ideal parking spot.

Few situations are as stressful as hitting traffic on your way to the airport … especially if you’re holding on to that non-refundable ticket for a trip out of town. That’s why ADOT is working on reconstructing the State Route 143/Sky Harbor Boulevard Traffic Interchange to improve access to and from the airport.

Airports may not be the first thing most people think of when it comes to ADOT … but the Arizona Department of Transportation actually plays an important role in aeronautics and the development of airports across the state. Just like automobiles, all aircraft based in Arizona must be registered with MVD. Those registration fees, along with flight property, aircraft dealer licensing and aviation fuel taxes – paid by pilots and aircraft owners – go toward the state aviation fund.

In less than a year, spectacular ramps and bridges have risen from bare ground in the southeast Valley. By this fall, they’ll link 12 miles of new high occupancy vehicle lanes on the Loop 202 (Santan Freeway) with Interstate 10 and the Loop 101 (Price Freeway) in Chandler -- see the project's progress in the slide show above.
