Joe Heller, our resident engineer on a big project getting underway in the North Valley, joins On the Road With ADOT this week to explain what's coming over the next two and a half years, including a flyover ramp connecting northbound I-17 with Loop 303.
A major component of the work will be building the direct ramps to create the freeway-to-freeway interchange. When completed over the next two-and-a-half years, drivers will skip the traffic signals at the current Loop 303/I-17 diamond interchange.
Engineers at ADOT play a vital role in building and maintaining Arizona’s roads. During National Engineers Week, Feb. 22-28, we’re celebrating engineers and the work they do to keep Arizona moving.

The new interchange and realignment will feature wider entrance and exit ramps with traffic signals, overpass bridges that will provide for future growth, and a design that will accommodate a future project to add a westbound I-10 climbing lane starting at the Ocotillo Road exit east of SR 90.
Judging from the video above, crews have been busy since we last checked in on the SR 260 widening project east of Payson… Go watch the video from a year ago to compare with today’s and see if you agree (we’ll wait right here!).
This might sound cliché, but ADOT really is getting rid of the old to make room for the new… It’s happening right now on the San Carlos Apache reservation as ADOT crews construct a new bridge to replace the US 70 Gila River Bridge at Bylas.
Ever survey an Arizona freeway during a monsoon? If you have, you’re likely to have seen debris in the roadway, landscapes in disarray, damage and even flooding…
The bridge crossing the Gila River outside Florence has quite a few distinctions in its history.
As ADOT prepares to open a new eastbound on-ramp and westbound off-ramp at Sarival Avenue and I-10, crews have been busy adding the finishing touches…
Interstate 10 moves approximately 260,000 vehicles through the Phoenix metro area every day. It’s a vital link for commercial traffic traveling to and from California and New Mexico; for intrastate travelers going between Phoenix and Tucson; and for a respectable number of travelers going to and from many of Arizona’s southern towns and cities.
The “mystery tree” on I-17 still has us baffled, so imagine our bewilderment upon seeing these photos of a shoe tree off of State Route 87, south of Payson.
Hard to believe, but after more than 200 blog posts we’re still surprised by some of the things we find out here at ADOT. For example, did you know there’s a small yard adjacent to an ADOT field office parking lot filled with dozens of sign samples?
QR codes are big nowadays … you see them everywhere. They’re the two-dimensional bar codes that provide a quick link to web pages for your smart phone. They are not only fun (there’s something kind of awesome about scanning a code and instantly being taken to a web destination), but they’re also convenient and that’s why ADOT’s Motor Vehicle Division is utilizing QR codes along with a new mobile site to provide customers the ability to renew vehicle and aircraft registration on the go!
