Sound walls are built to block sound waves and … actually, that’s about all they’re designed to do. Despite serving pretty much just one single purpose, sound walls are important features in freeway design – especially to those living near a freeway.

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?
