A news account reported how a severely injured teen ultimately got to a Phoenix hospital for treatment, due in part to help from an ADOT employee who wasn’t identified. Today, we’re sharing more about that employee and his role in the rescue amid flooding in Globe.
Where do speed limits come from? How are highways engineered, signed, striped, etc., to maximize safety? To explain these and other aspects of state highways, we're pleased to have State Traffic Engineer Kerry Wilcoxon as this week's On the Road With ADOT guest.

Most people don’t find the sound of traffic especially soothing … ADOT certainly recognizes this and is constantly working to minimize the impacts to surrounding neighborhoods from the noise of new freeways.
Most of the signs ADOT produces have to be pretty big so drivers can read them, but one of the newest is simply massive… At 16x16 feet, a new sign welcoming motorists to Arizona is among the tallest in the state. It recently was installed on Interstate 8 near Yuma; however, it was made in Phoenix, and as you can imagine, moving a sign that size isn’t a simple task (see video above and photo slideshow below).
Crews are busy adding more than 80 lane miles of high occupancy vehicle (HOV) lanes to two Valley freeways – 30 miles in both directions on Loop 101 in the west Valley and 12 miles on east- and westbound Loop 202 in Chandler that will link directly to HOV lanes on the Loop 101 (Price Freeway) and Interstate 10.
Memorial Day weekend is here and if you’re headed out of town you probably have your travel plans all wrapped up by now. Hopefully those plans already include some safety preparations … if not, here are a few things to think about before hitting the road!
The bridges over Pinewood Boulevard in Munds Park have been carrying Interstate-17 traffic for the past 53 years and now it’s time for some well-deserved reconstruction! ADOT has already begun the project that will rebuild the bridges and ramps on I-17 at Munds Park , an area just south of Flagstaff . Work started last month and is scheduled to wrap up by fall 2012.
It’s a sad truth, but trash thrown onto our state’s roadways really adds up. That’s because it’s not just a few random soda cans, cigarettes or empty bags littering the roads and surrounding areas. In reality, more than 800 tons of trash gets picked up in Arizona each year.
Drivers along eastbound Loop 202 might notice something’s different on their Monday morning commute – but it’s going to take a very perceptive eye to catch the change. This weekend ADOT is installing signs with a brand new typeface on the Red Mountain Freeway between Loop 101 and Country Club Drive. Although the change is slight, the new signs should be a little easier to read!
ADOT can’t just construct a freeway wherever and however it wants… Building a road actually requires a lot of careful planning, thought and exploration long before the first construction crews ever arrive on site.
Instead of holding their annual meeting in a conference room, key stakeholders in one of ADOT’s oldest partnerships took a bus tour through the Tonto National Forest to get a close look at the projects made possible by their collaboration. And, I was lucky enough to tag along!
When a new section of highway opens, we here at ADOT celebrate right alongside the local communities, citizens, contractors and stakeholders who all played a part in getting the road built.
